The user of this system (who is not me) does not have a smartphone or
tablet and isn't interested in learning how to use one.  That rules out any
app-based solutions.  Apps are also brittle - will they still be there in
5-10 years time, will they still work the same, or will you wake up one day
and find they've updated it to something that's moved everything around and
you are now cold until you've figured out how it all works?

An app may have a place for add-on features like controlling it when away
from home (if that's a thing you care about), but life support functions
(which is what heating is at the end of the day) should not depend on a
fragile tech stack.
