I added the Tuya component yesterday to get my Eurom E-Convect WiFi working with HA.
As a Eurom branded appliance I used the official Eurom app to control it, this did not work with HA though. Creating a Tuya account did however and I could then re-add the heater in the official Tuya app.
Once HA was restarted the heater was identified and is now working perfectly with automation in HA.
Tuya has a lot or re-branded appliances but they all work with the Tuya app.
