I managed to get everything working between my heat pump HVAC unit and my Ecobee when I installed it almost a week ago. When the Ecobee asks for heating it heats and when it asks for cooling it cools. The issue is that the Ecobee does not actually call for the heating or cooling when it should. It's very strange, sometimes it works fine and other times it just wants to sit there and do nothing when it clearly should be adjusting the temperature. It seems like leaving the house and coming back might have some way get re-engaging it because at times I have left with it not wanting to do anything and when I arrive back it's decided that it will do what it's told. This is all very weird and annoying. It should be so much more straight forward once the hard part of figuring out the installation is done but it's actually the complete opposite. Any suggestions out there?

Which thermostat do you recommend which model please?

I'm getting an ecobee premium delivered soon. My power company unenrolled my home from power shift but mentioned that the previous smart schedule will continue until I replace the old smart thermostat. Will installing the ecobee stop the old schedule, or do I need to do anything else to ensure it doesn't follow the same old schedule?

I'm looking to get an Ecobee thermostat premium. The hardware is excellent, but I'm paranoid about it phoning home.

1. Will the thermostat still work if I isolate it to a no-internet VLAN?
2. Can it be controlled via a local-only HomeKit emulator like Homebridge without an API key from Ecobee or internet access?

Thanks!

I recently got a brand new Ecobee thermostat installed. The Smart Sensor that came with it pairs fine. However, the two I bought in a pack separately do not. Even with the sensor right next to the thermostat, it cannot connect. The phone app gets stuck in the "remove tab" step.

For info, I got the sensors a few days before the thermostat and had already pulled the tabs, if that matters. But to get the qr code I had to pull the battery out to see it anyways.

In the last few days, my ecobee 3 is reading the wrong temperature of the room. When I go to the Sensors section in the app or on the Ecobee itself. It is telling me the temperature is 78 degree, even though the room in 67. That is including me using the temperature offset by 10 degrees. I have reset the Ecobee and detached it and reattached it and same issue. It is about 5-6 years old. Any idea how to fix or do I just need a new unit?

I have a Whalen heat pump circa ~2002. Model number is "Whalen vi-a-402-bo", unfortunately there is no literature about it I am able to find online, this is the closest.

It is a single heat pump <> thermostat system. It is a small apartment so nothing fancy.

Our current thermostat is terrible, it is impossible to accurately set temperatures, instead it is a game of "set thermostat, be too hot/cold, adjust thermostat, repeat until comfortable until weather outside changes and do it again".

I also would love to be able to have heat/AC come on before waking up, hence the desire for a smart thermostat. I only want a decent UX (at the moment it is borderline impossible to see what temperature I've set my thermostat to) and basic programmable features.

There seems to be an unused white common wire with 24v, so I think I should be good to power a smart thermostat.

I have three questions: 1) Is there anything obvious/catastrophic I am missing here?

2. How can I verify that the wiring in my heat pump is accurate to the wiring diagram (i.e. the red wire in my heat pump isn't being used as the yellow in the diagram, etc). I have poked around (breaker and heat pump power switch both off) but it's a tight space.

3. Is the fact that this a heat pump an issue?

Hello,

I recently had a multi-zone mitsubishi system installed that aligns with my existing multi-zone boiler. The boiler start/stop and zone valves are currently controlled with ecobee3s. I'd like to control the heat pumps wirelessly via the ecobees in place of the remote controls and accomplish the following sequence to take advantage of the different system efficiencies.

1. When OA temp is below setpoint (adj.) +/- deadband (adj) and there is a call for heat, run the boiler.

2. When OA temp is above setpoint (adj.) +/- deadband (adj) and there is a call for heat, run the heat pump.

3. On a call for cooling, run the heat pump.

Has anyone done this and can recommend a method or integration?

Thanks!

I recently found out I have a multi speed blower motor in my furnace, but my ecobee controls are only on/off so I do not think it is wired up to control the blower speed. What are the advantages of wiring the ecobee to have that kind of control over the fan?

I have a commercial office building with several ecobee3 lite thermostats. My problem is that there are not many windows in the building and my tenants get uncomfortable fairly easily. I allow them control of the thermostat but often times it ends up in combined heat and AC mode with a 5° temperature offset and then they are complaining at me that they can’t adjust the thermostat properly. So for instance, it might call for heat at 67° and call for air-conditioning at 72°.

I’d be fine with simply turning this mode off and I’d also be fine with a smaller offset like two or 3°. Is this an adjustable setting that I can play with?

I have an ecobee3 light thermostat that doesn’t seem to be calling for air conditioning and turning the unit on. I’ve had success before power cycling, and restarting the thermostat but wanted to see if this is something maybe a factory update would fix?

I have two Ecobees, one Premium and one Lite. Every few days, this warning pops up on the Premium. It’s 70° in the house.

Hi folks,

​

I'm about to have a new HVAC system installed, and a cruicial part of that is integration with my smarthome platform(HomeAssistant). I just looked at the ecobee page on the HomeAssistant docs where it says: "As of March 28th, 2024, ecobee is no longer accepting new developer subscriptions, and there is no ETA for when they will be allowed again. Existing developers are not affected." - I just checked the developer portal and sure enough it looks like new developer applications are not accepted.

