Getting a new thermostat soon, and would like zone control at some point (although not straight away). I'm quite keen to avoid motorised TRVs in bedrooms though as I'm a light sleeper and I've heard they can be noisy.
Is there some kind of (quieter) inline valve that can control zones, and integrated into some app based operation? I'll be having some re-plumbing done at some point, so they could be installed then. Not fussed about voice control guff.
