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](https://developer.tuya.com/en/docs/iot/authentication-method?id=Ka49gbaxjygox) and [Sign Requests-Tuya IoT Development Platform-Tuya Developer](https://developer.tuya.com/en/docs/iot/singnature?id=Ka43a5mtx1gsc) I managed to get it working in a Postman environment (guide on [developer.tuya.com](http://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. Jeroen ---

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.
