Adding a new template/module for a new Wallpad 4CH Touch Switch (Tuya TYWE3S based device) #5545

Closed Rambylon closed 5 years ago

Rambylon commented 5 years ago

Have you look for this feature in other issues and in the wiki? Yes, i did look in the other issues and in wiki but i didn't find solution as this device was not using GPIO pins for control. It uses Serial Data for controling through RX and TX ports. The "Tuya Dimmer" module works for only one channel control from Tasmota(the first one) but it receives state change from the device for all channels, though it shows only one channel in Tasmota ( CH1 on/off in device-> turns on/off in tasmota, CH4-> on/off in device-> turns on/off in Tasmota, and respectively for all the 4 channels).

Is your feature request related to a problem? Please describe. A clear and concise description of what the problem is. The problem is that this device (Wallpad 4CH Touch Wifi Switch) is Tuya based and it uses Serial data for communicating with a secondary MCU for switching the relays, rather than using on-board GPIO pins for relay control. So the Module configuration in Tasmota was useless as they can only configure the GPIO pins for I/O. It can be controlled via the console and MQTT using the serial codes but it can not transmit the state changes in MQTT.And can not be controlled from the Tasmota GUI.

Describe the solution you'd like A clear and concise description of what you want to happen. I have identified the Serial codes used to communicate with the secondary MCU for relay control (both command codes and response codes). I can successfully use the serial codes for testing the relay controls in the Tasmota Console. The solution that i wish is the implementation of these codes to create a new template (or module) in Tasmota for this device. So that the device can get controlled from the Tasmota GUI and MQTT.

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered. If the above mentioned idea is not possible, then i wish a method for transmitting the state data of the device through MQTT. As the switches are not configured, getting the state data from the device through MQTT is not possible.

Additional context Add any other context or screenshots about the feature request here.

Jason2866 commented 5 years ago

You can use rules to get the device usable with Tasmota. Solution is similar to this https://github.com/arendst/Sonoff-Tasmota/wiki/LC-Technology-WiFi-Relay

Rambylon commented 5 years ago

@Jason2866 when in generic template the serial communication doesn't work. when configuring GPIO 0 and GPIO 2 for relays while in tuya dimmer template it doesn't even show the relay control in the main menu.

Jason2866 commented 5 years ago

You have to use module generic. I dont understand why serial communication doesnt work for you. I use serial bridge function in module generic....

Rambylon commented 5 years ago

dont know. it only send and recieve serial data in "Tuya Dimmer" template.

thirug010 commented 5 years ago

I bought the US version of the Tuya 4 Ch touch switch, it does not use the Tuya serial, it directly use the gpio's as below.

{"GPIO0":"25 (Relay5)","GPIO1":"0 (None)","GPIO2":"0 (None)","GPIO3":"19 (Button3)","GPIO4":"23 (Relay3)","GPIO5":"17 (Button1)","GPIO12":"20 (Button4)","GPIO13":"24 (Relay4)","GPIO14":"22 (Relay2)","GPIO15":"21 (Relay1)","GPIO16":"18 (Button2)"}.

the same is available in the Aliexpress but i dont have the link, you can get it from Alibaba chat

Rambylon commented 5 years ago

thank you. how is the touch response in the switch? does it respond immediately or it takes a slight delay to react?

thirug010 commented 5 years ago

when I use generic with GPIO it has 1 sec delay but after defining the template in tasmota it works fast.

{"NAME":"Tuya 4 Channel","GPIO":[255,255,255,19,23,17,0,0,20,24,22,21,18],"FLAG":0,"BASE":18}

GPIO0 is the Wifi Icon LED if you want to control.

Rambylon commented 5 years ago

good work

blakadder commented 5 years ago

I think this thread has reached a conclusion and therefore its being closed

thirug010 commented 5 years ago

Hi

I have done some analysis and found the following, have special Tuya Devices not fully supported by Tasmota Tuya code, as Tuya get more popular we may expect some new devices.

