  • I got right down the rabbit hole on this and ended up with a Wiser by Drayton as it should stick to schedule even if the internet goes down. A lot of the others seem to need wifi to work properly.

    I was also looking at one that worked properly with the right boiler protocol for controlling modulation via Opentherm but lost the will to live
