Hi. All my heating is in Celsius and I have thermostat devices from the Heatmiser plugin as well as some new zwave Spirit TRVs. When I change the temp of one of these devices in Homekit, for instance from 10 to 20C. The app shows 20C. However indigo shows the actual set temp at 19.8C
Are you doing some conversions to F and back again that maybe are losing some precision? It's only reason why I can think why a different value is sent.
I didn't see anyone raise similar before.
Thanks.
