If your furnace supports OpenTherm, you might be interested in my repo for ESPHome: https://github.com/wildekek/esphome-opentherm-templates

My furnace is an old beast

#

No idea what it is or how it works

#

My current thermostat is a Honeywell

#

With an eif control board

#

This looks awesome

#

Not sure if it would work for me though, I've got a dumb thermostat and an old furnace

You could always use ESPHome with a bang-bang controller: https://esphome.io/components/climate/bang_bang.html

I would need a thermostat, since I've also got AC in the loop

#

Please correct me if I'm wrong 😅

#

You can add both heating and cooling devices to 1 bang-bang controller: see heat_action and cool_action

Ahh cool

#

What exactly does a bang bang controller look like?

#

Especially "# Example dual-point configuration entry"

#

As far as hardware goes, depending on the furnace and aircon, two relays could be all you need to hook it up.

Would I be able to keep the original dumb thermostat in place?

#

If not, could I implement a touch screen that could control it