My findings,

  1. It assume only one power for Tyua Serial devices. update devices_present = 4 in sonoff.ino, will allow you to add button or extra power for current Tuya dimmer with GPIO's devices_present = 1 fro dimmer. In my case it 3 (dimmer 2 , dimmer power 1 , other power 3) else if (TUYA_DIMMER == my_module_type) // if TUYA_XXXXXX if you defined new template { devices_present = 3; // devices_present = Setoption; to better support for new devices }
  2. It assume the Power is always Device 1, but in reality it can change based on the device. standard Tyua dimmer power is 1but various for device, as per the Protocol tuya_buffer[6] dimmer id

Example: I have the Tyua device has Fan Dimmer and Light switch (link : https://www.amazon.com/gp/product/B07M77KCYJ/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1 )

Hi @Rambylon,

I have updated the 6.5.0 code to support 4 gang Switch. I tested with Wemo + serial Terminal for the communication,

  1. Tasmota Web UI ON /OFF send the Serial to the Terminal ( tested for all switches ) 2.. MQTT power command trigger the Serial to the Terminal
  2. Serial Data from your Excel switch ON /OFF the Tasmota / MQTT.

update the sonoff.ino and xdrv_16_tuyadimmer.ino from the .zip folder and compile and update the firmware.

Thanks Thiru

sonoff.zip

Rambylon commented 5 years ago

thank you @thirug010 i flashed the update through ota. and the firmware now recognizes 4 switches. switching them works perfectly when done one by one. but when more than two switches are on and when we try to turn off one it doesnt work. the relay doesnt click and the display shows off for a second and goes back to its previous state (in openhab). In tasmota web UI it shows like this tuya problem 6

the console shows

04:33:51 SRC: MQTT

for POWER4 OFF it sends TX data of 4th relay ON. but it should send off data. the same happens for the POWER3. the weird thing is it sends correct data when all other switches are off. this only happens when another switch is on.

why do you think this happens? and share me a way to contact you personally other than this issue. im also from your state.

@Rambylon

Did you get any further with a working Tuya touch switch in Tasmota? I have a different 4 gang touch switch (non-dimmer) but the serial codes you provided are identical.

blakadder commented 5 years ago

@MikeSaint Take a look at https://blakadder.github.io/templates/oil_diffuser_550ml.html for an example on how to get some control of the switches

Rambylon commented 5 years ago

@MikeSaint no. There is no further development in the matter. Still hoping for further development in the tuya driver.

thirug010 commented 5 years ago

Hi All,

Me and @Rambylon is working in the separate thread to resolve the issue with Custom Tuya based devices (1 dimmer + 1 relay aka Fan Light switch , 4 Relay Tuya serial switch .. ). We will keep you posted once all the issues are resolved

Thanks Thiru

MikeSaint commented 5 years ago

That's great news @thirug010 If you want me to do any testing on the Tuya touch switches (3 & 4 gang) I have, please let me know.

blakadder commented 5 years ago

reopening since the code is being worked on

thirug010 commented 5 years ago

We are able to test code in the Tuya 4Ch serial based device it is working but has some slowness working to fix it

I will adjust it the code for 3 gang and fan light (1Dimmer 1 relay) devices.

Will keep you posted.

@MikeSaint could you send the serial data for 3 gang device for the testing.

Thanks Thiru

thirug010 commented 5 years ago

I have updated the tasmota to support the custom tuya devices, It can be flashed with USB or OTA with minimal firmware But not with Tuya-Convert directly ( it is 516kb bin file)

You can the following options to update the code 1 . Use the attached (.zip) files and update your Sonoff-Tasmota-6.5.0 Branch 2 . Use cloned the version of the Sonoff-Tasmota-6.5.0 here Important this code is not tested on all tuya devices, update it on your own risk, make sure compare the serial data, if you need help please reach out to me

Summary of Changes:

./sonoff _settings.h sonoff.ino xdrv_01_webserver.ino xdrv_16tuyadimmer.ino ./tools decode-config.py

This code will support up-to 8 Tuya devices as per the TUYA-MCU Protocols. it can be all 8 Relays or 1 dimmer + 6 relays but only one Dimmer can be used at a time.

