I read Replacing a Honeywell Thermostat with a remote thermostat, but the question/answer there doesn't quite fit my need.

I have a thermostat wired into the wall, but it's not in a good place. I don't want to rewire anything. Instead, what I want is a thermostat on the wall with a remote I can place wherever I want, and it signals back to control the heat. The remote just needs to sense the temperature, and be able to set a set point (although if this needed to be set on the wired wall unit, I'm okay with that).

Does this exist? I can't seem to find examples, and the search terms I use all come back with Nest or other smart thermostats, which is not what I want.

I did find an example of a two-piece unit, but one was an outlet that was switched, for controlling a space heater or the like. I might even be able to modify this to work in my application, but I'd rather go with something off-the-shelf.

  • I own an EcoBee thermostat with wireless temperature sensors. It works great: keeps the front room cool during the morning sun beating on the windows, and keeps the back room cool during the afternoon son.

    I don't mind that this question was closed, but it was more about what kinds of options/technologies are available in general, not any particular product recommendation.

  • In general: Yes, available. Radio links of various kinds are the standard technology. Home-automation sensors and a HA-controllable thermostat would be another approach, requiring more setup but giving you more space for custom programming. Shop around, and come back if you have specific questions about particular technology options. "What kinds" is too fuzzy to answer usefully.

The first thing that came to mind (I don't have one, but I have read plenty about it) is Nest. Sure enough, there is the Nest Temperature Sensor . Little disc that you stick where you want to monitor the temperature. No display or controls. Monitored by the main Nest. $39 each, less in quantity. If you already have a Nest then this definitely makes sense. If you don't, well Nest is not the cheapest thermostat around, so you have to look at the full cost of switching.

A more basic solution, logically, is to not get as fancy as a Nest and simply have a remote sensor that the thermostat always follows (Nest lets you have the temperature adjust to different sensors at different times of the day). But to do that you need (minimum) a transmitter in the remote sensor and a receiver in the base unit, and since the typical ordinary thermostat has no radio at all, that is not something a typical "ordinary" thermostat will support because of the extra cost. So other "smart" thermostats (anything that supports WiFi access) are likely to do something like the Nest does, but more basic thermostats probably not.

Another example, the Vision Pro 8000 (click image for larger view):

has a $13 remote:


Basically, pick a system of thermostat + remote based on your needs, budget and other features.
