Thanks for the link, I might need to look into this, it may be able to help me simplify my rather complex setup (I described in another comment) with a BLE temperature sensor in every room that I use to control the Z-Wave TRVs since the temperatures sensed _at_ the TRVs is way off reality due to proximity to the radiator.
