Python Plugin: Domoticz-TinyTUYA-Plugin (Cloud)

[Xenomes]

Do you have Bookworm or Trixie?
How are you running Domiticz local or docker?

[DomoticzRob]

Hi all,

New to this forum but in the meantime many years enjoying Domoticz!
I started with Domoticz on my NAS, later to Raspberry PI but now for a couple of years on Windows (2025.1 version) which works for me very well as I'm not such a Linux guy.
My latest hardware connected to Domoticz is a Tuya thermostat which I like very well. The Tuya app is superb and access to the cloud work good.
But my wish is to automatically set a temperature from Domoticz.
So, I installed Python 32 bit V3.10 and of course the TinyTuya plugin.
This was not much of a struggle, Domoticz sees the hardware and my device variables.
The actual temperature is read and within a couple of minutes I see changes of the actual value and set value on my Domoticz.
Note that temperature set value was done on the thermostat or via the Tuya app (see question 1).

Now the questions:
1. When I change the set value from Domoticz, the changed value never reaches the thermostat.
The thermostat keeps it old value.

2: Not always is the actual temperature value "actual". The "Last Seen" value is sometimes way back...

3: Log errors:
I do have some errors:
Error: (JSONtoPython) failed to add item '-1', to list for string.
Error: Tuya: Domoticz.Configuration read failed: <built-in function Configuration> returned a result with an exception set
Error: Tuya: Device read failed: bf0fa6dfdcb9523a1cqgjw

What can possibly go wrong?

Did you put the device on DP instructions? If No, change it as instcucted in de pdf and restart Domoticz and test again. If Yes, can you run the debug_discoverty.py from the tools directory and make a issue on https://github.com/Xenomes/Domoticz-Tin ... gin/issues and add the dump.json file to the issue.

Okay, I test it last night on Trixie indeed the == version where a issue, but the code without == worked. Did you use sudo to install the pip3 modules?
Domoticz is running local as super user. without sudo they are installed under the user and not het root (super user).

Thnx Xenomes,

I created an issue with the error messages in Domoticz log and the dump file.

That is a strange one. requests is part of Tinytuya, and on my three test systems I don't have the error. I have added it to the import of the plugin. Hopefully the error is gone now. Version 2.3.6c

I'm running Python 3.11.2 (main, Apr 28 2025, 14:11:48) [GCC 12.2.0] on linux
Now I remember I did large update of apps on my system few days ago. Something broke this I guess.

The Domoticz Docker container has been updated to a higher release of the distribution. I will test it and fix the code or the requirements guide.

Out of the scope of the plugin:
You need to update your docker installation to the current version.
https://github.com/domoticz/domoticz-docker
put docker-entrypoint.sh in your directory where your customstart.sh is located.
Edit your customstart.sh to remove old lines see the customstart.sh in github.

In the scope:
The plugin needs tinytuya and PyCryptodome for the pip3 installation. Then it should work again.

What do you mean with "Edit your customstart.sh to remove old lines see the customstart.sh in github" ?
I never got installing tinytuya and PyCryptodome using the customstart.sh script.
So I installed all lib's to folder and point my docker to that for python.

The customstart.sh script handles all my package installations, both apt and pip dependencies. When I rebuild the container, everything gets freshly installed. I keep my git clones in a separate Docker shared volume so they persist between rebuilds.

They are not really exciting, the docker-entrypoint.sh is unchanged, and the customstart.sh is only simply modified.
