I've had an ecobee premium for a few weeks now. It's getting colder (finally), and I'm not sure how to understand something weird that happened this morning:

- My Thermostat started reading a temperature of 75 in its room (the smart sensor elsewhere was reading 65, making the average 70)

- When the smart sensor registered as unoccupied, ecobee put on the air conditioning to cool down the occupied area near the thermostat

- It does not feel like 75 in this part of the house. I checked ecobee and it was showing the temperature going up to 80 in the thermostat's temp sensor.

- I unplugged the ecobee from the wall, waited a few seconds, and plugged it back in (thought maybe it was overheating internally). ecobee thermostat's temperature sensor reads back at 75.

It is hi 40s/low 50s outside, so I can't understand why air conditioning would be needed. I enabled eco+ because I got the thermostat for smart temp regulation. It says low humidity is affecting the temp, but it feels cold in the house.

I checked the Home IQ section and heat was coming on overnight, so this is mystifying me.

The added twist is that when I look at the temp readings in the home app (where ecobee shows up as a temp sensor with my HomePods, the ecobee shows the room temperature is 65 while the ecobee app says the room is 75! HomeKit also says that my desired temperature range is different that the ecobee is set to (1 degree lower at both edges).

I set the ecobee to my usual "Home" temp range in the Home app, which my thermostat is now treating like a temporary override.

What is going on here? What accounts for these weird discrepancies? Is eco+ really doing the right thing?

The problem I've noticed is that when I control the fan with Google Assistant, there is a "hold" set on my Ecobee3 even after I ask GA to turn the fan off. This is problematic because I believe this residual hold (which isn't really doing anything) is preventing my Smart Recovery from working.

Steps:

1. Make sure there are no active holds
2. "Hey google, turn on the fan on ecobee"
3. "Hey google, turn off the fan on ecobee"

At this point, the thermostat reads "holding", which won't go away until I manually press the X in the hold bubble.

It seems like a bug or poor design, that when I use GA to turn on/off the fan, it creates a hold which affects smart recovery unless I manually go in and cancel that hold.

Perhaps it's explained by the hold documentation, but the wording is specific to temperature changes:

Any temperature changes made via a third-party integration such as Alexa, HomeKit, Samsung SmartThings, or Google Assistant will also set the ecobee into a Hold.

Also of interest:

• I can't reproduce this in any way by using the Android app, because the only way to turn off the fan after turning it on from the app is to cancel the hold
• On the web app or the thermostat, I can cause the problem by togging the fan to On, then back to Auto (this On/Auto toggle is not in the Android app)

The Alexa feature is terrible in my ecobee. Has anyone else seen this problem and if so how have you been able to cure it?

Above is my current setup. Bought an ecobee because I would like to have my tStat control my air exchanger (HRV) and aprilaire humidifier. From what I read, ecobee premium can do this.

I know about electrical, but only some about tstats. Running into some complications:

• Since moving in, my aprilaire humidifier hasn't worked. It's old, and I assumed I'd have to replace it. But now I see that the white wire seems to go no where. Is that why? Should it be hooked up to the furnace?

• the A/C unit seems to have white wire go to furnace's COM, and red wire somewhere else ... I don't know where but it goes must be the same place the other wire goes that's connected to the furnace 'Y'.

• the six strand wire from the furnace to the tStat actually has the brown coming from a separate HUM connection and blue not connected to furnace... And on the tStat end they separate and the blue+brown go to humidity control panel and the other 4 to the tStat (tStat and humidity control panel are right next to each other).

Because of this funky setup, following the ecobee setup guide doesn't seem to have sufficient ability to address my situation.

I think I may know how to proceed, but am not 100% sure. Can anyone recommend certain site / doc for providing needed info?

I just installed the ecobee3 lite after having a back Honeywell for like 10 years.. however, the ac kicks on then shuts off after a minute. Repeats. Doesn’t cool my home!