Here is sample devices and SetOptions .

Steps use Tuya Dimmer as Switch (4Gang) .. Thanks to @Rambylon for Testing and Support

  1. Make sure the Serial Data is matching with your device tuya_4gang_wallpad_uk.xlsx
  2. Reset Current Configuration --> it will make the device as basic sonoff
  3. Update the new firmware
  4. SetOption63 as 0 --> will disable the dimmer slider control
  5. SetOption38 as 4
  6. Select Module as Tuya dimmer image

Steps use Tuya Dimmer as Fan Dimmer and Light Switch (1 Dimmer, 1 Relay)

  1. Make sure the Serial Data is matching with your device Fan Dimmer Data.zip
  2. Reset Current Configuration --> it will make the device as basic sonoff
  3. Update the new firmware
  4. SetOption63 as 1 --> will enable the dimmer slider control
  5. SetOption38 as 3 --> 1-SSR, 2-Dimmer, 3-Relay
  6. SetOption34 as 2 --> (Optional it will be set based on the feedback from MCU on the 1st dim packet)
  7. Select Module as Tuya dimmer

Notes:

Steps use Tuya Dimmer as Switch (3Gang) Not Tested

  1. Make sure the Serial Data ( first 3 switch) is matching with your device [tuya_4gang_wallpad_uk.xlsx] (https://github.com/arendst/Sonoff-Tasmota/files/3192203/tuya_4gang_wallpad_uk.xlsx)
  2. Reset Current Configuration --> it will make the device as basic sonoff
  3. Update the new firmware
  4. SetOption63 as 0 --> will disable the dimmer slider control
  5. SetOption38 as 3
  6. Select Module as Tuya dimmer

Hi All, I too had to analyze thirug010 the code as I have tuya switches 1,2,3 and 4 gang and for a while now I've been looking at a solution to process the tuya messages.

I must say I am very impressed at the coding techniques. Whoever coded the TuyaSerialInput(); and the TuyaPacketProcess(); my hat is off to you!

I don't have a full understanding of the whole Tasmota environment so I have one question but before that, I have a couple of comments...

@thirug010 - also some great work on the analysis and suggestion for improving and incorporating more than just your standard tuya dimmers. here are some hygienic changes I suggest:

your code:

no need for if statements. Just pass the tuya_buffer[6] to the ExecuteCommandPower.

so it becomes:

case TUYA_CMD_STATE: if (tuya_buffer[5] == 5) { // on/off packet

    AddLog_P2(LOG_LEVEL_DEBUG, PSTR("TYA: RX - %s State"),tuya_buffer[10]?"On":"Off");

    if((power) && (power != tuya_buffer[10])) {
      ExecuteCommandPower(tuya_buffer[6], tuya_buffer[10], SRC_SWITCH);  // send SRC_SWITCH? to use as flag to prevent loop from inbound states from faceplate interaction
    }
  }

Same thing for the TuyaSetPower(); function

instead of: if (source != SRC_SWITCH && TuyaSerial) { // ignore to prevent loop from pushing state from faceplate interaction if(deviceId == 1) // 3 is dimmer { TuyaSendBool(1, rpower); } if(deviceId == 3) // 3 is dimmer { TuyaSendBool(3, rpower); } status = true; } return status; } ...

the function becomes:

bool TuyaSetPower(void) { bool status = false; uint8_t deviceId = XdrvMailbox.notused; uint8_t rpower = XdrvMailbox.index; int16_t source = XdrvMailbox.payload;

if (source != SRC_SWITCH && TuyaSerial) { // ignore to prevent loop from pushing state from faceplate interaction

AddLog_P2(LOG_LEVEL_DEBUG, PSTR("TYA: SetDevicePower.rpower=%d, deviceId= %d"), rpower, deviceId);

TuyaSendBool(deviceId, rpower);

status = true;

} return status; }

just a little bit more elegant, that's all.

and now for my question...

Q1. Everything works but I cannot find which parameter to pass for the the switch number (01, 02, 03 or 04) so the reply needs to be...

