DRU Heater support

[sweebee]

Hi,

I have a DRU Heater at home. It has a 433Mhz remote that homeduino can receive. I tried to make a protocol with rfcontroljs, but i can't get it to work. Is there someone who can help or create a protocol?

I receive codes like this:

RF receive 298 644 26356 0 0 0 0 0 01101110011010101001101010101010011012" debug: received: [ 298, 644, 26356 ] 01101110011010101001101010101010011012

and this is the remote (4 buttons).

[Icesory]

Post pls the output for all buttons

[sweebee]

Well, i receive different things every time, rolling code maybe?

set button does not send rf. The other buttons i have to hold to receive rf.

[koffienl]

Do you have a temperatur on your display? If so, chance is that it is not sending up or down command but actual temperature.

[sweebee]

Yes there is. The up and down buttons steer the gas valve. So maybe a different code for every step? But the temperature shows the actual room temperature. it doesn't change when pushing a button.

I tried to put the valve down to the max, but then the rf code still changes.

[Icesory]

I don't see a rolling code. Homeduino is more sensitive as it needed. Pimatic filters the wrong timings.

[sweebee]

I see, so the code is always the same but the timings are wrong? Is there a way to add this to homeduino? This DRU remote?

[Icesory]

I think I can do this at the weekend. Can you change some addresses on the devices? It would make it easier

[sweebee]

This are all the addresses, i tried to assign new codes, but its always the same. But a friend has the same remote, so reading out that remote wil work too, to make it easier?

Here are my addresses:

[sweebee]

Additional info i followed:

A code is selected automatically for all Mertik Maxitrol electronics from among 65,000 random codes available. The receiver has to learn the code of the handset: • Press and hold the receiver’s resetbutton until you hear two (2) acoustic signals. After the sec- ond, longer acoustic signal, release the reset button.

• Within the subsequent 20 seconds press the (small flame) button on the remote handset until you hear an additional long signal confirming the code is set.

NOTE: This is a one time setting only, and is not required when changing the batteries in the remote or receiver.

[Icesory]

Yes pls post the codes from the other remote. Only with a different I can see the right adress coding

[sweebee]

Unfortunately the remote was different, and not 433Mhz. I will try to find a different one.

[sweebee]

Okay, i got the same remote from a neighbor, this are the codes from that one:

[Icesory]

The informatios are a little bit less. So i can make a switch protocol that should work. But when later some other guy need this protocol too and we got more informations the protocol and the configuration can be changed. In fact to this after a update of the homeduino plugin it is possible, that your config is broken.

[Icesory]

I have start the first version for the DRU protocol. You can download it from my git repository or you wait until @sweetpi has merged it into the official release. https://github.com/Icesory/rfcontroljs/commit/64566ea19253f00a1adbac5f46392952e71641a3#diff-1

As device you should use the HomeduinoRFButton Device. https://github.com/pimatic/pimatic-homeduino#buttons-device-example

[sweebee]

Thank you! I tried it but it didn't work?

The config looks right. How do installed the new protocol? And get you a rf message in pimatic, when you press a button

[sweebee]

I get 'Done' in pimatic when i push a button. And [pimatic-homeduino] debug: data: "ACK" in the log file.

I downloaded al your files from your frcontroljs and uploaded it to:

pimatic-app/node_modules/pimatic-homeduino/node_modules/homeduino/node_modules/rfcontroljs/

[Icesory]

Have you the possibility to check the rf message with a second arduino?

[sweebee]

unfortunately not.

[Icesory]

you can make a fast test. go into the folder pimatic-app/node_modules/pimatic-homeduino/node_modules/homeduino/node_modules/rfcontroljs/lib and open the file switch9.js go to this line pulseLengths: [300, 600, 23000] and replace it with this pulseLengths: [320, 640, 26330]

[sweebee]

Replaced it, but still not working.

[Icesory]

So late online xD. Pimatic-homeduino works so far? Do you use it with other RF stuff? (I try to locate the failure)

[sweebee]

Yea, just back from night work. I use it with 4 Kaku switches, 3 kaku dimmers, 1 kaku pir and one doorbel. all working great.

[Icesory]

Nice. Can you flash the the raw example from RFControl on the arduino. You must set the receiver pin in the code an upload it to the arduino. After this open a terminal program and look on the serial port for communication (pair:8N1 baud:11520). When you press now a button you get a lot of numbers this I need. Best for all buttons. On, off, up, down

[sweebee]

Im not using an arduino, I'm using an Attiny45.

[Icesory]

The Attiny is an active filter? It is highly recommended to use a Arduino. It reduces the cpu load by 40%

[sweebee]

yes as an active filter, my cpu load is about 5%

[Icesory]

Ah I don't own a active filter. But it gives the possibility to get the raw code. @sweetpi how can he do it?

[sweebee]

Looks like i have to make a Raspberry Pi with transmitter/receiver for a friend this week, so when I have finished that, i could read the rf code that pimatic is sending for the heater.

[sweetpi]

You could modify the virtualhomeduino code to print the raw timings: https://github.com/pimatic/virtualhomeduino/blob/master/vhduino.cpp#L82-L89

This is the c program that is used if you don't use a arduino. It's like the serial connection but it just reads from the stdinput. Ofcause it only works on the raspberry pi.

[sweebee]

i got this from plight-raw (raw data), don't know if you can use it.

[Icesory]

Now i lost a little bit the overview, Can you please describe exactly what you received with which system and from which remote?

[sweebee]

I received that codes directly from the remote with Pimatic and an arduino. I used the attiny before. I'm nog using the attiny anymore.

[Icesory]

The new ones are 8 unit longer then the old ones.

01100110011010101001101010101001011012 old
01101001 01100110011010101001101010101001011012 new

With pilight received codes are long as the old ones. Some thing is strange here

[sweebee]

This could be the issue because my attiny didn't work very well?

[Icesory]

Are you able to make a serial connection to the arduino?

When yes. Stop pimatic. Start a SerialMonitor Send this command

RF send 4 PIN 323 641 22468 0 0 0 0 0 0110100101100110011010101001101010101001011012

replace PIN with the pin number from your sender on the arduino.

I opened the monitor. and received READY, but i can't type??

With a linux monitor i cant help you. for this you musst google. On windows you can use the arduino IDE or HTerm

[sweebee]

I tried this: echo -e "RF send 4 PIN 323 641 22468 0 0 0 0 0 0110100101100110011010101001101010101001011012" > /dev/ttyUSB0

and serial sends ACK but heater does nothing

PIN! You must change this.

echo -e "RF send 4 4 323 641 22468 0 0 0 0 0 0110100101100110011010101001101010101001011012" > /dev/ttyUSB0

output: ACK

but no response from heater.

But don't know if baudrate is right etc. Tried with arduino software i get ready but when i send a command nothing happens.

[Icesory]

Try this, it is the on command

RF send 4 4 323 641 22468 0 0 0 0 0 01100110011010101001101010101001011012

Nothing happens. when I try a code from a light (kaku switch) it works with the light. but the code from the heater does nothing to the heater.

Its just strange, every other receiver works when sending RF send but not the heater. Could this be a different problem? with filtering?

[Icesory]

Can you please capture the raw timings with pilight new? and please make the files bigger. I need more data to verify the code.

[sweebee]

Pilight-raw you mean? Is that possible with homeduino?

[Icesory]

the data from pilight-raw is very good. i can use it.

[sweebee]

I have installed pilight but how do i get pilight-raw communicate with homeduino?