That was my old wiring. Can someone confirm where it goes in the ecobee so I can verify I picked the right choices haha!!

My app suddenly quit working another ago. I have uninstalled, rebooted and reinstalled so many times I've lost count. It asks me to sign in, sends me a code to enter, and when I do that it returns to sign in screen. Over and over again. I see posts about have various problems but nothing similar to my issue. Any suggestions? Thanks!

Will i be able to use the ecobee premium with these wires?

How do I set this? I don’t use auto mode.

Beestat keeps showing breaks in my trends, my wifi connection is solid and other devices I have connected don't have issues.

I know it does not affect operation of the device but just curious

I'm switching from a very old Honeywell thermostat that had two different schedules with temp. settings depending on if the thermostat was in Heat or Cool mode.

- i.e., if the thermostat was in Heat mode - it would heat to 22 C at 7am, go down to 21 C at 7pm, then 20 C at 11pm. if the thermostat was in cool mode - it would cool to 23 at 7am, go down to 22 C at 7pm, then 21 C at 11pm.

With the ecobee 3 lite - I can't seem to find those same options. I can set a schedule a single schedule, but I don't see the option to set different temps for whether it's heating or cooling.

Any ideas (I tried searching, but couldn't find anything similar to my above question)

It's an oil burning home with just heat, we have no central air. I cannot even find where the thermostat wires go. The setup in the basement is one I've not seen before. Looks like an oil burner that's connected to the oil tank and there's a water line running into that.

Would the Ecobee Premium work if I just plugged in a 24v transformer wall plug, wired it to the thermostat along with the existing two wires?

We got the ecobee enhanced thermostat in June. It's been working great. Summer stayed relatively cool and we like the setup of it. When it gets chilly, the heat has been good too.

Today it got a little warm outside so I turned on the cool and it started getting hotter instead of cooler. The registers were blowing hot air instead of cool air.

How do I fix this?

I have no idea how to deal with this Ecobee the local Carrier dealer installed. Eco+ is off. Has 2 stage heat. This morning it was 65F in the house, the Ecobee was showing 65F to 66F as the current temperature, and was showing heat was set to come on (.5F) below 68F. I played with the setting and turned everything auto off I could that would have affected it, and the heat finally came on at stage 2 and cooked us. That never happened with the old Carrier system, stage 1 always came on for a few minutes first. Here is the kicker - looking at the ecobee stat page online, the stat page shows the Ecobee thermostat was reporting that it was 68F in the house at the same time the thermostat itself was showing 65F to 66F on its face as the present temperature, so the right and left hand don't seem to work together. I called Ecobee support and sat on hold for an hour. All I got was a recording. I decided not to leave my number because other posts say they never call back. I wish to God I had never bought this Carrier that came with this Ecobee.

EDIT: Solution found. When I spliced the new wire into the solid copper wire and used a twist nut, the twist nut broke the copper. Pulled out my soldering iron, fused it together, put the nut on, and its working perfectly fine now.

So i'm trying to make my gas fireplace "smart" and using the below adapter with my ecobee. A handfull of reviews have said it works, but im having no luck. Any help?

Fire place (Red/White wires)-> to relay (Red/white wires)

Relay (orange/brown wires)-> Orange to W1, Brown spliced with 24v transformer to C

Transformer-> To RC

It is roughly a 50ft run. I connected the 50ft of wire to the red/white wires at the fire place, then tapped them together and it turned it on. So theres enough signal there to turn it on. The eco bee DOES turn on and does detect wires in the W1 C and RC. The problem is the ecobee will NOT turn the fireplace on even if i manually tell it to turn on.

Venstar ACC0436 2-Wire Kit for all 24VAC Thermostats - Programmable Household Thermostats - Amazon.com

What is lower left icon for? The other 3 do something when you push them. The one on the left doesn't do anything when you push it and it always shows 72 even when neither the actual temperature nor desired temperature are 72. (Ecobee lite 3)

Hey all. Just got the premium and ran into an issue with my existing wiring while using the PEK. My "C" slot on my HVAC panel is already in use by my humidifier. While it would be cool to be able to control the Humidifier with the ecobee, my concern right now is just getting everything functional. How might I correct this wiring?

