Mysa Thermostat Controller stuck in Farenheit

I am using the HomeKit integration to manage my Mysa Thermostats. I can change the units on the device from F to C, however this does not have any effect on the Controller, which is stuck in F. I’ve tried reloading the device, but no luck. I imagine this is a bug, but am looking for a workaround. Is there a way for me to edit the device configuration directly? I imagine this is not a very complex change.

Hello IvanLH,

I did this a couple of years ago, but I believe it is still valid.
