I think it’s supposed to integrate with “Tuya” under “smart life”. I made an account with smart life & can successfully control the switch with the “smart life” app.
How I tried to integrate:
Step 1: I try to integrate the switch into HASS via TUYA & the subcategory smart life (see below snapshots):
Step 2: I then click submit and it says “Success!”.
Step 3: I then click finish, but then there aren’t any devices under Tuya per the snapshot below.
