Any indication on when smartthings will support govee products?
It’s not a question of smartthings supporting Govee products: it’s a question of when Govee will add a smartthings integration, so you need to be asking them.
Beginning last year, smartthings published their API, so now it is up to the device manufacturers to create and maintain their own integrations if they want to provide one.
You might also ask Govee if they intend to offer Matter integration. That might eventually be another possibility.
I’d say Matter is your best bet at this point. The Govee M1 2 meter and the desk light will support matter. It matter doesn’t expose any of Govee’s preset scenes, so integration will be somewhat restricted to “normal” light controls like on/off, dimmer, and color.
