I don’t know if this helped anyone, but plugging a heater into the socket instead of a lamp caused it to register the power and current reading. I think this might be because of the way Tuya Development Platform records each entity? Current and power has step as 1, anything below might not be registered.
I would flash Tuya local if I could but they’re Brilliant Smart Plug 2 which can’t be flashed…maybe one day I’ll transplant the chip with an ESP32
