Need some help with Tuya API that requires signature authentication

[jeroenvano]

Hi all, not sure where to begin but I need some help from the community (you)

I recently bought myself a Tuya light (powered by a led smart controller) that I would like to control with some flow commands in Homey (e.g. power on/off, color, brightness)

The new light is not supported by the already exsiting “Tuya apps” but is able to be controlled by the Tuya API.
Sending a HTTP post command is what I have done before but Tuya requires authentication through a singnature. Please see Authentication Method-Tuya IoT Development Platform-Tuya Developer and Sign Requests-Tuya IoT Development Platform-Tuya Developer

I managed to get it working in a Postman environment (guide on developer.tuya.com) but struggle now to understand how to replicate and build this with Homey.
I have no developer background, all knowledge that I have build so far is by try on error.
Acctually I am already proud that I got as far as I am today

My questions to you:

1. is it possible to get the Tuya API’s working with Sign Requests in a flow?
2. does the “Get access_token with simple mode” need to be build in a Homeyscript before the API is triggered?

Any guidance is welcome,
Thanks for making the time.

When adding the device doesn’t work, try this neat section of the app. Howto: -With the flow below, you’ll “listen” to event messages of your devices; In this example a message of the ‘text’ type, which will return text, numeric and yes/no values. This way, when you trigger the device you want to control from the Tuya Smart mobile app (Google store / Apple store), or when you just activate a sensor, you’ll catch the device ID, function name and function value events, which you’ll need to tr…

I was able to add the light in the experimental version of the app. Switching on/off works and also setting the color. Setting dim level is not yet supported but for now the app is working. Thanks again!

Thanks, took me a while but am now able to set a color with a dim level. Thanks again for your guidance.
