Would like to replace old 2 wire thermostat

[logbuilder]

I have an older Honeywell thermostat. There are only two wires running to the furnace. It would be very difficult to run new wires. I could run AC to the thermostat location pretty easily.

Is there a wifi, insteon, or z-wave thermostat that will work with only 2 wires?

Other ideas?

Oh yeah brother! Just check out the HS store. There are Z-Wave t-stats that run on batteries.
