Best Wi-Fi Thermostat Used For Only Remote Operation

Alan (California Radiant) Forbes

The owner doesn’t need a Nest; learning feature not wanted. Since they are often out of town, they just want the function of turning the heating on remotely.

Also, there's only two wires running to the thermostats in this house. I've managed a work-around previously on Nest stats by jumpering the "C" terminal with the "W" terminal on the zone valve control which will power up the thermostat during an "off" cycle. Ideally, this will work on another brand of stat.

Maybe… sometimes… I'd sure want a more robust power supply…

I’ve been using Ecobee in my places, super simple to set up and operate, good support and training videos

I would follow their advice for 2 wire applications

Honeywell RedLink has a 2 wire WiFi thermostat that uses an interface.

Almost. The 8000 series RedLINK wireless models can be powered over 2 wires & talks to an equipment module over RedLINK, but they'll need a RedLINK to wired Ethernet gateway to get to the internet. This setup works very well.

There is a 8000 WiFi model—but it doesn't have RedLINK, so it's wired as normal (and no remote sensors).

IIRC the 9000 series is always a RedLINK equipment module and two power wires, but I don't have much experience with these.
