I have a standing desk (generic OEM model rebranded for the vendor) and I just acquired a device that allows me to integrate and control my desk using Tuya’s Smart Life app. It works very well with the app, but with HA it shows as unsupported.
Here is the diagnostics. I think it explain very well about the capabilities (up, down, stop, memories, etc.). Please let me know if need anyone to test this integration.