55aa 00 06 0005 S# 01 0001 ON 55aa 00 06 0005 01 01 0001 01 (checksum) 55aa 00 06 0005 02 01 0001 01 (checksum) 55aa 00 06 0005 03 01 0001 01 (checksum) 55aa 00 06 0005 04 01 0001 01 (checksum)

55aa 00 06 0005 S# 01 0001 OFF 55aa 00 06 0005 01 01 0001 00 (checksum) 55aa 00 06 0005 02 01 0001 00 (checksum) 55aa 00 06 0005 03 01 0001 00 (checksum) 55aa 00 06 0005 04 01 0001 00 (checksum)

So I need to pass it the switch number 01, 02, 03 and o4. Currently whatever toggle I press on the main page the switch number (S#) is 01.

I have updated the tasmota to support the custom tuya devices, It can be flashed with USB or OTA with minimal firmware But not with Tuya-Convert directly ( it is 516kb bin file)

You can the following options to update the code 1 . Use the attached (.zip) files and update your Sonoff-Tasmota-6.5.0 Branch 2 . Use cloned the version of the Sonoff-Tasmota-6.5.0 here Important this code is not tested on all tuya devices, update it on your own risk, make sure compare the serial data, if you need help please reach out to me

Summary of Changes:

./sonoff _settings.h sonoff.ino xdrv_01_webserver.ino xdrv_16tuyadimmer.ino ./tools decode-config.py

This code will support up-to 8 Tuya devices as per the TUYA-MCU Protocols. it can be all 8 Relays or 1 dimmer + 6 relays but only one Dimmer can be used at a time.

* To Enable or Disable Dimmer control use SetOption63 --> 1-Enable 0-Disable

* To Set No of devices / Relays / Dimmer  use SetOption38 (_**Note:** require re-boot to apply the change_)
  Example 4 Gang SetOption38 - 4

Here is sample devices and SetOptions .

Steps use Tuya Dimmer as Switch (4Gang) .. Thanks to @Rambylon for Testing and Support

1. Make sure the Serial Data is matching with your device [tuya_4gang_wallpad_uk.xlsx](https://github.com/arendst/Sonoff-Tasmota/files/3192203/tuya_4gang_wallpad_uk.xlsx)

2. Reset Current Configuration --> it will make the device as basic sonoff

3. Update the new firmware

4. SetOption63 as 0 --> will disable the dimmer slider control

5. SetOption38 as 4

6. Select Module as Tuya dimmer

Steps use Tuya Dimmer as Fan Dimmer and Light Switch (1 Dimmer, 1 Relay)

1. Make sure the Serial Data is matching with your device
   [Fan Dimmer Data.zip](https://github.com/arendst/Sonoff-Tasmota/files/3192220/Fan.Dimmer.Data.zip)

2. Reset Current Configuration --> it will make the device as basic sonoff

3. Update the new firmware

4. SetOption63 as 1 --> will enable the dimmer slider control

5. SetOption38 as 3 --> 1-SSR, 2-Dimmer, 3-Relay

6. SetOption34 as 2 --> (Optional it will be set based on the feedback from MCU on the 1st dim packet)

7. Select Module as Tuya dimmer

Notes:

* Use Power 1 and Dimmer Control to turn ON/OFF and set the Dimmer Value

* Use Power 3 for the control Light Switch (relay)

* Power 2 is just dimmer control Just sent the dimmer packets. toggle buttn does not work

Looks like you've already done that. That's great! Ok one more thing...

