I’ll hope i get slammed with people with experience in one or another but i couldn’t find an exact answer on Google so here goes;
What i want to achieve:
- Zone heating in my entire house, i have floor heating downstairs.
- Open window functionality (i already have this setup for my shutters)
- Revert temperature that was set manually either immediately (kids playing with it) or after ‘x’ hours.
- Any automation i add should complement, not take over the system.
- Something that works locally, without any form of subscriptions, since i am sure i can add that and more functionality myself.
Both Tado and Honeywell tick all these boxes (with more or less budget).
- For Honeywell you would need the nanoCUL with firmware to be able to control it locally; otherwise you are dependent on the Honeywell Cloud API and face delays.
- For Tado you would depend on homekit to be able to control it locally; otherwise you are dependent on the Tado cloud.
I think it boils down to the ‘learn’ factor of the thermostats. For example my open questions are:
- Can you assign (for both products) a radiator knob which is in a different room to the main controller which is in another room? This would apply to my floor heating which is under the stairs, which i want to control using the ‘main controller’ which sits in the living room.
- I have read that the Tado takes outside temperature into account to determine heating needs. Is my assumption correct that i then don’t need an outside temperature sensor on my boiler?
- How is the self-learning from Tado compared to the self-learning from Honeywell (if anybody can answer this at all)
One more question i have for the TADO users; if you have this connected via homekit, and you change a radiator valve manually, are you able to detect this (i assume a state changed event is fired from home assistant) and that you also should be able to revert it immediately, right?
