I got a dehumidifier on aliexpress, but the documentation on the modbus registers seems to be nonexisting.
Reading the first 14 holding registers gives the following values
[524,431,10,50,80,2,1,0,0,0,0,0,522,0]
So far I have found the following
0 = Temperature, but 524 is 22.4c, so must have 30 subtracted?
1 = Humidity, must be divided by 10, so 43.1%
2 = S01, min temperature (activate heater relay)
3 = S02, max temperature (activate fan relay)
4 = S03, max humidity
5 = S04, humidity hysterisis
6 = S05, device address
The rest I am not sure about.
But I am puzzled by the 524 value, having to subtract 30 feels strange, or do I need to somehow convert it?