This leaves me a little frustrated and second guessing whether I should be going with Ecobee(the installers are coming on Thursday so I guess it's a little late now but still). I'm aware that HomeKit is supported, but I don't know if there's a smaller subset of functionality supported through HomeKit. Can someone here who uses HomeKit advise?

Even better - is there word on when people will be able to sign up for a developer account and API key again?

Hey guys, I apologize , this may be a noob question but I cannot seem to make sense of the ecobee settings. I have ecobee premium and one room sensor (office in my case). Follow me is enabled , smart recovery is disabled, and right now both “home” and “office” show up as occupied. First weird thing - the temperature where the thermostat is is 79 degrees (confirmed by another nearby thermometer and the thermostat screen) yet the “home” sensor shows 76 (I would imagine this sensor would be in the main unit and match the units temperature but doesn’t seem to be the case ). Also , I’m absolutely sure it’s not 76 anywhere in the house right now 😆 where did that reading come from ?

Second - the main unit shows 79 degrees , the office sensor shows 81, the temperature setting is set to 78… and my AC is NOT running. If both sensors (both added to the comfort setting) show as occupied which temperature will be taken into account ? And either way, when both are above the setting shouldn’t the HVAC turn on ? I’m sure I’m missing something but in my defense I’m sitting in 81 degree room with no HVAC my brain is melting 😆

Here are some pictures from the configuration:

(Note - the AC otherwise works. If I go and set it manually to anything below 76 it will turn on. I just need to be able to control it with the schedule / app, that was the point of spending so much money on a smart thermostat that’s making me feel dumb 😆)

I like my house to be the same temperature regardless of the season. I'm good with thresholds up and down that I've set to cause the heat or the cool on my heat pump to kick on. But, because I have to set two numbers in the Auto functionality that have to be two degrees apart, it means I have to shift those numbers up or down depending on the season to achieve my desired temp. Or it means I need to stop using the auto feature and just set to Cool or Heat depending on the season. I'd rather just set a single temp and let the thresholds do the work. Is there a technical HVAC reason for this? Or perhaps some existing functionality I've missed the past seven years of owning this thing?

Update Edit: Thanks for all the replies.

I should mention that I love my ecobee and have been a very happy user for over seven years. Hopefully this wasn't seen as another complaint post by someone that hasn't taken the time to understand their system and how an ecobee works within it.

I now understand the issues that overshooting can cause to my suggested functionality. I was a bit blind to that because my system doesn't unintentionally over-cool/heat. I really liked the opposite system lockout idea for a certain period of time to prevent the back and forth.

We like our house to stay between 66-70 degrees all year. Given the current setting abilities, I've struggled to find a set-it-and-forget-it setting to achieve that. Especially in the transitional weeks between seasons.

Just curious, had a Carrier unit for about 12+ years, and recently replaced with a Rheem unit. I'm continuing to use the Ecobee after the install, but I wasn't sure if anything needs to be modified / re-calibrated in the Ecobee settings.

Side question, what's the best way to see how accurate the temp is on the ecobee screen, would putting one of these (i have a few of them) on top help w/ anything or not accurate enough?

Does anyone have any insight?

I have two HVAC units in my home, one for the downstairs and one for the upstairs.

My upstairs thermostat is in the hallway, sensor in my bedroom. I’m looking to move my office to a larger room that sits above the garage, which tends to be a lot cooler during the winter and warmer during the summer.

I’m assuming that adding another sensor specifically for that room will help balance things or will it only try to do so when it senses movement in the room?

I recently changed my schedule by adding a few extra comfort settings. (Avoid AC during peak kWh hours) If you take a look at the schedule in my link below, the air conditioner should not run until the average reading is 78 degrees. However, it keeps running like it's on the home schedule cooling to 75 degrees or less. I disabled "Smart Home/Away" but that's not helping.

The actual thermostat display only shows Home, Away, and Sleep comfort settings. It says I'm on Home. Is it not syncing despite both the app and Ecobee website saying the comfort settings I added are registered. Does anyone know what I am missing?

I've got an ecobee thermostat in my home. I just put another thermostat in my church. Each thermostat is in a different account. How can I work with two accounts on my Android phone? The account at the church will have multiple users.

Yes + side is out towards door. Yes I've tried being directly next to the thermostat while doing the connection process and yes everything is connected to the same wifi network. What I don't understand is it tells me to wait to pull the tab until after I scan the QR code. Okay well I don't have that pull tab as I've removed it the first time I set these up. And also the only QR code I have to scan is behind the battery so it has to be out to scan it lol now how can it find it after scanning if the battery isn't even in it yet? Lmao seems like a pretty stupid feat of engineering if you ask me lol useless time energy and money of mine if you ask me. Almost seems as if they're one time use since I can't reuse them once the original battery goes dead

I've noticed that our A/C might be short cycling. I have a dual-zone system (upstairs+downstairs), two Ecobees, and they were connected using the grouping feature. I checked the portal and I'm guess I'm late to the party about how they removed that feature.

So now I think I have two independent thermostats, each controlling the same A/C unit, each with their own idea of how long the cycles are? I have manual staging set on both of them to identical values -- but is this pointless if there are independent thermostats?

I recently installed the premium stat with three smart sensors. I am not using scheduling or comfort modes, I want to manage my own temperature range. How would I setup the system to use the average of the sensors to determine the indoor temperature, not just use the thermostat temperature? I don't care if a room is occupied or not.
