Xiaomi Air Purifier 4 Lite (zhimi.airp.rma2) support

[gvillo]

Hi! I was wondering if it supports zhimi.airp.rma2 (https://home.miot-spec.com/s/zhimi.airp.rma2), I don't know exactly what are the differences with the supported rmb1

There are small difference between the two models. You can compare the JSONs with the specs of the two models and see the differences.

@kyutov Do you maybe know where I can see which revision my device is after flashing ESPHome? I flashed the device straight without checking beforehand. Just asking in case it is the zhimi.airp.rma2 revision I could then confirm that it works with the zhimi.airp.rmb1.yaml config.

Yeah, there're some property differences, so that one needs its own config.
If you have a backup of the vendor fw, you should find the model as string in there

@dhewg Thank you, yes I was able to find the ot_config.psm_modelzhimi.airp.rmb1 string in the backup of the original firmware. So I was lucky to have the right device for the already existing ESPHome configuration.
