What does 3 remote sensors help with if you have just one controller?
I can understand the sensors helping if you have 3 zones and 3 controllers, but with 1 main unit, if you set one room to 70 another room to 72 and another room to 65, won't the thermostat turn off whenever the lowest temperature is reached, if the 65 is reached, it would turn off the heat, other rooms will never get to 70 or 72, right?

Also this requires add'l wire from boiler, so it won't work like Nest E.

I bought this black friday from costco. With the three sensors. I use the sensors two different ways. One I can see on my phone and also ask alexa what the temps are in 4 spots in my house (thermostat is one spot). I can also have the thermostat adjust the heat (or a/c) to run/shutoff according to one area of the house. Like at night I have the temp set for 68 in the bedroom. Doesn't matter what the livingroom temp is where the tstat is, the heat will run and maintain my bedroom temperature. Yes that might make some areas of the house hotter or colder, but i only care about where I'm sleeping for the night.

Then during the day I have it set for an average temp across all the rooms, instead of just where the thermostate is set.

So for your question, you can have the thermostat set to any room with a sensor.


Needs 24v power. If you don't have central air hooked up, then you can just add a 24 v transformer to power the tstat. Would cost you like $20 if you know how to wire it. If you are issues running the 24v wires to the tstat there is an adapter for another $40 i think so no wires have to be run in the walls.

Nice! Been waiting for this for a bit, after missing the last $180 deal. Seems like Costco run this deal kinda often.
Best price for echbee3 + 3 sensor seems to be $170 during last Black Friday.

You can choose to average the temp readings for different rooms or selectively choose which readings to utilize for regulating heating/cooling depending on the time of day.

Anyone know if this will work for a boiler system with different heating zones? For example, I have 5 different zones with 5 different T stats right now. Can I essentially get this and replace 4 of them with the Ecobee + 3 sensors?

Which means that all rooms are still being heated/cooled.

Can someone help me with my home setup. I have 4 zone heat and 2 zone cooling at my home. In total I have 5 dumb thermostats. How many smart ones I need to buy at minimum (I am fine with any brand) ? I want to spend the least amount of money to upgrade to smart thermostats.

Unfortunately, I have a similar setup at my house 6 zone heat, 1 zone AC. If I wanted to do all the zones of heat, it would be 7 total thermostats.

Instead I just replaced 2 of the heating zones and the AC. So 3 smart thermostats.

So that means I need 1 thermostat per zone. Let me then look for cheaper options

Ditto. I nearly bought at $180 last time but first had to make sure I could run a C-wire. By the time I figured I could, it was back up to $200. I'd been checking Costco occasionally and was glad to see it dropped back down.

I had even set up a deal alert for "ecobee" but it didn't trigger.. perhaps because the title says "Ecobee3" and SD doesn't recognize that as a match.

When I went to my store in detroit they did have them. I am not sure if they lowered the price on them or not.

That's not going to be efficient, I think 1 remote sensor is enough, just move it to the room you are staying and that's all.
