Node-Red and Tuya

[IanIreland]

I have been playing around and managed some local control of Tuya devices.
So far I can turn on and off!

I am using node-red-contrib-tuya-local

With msg.payload = {"set": true, "dps" : 1} I can turn devices on.

I am trying to find the commands to change colour or scene in a Tuya bulb but so far with no success!

Has anybody had success with commands other than on and off?

I haven't looked at it yet, but I saw there's a Tuya Local integration for Home Assistant that might shed some light on other commands.

If you need help reading the Python code just let me know.

Apparently you would need to determine the DPS setting to change to set the colour. Try adding an Inject node as set below. In the contrib's Issues it is suggested this may work. The biggest difference is that they appear to use JSON to set the values while the node as shown below is adding them as individual items. Done mostly so you can see what is being set and maybe change an individual item easier. THis should set DPS 20 to True and 24 to '00da03e803e8'

Inject Node to Import:

[{"id":"5953c975c9b8758c","type":"inject","z":"a7065ccc9d946145","name":"","props":[{"p":"payload.multiple","v":"true","vt":"bool"},{"p":"payload.data.20","v":"true","vt":"bool"},{"p":"payload.data.24","v":"00da03e803e8","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payloadType":"str","x":260,"y":400,"wires":[["bd5db63f819b2893"]]}]

Additionally, this MAY work to set the light to 50% brightness and full red colour:

I found these from someone setting an Arlec RGB + CCT bulb (Tuya Smart Life compatible) via a different contrib. There are many more settings there for different colors and brightness levels.

That one didn't work :-(

This one didn't work either. I have chores to do now but will play some more when I have time. Thanks for helping.
