I have a ‘dump’ thermostat; used nest in the past but not a fan of how it worked back then (i had the v1 in my old house). With Black Friday around the corner i would like to know if the Evohome would be a good fit for my use-case.
To give you an idea of my skill level; I am fairly good at DIY, program and solder my own ESPs, wrote some custom (embedded C) BLE software for it, so connectivity is not really an issue.
- I don’t have hot water downstairs but a Cooker; the only place which uses hot water is my bathroom.
- I prefer to have my home automation complement, but not take over stuff.
I am from the Netherlands; have a fairly new boiler (Remeha Calenta from 5yrs)
My boiler does not have an outdoor sensor for the temperature; i am planning to feed the outside temp using a cloud service at first, followed by my own local measurement. Feeding will probably be done via a to be acquired opentherm gateway, in gateway mode, if possible.
My radiators are not yet 'tuned’
I still have to tune my radiators for optimal flow, but i am not sure if that has benefits still if i already plan to use the evohome, can somebody answer this?
I have floor heating
My entire downstairs has floor-heating, i have no radiators there. The pump is attached to a Sonoff R2 and i am planning to use the temp sensors of the IN and OUT of the manifold to see if the pump has to switch on or not (or, if i can get out of Evohome when the ‘zone’ is activatedi would be using that as second backup, in case my temp sensor fails).
- Would i need a bypass in my system in case i plan to use a valve for downstairs, or…
- Would you split the 9 loops i have downstairs with the motorized valves from Honeywell as well, and e.g. place multiple BLE sensors which will control the downstairs via the local (RF) api?
- Is my assumption correct that, whever coupled with an Hce80, i can also connect my floor pump to that system and have it be controlled that way?
I have a wife
My wife would like to have the bathroom heated in the morning;
- Is my assumption correct that the evohome can configure each knob (if needed) as a seperate zone and that it will know per zone how long the heating time will be? E.g. if i set the bathroom to a temp of 20 degrees at 06:30 that Evohome will ensure (eventually, after learning) that is the case at that point?
I have 3 kids
Knobs will be put in every room upstairs so that my kids can have a warm room when they are old enough to do homework.
- Is my home a good candidate for evohome?
- Would the above described use-cases be possible in my situation?
