Wifi Plug Output support with Tasmota (new Tasmota Output module)

[smguth]

Is your feature request related to a problem? Please describe. Wired relays and cable management hastles could be alleviated. Describe the solution you'd like I would like integration with Mycodo outputs.
This is a wifi plug that can recieve commands via SSH. I was considering using gpio wired relays but this seems like a perfect solution to avoid all the wires. I just purchased a unit on amazon, waiting for it to arrive. https://www.amazon.com/gp/product/B00MWR6ZY4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 My thought is I can use output commands with Mycodo and it will work just fine but also want the Mycodo community to know about this smart plug because I think they would like it and come up with ideas for it that I possibly would not .
Future enhancement suggestion. Integration with Mycodo

Additional context Add any other context or screenshots about the feature request here. Please see this link it tells about the wifi plug further http://www.anites.com/2015/01/hacking-kankun-smart-wifi-plug.html

I love the wireless outlets. The Command Output that's currently available in Mycodo would be the most appropriate for this. Essentially, a script needs to be developed that turns it on and off, then that script can be executed by the Mycodo Output Controller to control the plug. When you get the plug, we can start developing a working script to test.

[smguth]

Yeah I was wondering if it was worth bothing to add a check to ensure that the relay state changed after the control was sent. If i did bother with it then do i send the control again and check the state again. After so many failed attempts trigger an alert or email. Probably just start with having it send the command and work from there though. I have a feeling it will always work as long as it is in range

That AC plug looks awesome as it has ssh options.

[SAM26K]

@smguth do you have a sales link to the US version? Unable to locate so far. Thanks.

[smguth]

@SAM26K I only found it on amazon with the link from above https://www.amazon.com/gp/product/B00MWR6ZY4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1. With the holidays I am still waiting for it to arrive too. There was mention of finding it on AliExpress for about $20 in the other link but I didn't go down that route. I am planning on verifying that everything works smoothly when the one I ordered from Amazon comes in then probably try to source them cheaper as $30 per plug is a bit more than I ideally want to spend. If anyone does find a better source for these please let us know!

[kizniche]

Wifi plugs seem to be in abundance in the market. I'm sure there are many that have already been hacked or have an open API of sorts out-of-the-box.

https://www.amazon.com/s?k=wifi+plug

Where were these things a few years ago!? Some interesting finds:

I found my holy grail of power strips, with the rare use of solid state relays, however it looks like this product has been discontinued: https://github.com/arendst/Tasmota/wiki/LeFun-SK2-Smart-Power-Strip-(Model-ZLD-44USA-W)

[SAM26K]

@smguth How long ago did you order it? Says 10 days for delivery on Amazon.

[SAM26K]

A lot of the wireless plugs can be hacked by burning Tasmota firmware but often it's very difficult to connect to the data ports. The Kankun is the first one I've heard of that has an open interface and reflashing isn't necessary.

[kizniche]

I bought the LeFun power strip with hope I'll be able to put Tasmota on it. The SSRs are really appealing for my applications.

[SAM26K]

That one looks good and on the Tasmota list of deviices.

[smguth]

Wow I hadn't heard of Tasmota before but now I need to learn about it. Do some of these smart plugs monitor power usage too?

[smguth]

https://blakadder.github.io/templates/kmc-4.html found this guy says its a energy monitoring smart plug might order this next after my kankun comes in

[SAM26K]

If you pick a device for Tasmota flashing google it first. I look for detailed instructions with pictures.

[SAM26K]

Most of the wireless AC adapters use the ESP8266 chip which is the target for Tasmota. Some devices are easy to connect to and others are very difficult to connect for reflashing.

[SAM26K]

BTW the energy monitoring software is stock with many of the device's original firmware but not sure if it's included with Tasmota. You can use Mycodo to set expected current draw for a device and have a calculated value for power (and/or energy) logged to the database.

[smguth]

Thanks SAM26K I think i'm starting to get a feel for some of this stuff now :D . I'm still very new to Mycodo so might be off base with my understanding of it. Trying to get my project off the ground yet but having fun learning as I go. So if my device is Tasmota compatible does that mean it is compatible with Mycodo or might there still be configuration/integration yet?

[kizniche]

If you can get Tasmota on it, which will allow for switching on/off via HTTP or SSH, then Mycodo can be configured to use it as an output.

[SAM26K]

@smguth please flollow up when you finally get your Kankun device. May work with Mycodo out of the box without Tasmota.

[smguth]

Okay I'll keep you updated Amazon says it will arrive the 16-19 so possibly today.

[smguth]

Got this guy in over the weekend had a few hurdles to overcome with the set up. For what ever reason the android app wouldn't work for me so I had to configure it with ssh and get it on my wifi network. The instructions worked but I had to set my password key to psk2 instead of what their guide said. Also, to control the relay I had to use root@koven:~# echo 0 > /sys/devices/platform/leds-gpio/leds/i-konke\:red\:relay/ brightness root@koven:~# echo 1 > /sys/devices/platform/leds-gpio/leds/i-konke\:red\:relay/ brightness

