The LEDVANCE lineup is great collection of lights.
They are fairly priced, and of good quality.
LEDVANCE is based on Tuya, but LEDVANCE will not open up to the Tuya platform.
They will however very much like to have their stuff integrated into Home Assistant, their problem is that they don’t have the manpower available
They have worked together with SmartThings and Homey, and the SmartThings integration has launched (cloud based) which can be used to integrate it into Home Assistant in a weird and wonderfull way: LEDVANCE integration - this is how to do it as per 03/22
Homey will be launched shortly, and that integration has been done by Homey, in cooporation with LEDVANCE.
Home Assistant can’t be left behind here, it is too good a collection of lights to not have an integration diretcly to LEDVANCE, hopefully local, but secondary via the cloud.
So my request is that you create a local integration to the LEDVANCE lights. If need be, I can put you in contact with the proper people at LEDVANCE.
