Temperatures are shown in both 'ºF' and 'ºC' in history graph but calculated at 'ºF'? (it Fixed it self)

ESPHome
1

I’m working on a Esphome project that monitors my hydronic boiler temperatures and adjusts the high limit of the boiler. ( Show your most scary home made automation device )

It works well with the exception that HA displays the sensors from the device in both C and F however it calculates the reading as F.

Displayed as:

And a graph card is shown with only ‘ºF’:

The module config is:

  - platform: dallas

    name: "Boiler in temperature far"

I think I maybe could make a template sensor to fix the display to only show ‘ºF’. But why is HA displaying both ‘ºF’ and ‘ºC’ , but calculates the values as ‘ºF’. even though the device sends out values in ‘ºC’ ?

Hmmm. It’s seems to have sorted it self out.

Now it shows the graphs properly.
