Can't configure AC

[RobertN82]

I've had my AC setup as a switch for a while but finally getting round to setting it up as an actual AC. I just can't figure out the config.

When HB boots it sets it to C instead of F, and the temp shows 0. When I turn it on the temperature ranges from 149 to 167 degrees. The log continuously pumps out:

[07/07/2023, 12:28:45] [Broadlink RM] [INFO] AC Bedroom onTemperature (-17.77777777777778)

...etc..

Config below... what am I doing wrong? 😄 Am I supposed to do something with temperatureFilePath ?

What are you using as the temperature source - the Broadlink thermometer? Looks like it's pulling the temperature so no need to use temperatureFilePath.

I don't have experience configuring in Fahrenheit but I suspect you need to set the min and max temperatures in Celsius. Try using:

            "minTemperature": 18,
            "maxTemperature": 24,

So after some more reading I realised that I need a temperature sensor. I managed to setup that up successfully through mqtt using the homebridge-mi-hygrothermostat and a sensor. Hooray!

It does still show the crazy temperature range from 149-168.

It also gives me this warning:

[14/07/2023, 11:30:28] [homebridge-broadlink-rm-pro] This plugin generated a warning from the characteristic 'On': Characteristic not in required or optional characteristic section for service Fanv2. Adding anyway.. See https://homebridge.io/w/JtMGR for more info.

Is this because tempSourceUnits is set to C (the sensor only supports C) and the rest of the config is set to F?

I could set it all to C as you suggest, but then it's weird setting the hex codes as they don't quite align:

18.0    64  HEX_COOL_64
??.?    65  HEX_COOL_65
19.0    66  HEX_COOL_66
??.?    67  HEX_COOL_67
20.0    68  HEX_COOL_68
??.?    69  HEX_COOL_69
21.0    70  HEX_COOL_70
??.?    71  HEX_COOL_71
22.0    72  HEX_COOL_72
23.0    73  HEX_COOL_73
??.?    74  HEX_COOL_74
24.0    75  HEX_COOL_75

Experiencing the same thing. Very frustrating. Seems to only work for C.