My model must have been slightly different than the one in the guide

[smguth]

my /etc/config/network file looks as follow:

config interface 'loopback' option ifname 'lo' option proto 'static' option ipaddr '127.0.0.1' option netmask '255.0.0.0'

config globals 'globals' option ula_prefix 'fd54:f988:6027::/48'

config interface 'lan' option ifname 'eth0' option force_link '1' option type 'bridge' option proto 'static' option ipaddr '192.168.145.253' option netmask '255.255.255.0' option ip6assign '60'

config interface 'wan' option proto 'dhcp' option ifname 'eth1'

config interface 'wwan' option proto 'dhcp'

and my /etc/config/wireless:

config wifi-device 'radio0' option type 'mac80211' option channel '11' option hwmode '11ng' option path 'platform/ar933x_wmac' list ht_capab 'SHORT-GI-20' list ht_capab 'SHORT-GI-40' list ht_capab 'RX-STBC1' list ht_capab 'DSSS_CCK-40' option htmode 'HT20' option disabled '0' option country 'CN'

Hi guys, after playing around with ssh keys I was able to get this far. I created a script on the Pi that ssh's into the kankun and runs a script that turns on the relay. If I run the script from my pi it turns it on and off with both sets of scripts. When I try to run the script from mycodo it does not work. I'm wondering if its a user or permissions thing.

the script on the pi hosting Mycodo: ssh root@kankun /root/script_on.sh

the script on the kankun smart plug: echo 1 > /sys/devices/platform/leds-gpio/leds/i-konke\:red\:relay/brightness

[SAM26K]

Looks promising. Can you disable the password requirement? You are probably right about permissions. Also try using Python code instead of ssh.

[SAM26K]

Also is there errors in the daemon log?

[smguth]

I did see errors in the log but not sure if they are related. See screenshot It looks like mycodo thinks its executing the commands succesfully from my understanding of it. I'll look into writing this in python gonna have to do the holiday thing here shortly though.

[SAM26K]

Having problems with my Linux controls since installing the new Raspbian o/s and Mycodo 8.2.x. In the process of converting them to Python.

[SAM26K]

Do you know what's causing the GPIO error?

[smguth]

I have a Dht11 connected to pin 17 and it's giving me data so I was a little surprised to see the error. I never put a resistor in series with the the data line now that I think about it so maybe I'll do that and see if it fixes it

[kizniche]

I can add the option to execute the commands as user pi or root. Currently commands are executed by default as user pi.

[SAM26K]

That would be nice.

[SAM26K]

@smguth any progress? Advise not to update with the vendors firmware. You may be able to install Tasmota OTA (over the air)) without the need to wire directly into the device.

[smguth]

Hey @SAM26K I havnt gotten much further. I was hoping to try replace my scripts with python code but I've never coded in python before so that's been a hurdle. I can try getting tasmota on it. That will protect the manufacturer from locking me out?

[kizniche]

I can add the option to execute the commands as user pi or root.

I had forgotten about this since it's not really related to this issue, but I was going through issues today and found it. Better late than never. I just committed an update that adds the ability to select which user (pi, mycodo, or root) executes Linux Command Outputs.

I also forgot to give an update on the power strip I ordered. The seller cancelled the order and that was the only supplier I could find for that particular version.

[smguth]

Well I got this working. I reinstalled my operating system and started over with a clean mycodo install. There were alot of steps but I followed the notes I had in this issue. I also had to run ssh root@wifiplug "tee -a /etc/dropbear/authorized_keys" < ~/.ssh/id_rsa.pub From my raspberrypi in order for the pi to send the commands to the kankun smart plug without a password. Also, I added wifiplug to hosts file so I didn't have to keep using the ip address. Now when I click On and off buttons the relay in the kankun plug turns on and off

[kizniche]

I'm reviving this thread since I just ordered 4 individual wifi outlets that include power monitoring.

https://templates.blakadder.com/efun_SH331W.html https://www.amazon.com/gp/product/B07DCJ7TDR

Hopefully I won't have a reoccurrence of what happened last time and the seller cancels my order. I'll let you know how flashing of Tasmota and building the output module go after I receive the product.

[kizniche]

All 4 plugs were quick to flash Tasmota and I can now control them via MQTT publish commands from an MQTT server (mosquito) hosted on the same Raspberry Pi Mycodo is installed on. Each plug had the MQTT server set to localhost, as well as the host for the MQTT outputs. The Mycodo output topic was set to "cmnd/tasmota1/Power" with tasmota1 being your device name, and the ON Payload to "on" and OFF payload to "off".

It's a very nice system and I haven't had any issues in the past week or so they've been running. I'm closing this issue since we've figured out connectivity with Tasmota.

[aTanguay]

Hi-

Is there any way you can elaborate on setting this up? Very new to MQTT and I am puzzled. I have Tasmoto installed on my plugs, and mosquito server installed running on the same Pi as Mycodo, but I can't seem to get these to talk to each other.

Here's my MQTT setup in the plug,

and here's my server output config..

From here, I'm just trying to use the On/Off buttons on the output manually. But I get nothing.

Sorry for the newbie question, but this is definitely some new ground for me.

[aTanguay]

I was close. Apparently, I had not installed my MQTT broker properly, so it wasn't able to accept outside connections. Reinstalled it and now it's good. For others trying this, I followed this to get MQTT going...

https://randomnerdtutorials.com/how-to-install-mosquitto-broker-on-raspberry-pi/

From there I got the info from my info screen on the switch...

Its configured this way...

Then, this is what the output looks like in Mycodo....

Really simple actually at the end of the day. Very exciting, works great, over the air.
