I'm running HomeAssistant and I've tried the native integration, which works fine but is missing power consumption, or there's a HACS-based integration, that is a bit painful to set up, is able to see power consumption, but cannot enable sleep mode... So it's a bit of a hit and miss with either of those. Will take a look at the ESP variant, thank you.

Edit:

Looks like the ESP32 project is mostly tailored for hard-wired installations, but I just have a couple of floor units...
