[App] Eurotronic Technology App (Stable: v3.0.1)

I am having a weird issue and I am not sure where it is resulting from.

I am using an Aeotec Multisensor to measure the room temperature. I have an open kitchen / living room with 2 radiators which have each a Spirit installed. Even when I send the room temp to the Spirits it doesn’t seem like making any impact and they don’t react at all.

A room temperature is send to those devices but it doesn’t seem to reflect in the readings, at all. Am I misunderstanding how it is supposed to work or is it a bug?
