I concur with you Dan - it doesn't take a lot to completely automate it with
ECS and simple sensors and hardware. Do you leave your old fashioned
"manual" thermostat connected and set to a low heating temp as a failsafe,
in case the computer fails for some reason?

Up here in the North (Minnesota, or anywhere with freezing temps) there's
that risk of freezing water pipes - so it's always good to use a "belt &
suspenders" approach. Sorry, it's the engineer in me,,,

You can use 3 relays on any basic controller like an Ocelot and throw away
your thermostat entirely or just turn it off and leave it connected.  The
three relays make heat, fan, and cool.  The HVAC units even make their own
24v for their relays so all you need is dry contact relays, no power supply.

I have installed temperature sensors in each room and control my upstairs
and downstairs HVAC units seperately.  The temps get averaged for an
upstairs and a downstairs average that set the HVAC units.  When no one is
home, it adjusts to a an away temperature goal.  When we are asleep it
adjusts to an asleep temperature and only pays attention to rooms where
people are sleeping.  When someone comes home, the house knows before we
even open the door and changes the temps and start heating or cooling the
house from the away adjustment.  Works great!
