Can you please add all screens?

Hi Mimiix, 👋 vishivishy here. Hope you've been well.
Sorry I couldn't figure out earlier how to get additional cluster info screens. I've added them now, do let me know if there's anything else needed.
Thanks!!

It s perhaps a 1 line edit modification.

Do you have a linux machine with full OS to test a code modification ?

Edit:
I confirm it s a _TZE200_la2c2uo9 clone, so the code is already ready.

Edit2:
Bad news, sorry, it s a 2 gangs, so not sure it will be possible to create a fake endpoint.

[vishivishy]

Hi @Smanar thanks for looking into this. So is it that 2 gang can not be supported by deconz or that I wont be able to test the new modified code?

[Smanar]

Can work, as you are not using common Mac adress, from the issue it seem the only one other device that use this mac adress is a covering.

You have a linux machine with full OS ?

[vishivishy]

I can setup a new linux vm if that works.. (if you can give me details of the setup)

[Smanar]

Yes it work on VM, so you need to set the VM, update the OS, install deconz using package method https://www.phoscon.de/en/conbee2/install

For the rest you have the procedure here https://github.com/dresden-elektronik/deconz-rest-plugin/wiki/Compiling-the-REST-plugin-for-device-specific-testing
So for you, after having installed deconz :

sudo apt install deconz-dev
git clone --branch tuya_dimmer_test_1 https://github.com/Smanar/deconz-rest-plugin.git
cd deconz-rest-plugin
qmake && make -j2
sudo cp ../libde_rest_plugin.so /usr/share/deCONZ/plugins

But from the code, you need to have at least the on/off working for one gang ?

[vishivishy]

I already am able to use on/off for 1 gang on the current homeassistant-deconz (6.10.0) firmware(26660700).
but do not have control over brightness or the second gang.

@Smanar so I ran the updated plugin on the linux vm and I'm able to control brightness of the 1 gang that I was able to turn on and off earlier.
I do however see 2 additional lights in the Phoscon app but turning them on/off does not translate to actions on gang 2.

here are some screenshots from the test

Yes the code create 3 "light", it s because this part is a hack used for 3 gangs devices.
Have modified the code again, to try to enable the second gang.

cd deconz-rest-plugin
git pull
qmake && make -j2
sudo cp ../libde_rest_plugin.so /usr/share/deCONZ/plugins

[vishivishy]

Hi @Smanar! I've tested the new changes and here are the findings:

• I still have 3 lights visible in the phoscon and deconz webapp
• I am able to turn on/off and change brightness of gang 1 in Phoscon app as one would expect.
• I am able to "only turn on" and change the brightness of gang 2 in phoscon app (the light does not show if it is turned on, it always shows light is off. and sometime after setting the brightness, the brightness slider moves back to 0% brightness as it seems to not be able to read the status of the device) and because the phoscon app thinks the light is not turned on it does not let me turn off the light. I have tried showing this in the following screenshots.

The light turned on and brightness was set correctly on the device but that does not reflect in the phoscon app later (problem only with gang 2)

• The deconz webapp is not able to turn on any of the lights. so both gang 1 and gang 2 do not respond in the deconz webapp but other single gang relay based zigbee switches can be turned on/off from the app.

I still have 3 lights visible in the phoscon and deconz webapp

Yeap, this is normal for the moment, will be corrected in the future with ddf file, I need to remove this hack

And you was right for the rest, it s because the return state was bad. Have updated the code again.

But for the code is not working using the second Webapp, it s strange, are you able to find some logs somewhere ? using the dev console, deconz logs, or others ?

[vishivishy]

Hooray! Both the gang lights are working as expected in the Phoscon app!
But as for the deconz webapp its the same outcome as before. I did however follow the step 9 from following guide to generate the attached log file.

https://github.com/dresden-elektronik/deconz-rest-plugin/wiki/Compiling-the-REST-plugin-for-device-specific-testing

I could only see these errors in the logs but have attached the log file in case you need to check something else out.

I kept the test quick and short under 1 minute so there is not too much noise and log file stays small, hope this helps. Do let me know if you need me to get you any other logs. Thanks!

[Smanar]

Hu .., In fact I have some problem ATM, I have no internet connexion, and no deconz running to check ^^ (for at least 2 days)
But I can't understand why it work on phoscon and not the old webapp.

00:07:58:771 API error 6, /lights/4/state, parameter, id, not available

Something is bad on the request

Something you can try is enabling the developper console on your web browser to check http request or easier check for "http" logs on deconz.

Take care care thoses logs are realy talkative, so enable only "http", on thoses logs you will see incoming and outgoing requests from deconz, so you will see the request made by phoscon and the one made by the old webapp.
Perhaps you will see something different in them ?

[vishivishy]

Hi @Smanar, so I had a look at the requests being sent by Phoscon and deconz webapp, and seems like the two apps are sending different payload in the put request.
Phoscon is sending this and getting response code 200

{"on":true,"bri":25,"transitiontime":9}

and deconz webapp is sending this and getting response code 400

{"id":"4","on":true}

it seemed like the api is not expecting the "id" parameter in the payload so I tested on postman and can confirm that when we send id param in payload the server sends a 400 response, but if I remove the id param the server responds with 200 and turns on the light.

An interesting thing I noted is that sending "id" parameter in payload for a device with single gang does not return a bad request 400 response and it turns on the light as shown in the screenshots below. (*But the phoscon app does not send the id param in the payload regardless of what kind of light it is, probably because the "id" is a path parameter)

2 gang device

1 gang device

[Smanar]

Ok have added a code part to make the "id" skipable for the tuya part. (Same command to update your code)
But I have not understand yet why it work for simple gang ....

[vishivishy]

Thanks @Smanar everything seems to be working now!! What's next?

[Smanar]

Have just made the PR.
ATM we are waiting for DDF file, so lot of PR are locked in waiting list.

Next is waiting for validation, but it s possible I change the code to use DDF file ( to remove the useless "light" entry)

[vishivishy]

Cool, sounds good. I'll look forward to troubleshooting and fixing another tuya device with you someday.. :)

Hi @Mimiix! How have you been? just following up to see if this is getting merged soon..

[Mimiix]

@vishivishy Hi! :) All good here. How about you? Thanks for asking :)

I'll ask manup to merge it, but can't make promises.

[vishivishy]

@Mimiix I'm good too, thanks :)
No worries, thank you for looking into this!
also just one more question, do you know how frequently is the deconz home assistant add-on updated?

[Mimiix]

@vishivishy It gets updated once a new deCONZ stable is out.

[blaz122]

Hi, what to do to have working dimming on those dimmers? Do we just have to wait to be implemented?

If I understood correctly 1 gang and 3 gang moes are already supported?

[Smanar]

It's totaly random, there is new tuya every days, and all look same (and can have same product name), need to compare according the manufacture name and MAC address.

I have the phoscon II and de deconz software on my pi.
The moes 2 gang from ali express installed in my kitchen.
but in the software only getting a light bulb. No dimmer function of two dimmers shown.
I see that on the 2mqtt this _TZE200_e3oitdyu works as it should.
When will this be available on the deconz?
I have a phonscon II on my pi 3
deconz firmware 26720700
version 2.14.00

[Smanar]

For the moment PR are locked to use only DDF #5733

This device can't be added using DDF, so need to improve the DDF core to manage tuya cluster.
