Bought a "Maxim Smart Plug Socket" on a whim from one of the bargain shops for £6. Appears to be a rebadged Tuya.

Can I get it working with Home Assistant as is? No. May play with the Tuya app later but the Maxim App won't let me connect HA.

Not worried if I can't. This had one specific purpose and I don't need HA for it.
