Not a question or a complaint. Just an observation and FYI about how inaccurate the actual thermostat is. It generates its own heat (processor, WiFi, display) and can't dissipate it so it could be 3-5 degrees higher than actual temperature.

Ecobee should just include sensors by default with instructions to mount one near the thermostat but not so close to pick up it's heat.

Yes, you can also adjust the temperature offset but that is static so it could still be inaccurate since the heat that Ecobee generates can fluctuate.

A few years ago I had my Ecobee setup perfect that when everyone left the house Homekit would kick my thermostat into away mode. It seems somewhere along the line Away mode no longer works and I have been just using Heat/AC at a manual temp when people leave the house as a temporary "band aid".

My question, is there ANY way to utilize the away function in Homekit?

Hello, I have a house with multiple HVAC systems:

A boiler in the basement has two zones for main floor and upstairs floor.

A central AC in the attic has one zone for the main floor and upstairs floor.

A furnace in the basement has one zone for heat and AC for the finished basement.

I replaced the prior "dumb" thermostat that controlled the whole house AC and main floor heating that was in the family room with an Ecobee a few years ago.

Recently the ancient "dumb" thermostat in the bedroom that only controls the upstairs heating broke. It is a Honeywell 97-4730 Rev A.

Looking at the wiring, I saw an unused wire in the wall. I checked with a multimeter and it drew 27 volts between the wire and the R wire, so I believe that is an unused C wire.

In the Honeywell, there are wires plugged into R, W, and Rc. There is no jumper wire.

The new Ecobee Enhanced I bought says the wire combination is not compatible. Is this because there is an Rc but no Y? The thermostat does not power AC so why is there an Rc? Can I cap off the Rc and only use R, Y, and C?

Thank you for your help.

I press eco+ but it does not say.

If the fan is on "Indefinite On," how do you turn that off?

I don't want to turn everything off... just want to go from "Indefinite On" to Auto.

Have tried the app and the wall thermostat but nothing works other than shutting everything off and leaving it off:

• When I switch it from "Indefinite On" to Auto, the setting doesn't save so that doesn't work.
• If I switch the timer from Indefinite to 15min, the timer runs for 15min, and then it goes back to Indefinite On.
• If I turn the system fully off (ie, turn off "Cooling" which is not what I want) and then turn it back on after 10-15 sec, the fan comes back on in Indefinite mode. (To clarify... I'm *not* turning it off mid cycle. I am turning it "off" when Cooling mode is on but A/C is *not* running and only the fan is running.)
• If I turn Cooling "off" for 5-10 min and then turn it back on then the fan mode will be back in Auto but surely turning the whole system off for 5-10min can't be the only to get it out of Indefinite Mode? That would be silly. (Same thing here... I'm *not* turning it off mid AC cycle, I'm only turning it "off" when AC is already *not* running and *only* the fan is running.)

It's a single thermostat set up with the Smart Thermostat Enhanced (version 4.10.8.256). Only paired with one app. Under system settings, the minimum run time for the fan is 0min/hour so that wouldn't be a factor.

I'm a new Ecobee user and this is driving me bonkers. How is this supposed to work?

I've been using the app to control the temp for several months without a problem. All of a sudden (it seems) it has stopped working. I have a notice that 'eco+ is on' where the temp is set. If I try to change it (up or down) it pops up a message 'Adjusting for humidity eco+ is using the humidity to lower energy consumption and keep you comfortable.' My options with that dialog are 'Stop eco+ for the day' and 'Cancel'. If I try to stop for the day I get a red error 'Sorry we're unable to make any changes due to server connection issues. Please try again later'

I can turn eco+ off on the general settings, but it still shows as on with the temperature. I cant change the temp at all without that error and have to go to the thermostat and manually adjust. Which works fine.

Any suggestions?

I’ve been having this issue a lot lately. My ecobee is making my AC cool even though the temperature is already at or below the target for the current setting. Any idea what’s going on here?