It gets a little confusing, because the wire from the thermostate terminates inside the HVAC and then is connected to a different wire (and colors) with wire nuts.

Thermostat: 4 wires - G, W, Y (blue wire color), R
Humidifier: C (white wire color), R
HVAC: W1, R, G, B/C (blue wire color), Y1

C/White wire from humidifier spliced to blue wire going to B/C on HVAC.
Y/Blue wire from thermostat + R from Humidifier spliced to Y1 on HVAC.

Hopefully the pics help...so how would i go about getting the ecobee pek working with all of this? Thank you so much for your help.

I don't have a C wire on the thermostat outlet. I am trying to install the common wire adapter in the furnace and am confused by the multiple wires going in each slot. Here is the photo of the furnace wiring.

I have an HRV and humidifier.
HRV's green wire is interlocked with that of the thermostat.

I understand how to change the temperature threshold on the wall thermostat itself. However i don’t see a option to adjust the threshold on a stand alone room temperature sensor. Its like two degrees off, is it even possible to change the threshold on them or should I try and return for a new one.

Every winter, when it's freezing cold outside, I have this issue where my Ecobee won’t start the heating system until about 8 AM, even though it’s 30 degrees out. It’s like it just decides to stay off until then. I’ve had several HVAC techs inspect the system, and they all say everything’s fine, but this still keeps happening.

Has anyone experienced this or have any advice on what could be causing it? Any help would be appreciated. Thanks in advance!

Hi, I have a ecobee controller with a system in rent apartment. AC runs fine in the summer, but the heat is not working properly.

Start from off mode, Once I turn on the heat mode, hot air will start blowing until reaches the tempreture. Then the fan keeps running but instead its cold air. The heat will not turn on again even drop 5 degress below the setting. Needs to set off and wait for a while then put back to heat on ecobee for another round of hot air.

Apartment guy knows nothing, even changed a ecobee.

It seems that on several occasions certain options I turned off came back on. For example the heat/humidity option under the eco+ as well as other eco + options. Call customer service and they gave me a run around to plug the hole at the thermostat which didn’t correct anything. Or blamed a sensor which in fact ok. Is there a way for a home owner to determine if the thermostat has failed? Is there a real time site to get info if ecobee ‘s software is screwed up? Something is going on and customer service is playing it “cute”.

I recently had to replace my old HVAC system with a brand new one. In order to maximize energy rebates, I went with a Carrier heat pump combo with an ecobee3 lite.

While the system works pretty well - beyond a giant hole the contractor hasn't repaired in the return duct after inspection, and some initial refrigerant charge issues - I am having to constantly override the ecobee.

I work nights for a company in Germany, and sometimes days in order to attend American meetings, so I'm living a variable sleep schedule throughout the week. I am therefore constantly having to switch the ecobee out of Sleep so I can get a few hours of heat, and then having to put it back to Sleep when I go down to bed. It'll sometimes drop out of the manually set mode after a schedule mode change.

Question starts here: Is there a way to tell the ecobee to not follow any schedule at all and just use whatever mode I last set it with?

Want to make sure I'm not missing something before I order a new one.

Ecobee 3 (not lite). Boots up, shows it's calling for heat and the blower on the furnace comes on, but the burners never light. However, if I pull the ecobee off the wall, disconnect R and W and jumper them, burners fire just fine.

It was working, then it wasn't, no changes. I went through reconfigure just to be sure and everything is correct. Anything else I should try (maybe factory reset) before I order a new one?

Edit to Add: what model should I order if I buy a new one? I have remote sensors around the house I'd like to reuse and I'm running one Accessory (Humidifier) so it needs one ACC terminal.