This is the status update from a 4 Gang Tuya switch panel with "Cooperative Processing by the MCU and Wi-Fi Module". i.e. image

the MCU sends this status for a 4 gang (no dimmer)

55AA 01 07 0005 01 01 0001 00 0F 55AA 01 07 0005 02 01 0001 00 10 55AA 01 07 0005 03 01 0001 00 11 55AA 01 07 0005 04 01 0001 00 12 55AA 01 07 0008 07 02 0004 00000000 1C 55AA 01 07 0008 08 02 0004 00000000 1D 55AA 01 07 0008 09 02 0004 00000000 1E 55AA 01 07 0008 0A 02 0004 00000000 1F 55AA 01 07 0008 65 02 0004 00000000 7A 55AA 01 07 0008 66 02 0004 00000000 7B 55AA 01 07 0008 67 02 0004 00000000 7C 55AA 01 07 0008 68 02 0004 00000961 E7

so I'm not user what 07, 08, 09 and 0A are. I think they have something to do with dimmer (not implemented in this switch

but 65, 66, 67 and 68 are nothing to do with the dimmer and the code is misinterpreting it as a dimmer packet because the code length (0x00 0x08) in byte 5.

I then discovered that it looks like one of them is the voltage and the other is the current

55AA 01 07 0008 65020004000000007A 55AA 01 07 0008 66020004000000E560 55AA 01 07 0008 6702000400000241BF 55AA 01 07 0008 680200040000096EF4

and it looks like the two last bytes are a word, i.e.:

word(tuya_buffer[12],tuya_buffer[13]);

So how hard is it to a) stop misinterpreting those as dimmer settings and b) perhaps process them as voltage (V) and current (mA)?

Rambylon commented 5 years ago

@MaliMrav i dont think analogue operation(process them as voltage (V) and current (mA)) works when the tuya processes serial data. i guess its a software and hardware limitation.

MaliMrav commented 5 years ago

46471FD9-9476-41E9-8278-459F8CBCBE96 The tuya switches I have have a sensor that is read by the MCU and passed on to the tuya Smartlife app, via the last two messages 67 and 68.. as per pic Ive managed to get the Tasmota to display it via Addlog to confirm. Hence, my issue is that when the code reads the last 4 lines it interprets them as dimmer values and plays havoc with the switches, randomly switching them off as they read a 0 or a duty less than 25%, I assume.

Anyhow, if disable the dimmer functions, the device behaves as it should.

thirug010 commented 5 years ago

@MaliMrav, Thanks for your finding, I will use the serial data to update the code, Please share the details about the switch, I would try get and try it myself

thanks thiru

thirug010 commented 5 years ago

@MaliMrav , Random switching due to the unknown packets on the non-dimmer device was fixed already in the dev branch, Please take the latest dev branch code.

MikeSaint commented 5 years ago

@MaliMrav Great information on the power usage and the diagram on "Cooperative Processing by the MCU and Wi-Fi Module".

I have flashed 3 devices to the dev branch Tasmota and it's working fine as a serial switch (apart from SetOption38 to 4 makes them reboot but not retain the setting). But that's not the end of the world.

Recovering from a failed install / bad setting / user error is my problem of the week.

Mine are all TYWE3S based Tuya 3 and 4 gang serial switches.

Has anyone worked out how to USB flash one of these serial 4 gang switches if the OTA flash fails and it goes into a mode where it doesn't connect to WiFi or create it's own SSID for management (aka sort of bricked)?

3 devices worked fine and are fully functional. I've got one that was running Tasmota basic and flashed to the new Dev branch of full Tasmota but failed once it was set to be a Tuya Dimmer and rebooted. The other failed because I stupidly put some version of ESPEasy firmware on it that didn't have OTA upgrade capability or my WiFi settings (my bad).

Being serial, the buttons don't respond as GPIO-0 would on a Sonoff device. I've tried loads of combinations that would work 100% on a Sonoff device using ESPEasy on a USB to TTL serial stick, but these serial switches don't seem to behave in the same way where we'd simply ground GPIO-0 to put it into flash mode.

Grounding GPIO-0 on these units during startup doesn't seem to do anything at boot. I'm pretty sure that is my issue.

Has anyone worked out how to flash one of these? Could you please share the process and exactly which TYWE3S pins were used?

MaliMrav commented 5 years ago

Yes, I've worked it out

The reason why it fails with usb is because the MCU sends data every 5 seconds on the same line as your USB serial (RXD0). So to successfully update your firrmware via USB you need to cut the RXD0 track, write your firmware and then re-solder the track back on.

