HA 0.102.3
Ubuntu 16.0.4 venv install as a different user, Python 3.7.4
I have a Mitsubishi heatpump that is being controlled using MQTT. The device I’m using to control the unit handles HA MQTT autodiscovery. I’m located in California, and have set HA’s units to “imperial”:
homeassistant:
unit_system: imperial
The problem is that the temperature data from the unit is in Celsius, but HA is displaying these Celsius values as Fahrenheit values.
I’ve tried setting the unit_of_measurement to “C” and “°C” using a customization, but that doesn’t change anything.
Entity state:

I had been using a custom component for the Mitsubishi heatpumps that, looking through the code, set the temperature_unit of the entity to TEMP_CELSIUS. I guess because of this, even though the data in MQTT is in Celsius, the custom component temperatures are correctly being converted to Fahrenheit.
MQTT:
office/ac {"power":"OFF","mode":"FAN","temperature":23.5,"fan":"3","vane":"AUTO","wideVane":"|"}
office/ac/status {"roomTemperature":24,"operating":false}
office/ac/timers {"mode":"NONE","onMins":0,"onRemainMins":0,"offMins":0,"offRemainMins":0}
Entity state:
hvac_modes: auto,cool,dry,heat,fan_only,off
current_temperature: 75
min_temp: 45
max_temp: 95
target_temp_step: 1
temperature: 74

How do you configure an autodiscovered MQTT climate device to have HA convert the temperature from Celsius to Fahrenheit?