As far as connections are concerned, it is pretty simple:

USB MCU +3V ---> +3V GND ---> GND TX ---> RXD0 RX ---> TXD0

Then you need to have a push-button (momentary) switch with one side to GND and the other side to GPIO0.

the sequence:

  1. wire up the USB Serial interface with your MCU. Note don't plug in the USB cable into your PC yet

  2. press and hold the programming switch and while holding the switch, place the USB cable into your PC.

  3. you can let go of the switch now, your MCU is now ready to be programmed.

  4. Once programmed you just power-cycle the MCU.

Every time you need to program it you need to follow the sequence. Note: the reason you need to power-cycle it is because this is the cheapest method without needing to wire a reset switch.

Hi Thiru,

Hi Thiru,

Ok attached is a capture of the serial port (capture.txt) and the same capture just formated for better reading (capture-new.txt capture.txt capture-new.txt

so the format seems to be

55AA 01 07 0005 01 01 0001 01 10 <--- Switch # 01 and is ON 55AA 01 07 0005 02 01 0001 01 11 <--- Switch # 02 and is ON 55AA 01 07 0005 03 01 0001 00 12 <--- Switch # 03 and is OFF 55AA 01 07 0005 04 01 0001 01 13 <--- Switch # 04 and is ON

55AA 01 07 0008 07 02 0004 000000001C <--- No clue 55AA 01 07 0008 08 02 0004 000000001D <--- No clue 55AA 01 07 0008 09 02 0004 000000001E <--- No clue 55AA 01 07 0008 0A 02 0004 000000001F <--- No clue

55AA 01 07 0008 65 02 0004 000000007A <--- No clue 55AA 01 07 0008 66 02 0004 000000F26D <--- I think this is the current 55AA 01 07 0008 67 02 0004 00000244C2 <--- I think this is the power or something (although P = V x I) 55AA 01 07 0008 68 02 0004 0000095BE1 <--- I think this is the voltage

66 and 67 have some value only when some switches are on (so they must be the current. 68 has always got a value so I assume that is the voltage (~240 Volts in Australia)

the 0004 refers to there being the function length as per below diagram

@MaliMrav , Random switching due to the unknown packets on the non-dimmer device was fixed already in the dev branch, Please take the latest dev branch code.

In the dev branch the SetOption63 --> 0 and SetOption38 --> 4 doesn't seem to work. So the options to set the switches and remove the dim is only in the tuya-new, right?

Do I now need to hard-code the switch count?

arendst commented 5 years ago

SetOption38 is wrong and is deleted on latest dev branch. Use SetOption41 instead as documented here #6039

meingraham commented 5 years ago

@arendst is this functionality no longer supported then?

set IRReceive protocol detection sensitivity minimizing UNKNOWN protocols

arendst commented 5 years ago

@Mike, it is still supported as documented. The problem was both IRReceive and Tuya used the same storage location. That has been changed now as IRReceive continues to use SetOption38 and Tuya uses SetOption41.

meingraham commented 5 years ago

OK. So you were referring to the improper use of SetOption38 in the Tuya PR. SetOption38 as documented for IR remains. Check. All's well.

MaliMrav commented 5 years ago

Hi Thiru,

So the switches can be found at http://www.szmakegood.com/

MaliMrav commented 5 years ago

SetOption38 is wrong and is deleted on latest dev branch. Use SetOption41 instead as documented here #6039

ok so the switch count is fixed; Great!

What about removing the dimmer slider, SetOption63 --> 0 ?

Further more, I still have the status lines interpreted as dimmer settings. My workaround is pretty much a hack to disable the reading of what the function incorrectly assumes it to be a dim value

else if (tuya_buffer[5] == 08 { // dim packet <--- this is a wrong assumption because there are other use cases where the 6th byte is 08, not just dimmer values. in my case there are 8 lines that are status values: (Voltage, power, and some I have not worked out yet.) (see my previous post for more details.

so I've just disabled it by looking for a different value, for now: else if (tuya_buffer[5] == 0) { //from 8 to 0

Regards, MaliMrav
