Ecobee 4 with 3 remote sensors. One is set to participate in just the Home comfort setting yet it participates in other comfort settings that I created for early morning. Why would this be?? I have Follow Me disabled and Smart Recovery enabled but no other Eco+ options. This one sensor participates hours before it's supposed to.

As far as I can tell, if the temperature is below the compressor min temperature and such that the aux will be used, the aux heat will always start in stage 2.

I expected it to behave like the heat pump does, where it starts in stage 1 and only goes to stage 2 by some threshold. But it seems like that doesn't work. Setting the Aux thresholds doesn't stop it from starting in stage 2. Aux reverse staging at least ensures it steps down to stage 1, everything left to auto often just leaves it on stage 2 the whole time.

Smart Recovery will actually have it behave correctly. It starts in stage 1 like you'd expect. It's just strange it behaves like this when it works intuitively if the compressor is enabled. For decently cold days where it's < 20 all day and the compressor never is on, I'd rather not have it ever go to stage 2 unless it gets really far behind but it seems ecobee can't do that.

I’ve had a custom app I developed running for years with no problem. In the last couple of days I started running into auth issues. I tried to delete and add back the app hoping that would resolve it. The problem is that it requires a PIN to add back; there doesn’t seem to be a way to generate a new PIN on the existing app, and it appears to no longer be possible to create a new app (and API key / PIN). Docs link goes to 404. Obviously developer program has shut down but I thought with existing API key I should be OK … maybe not? How screwed am I ?

Recently replaced a complete HVAC system, 2200 Sq ft house:

• Bosch IDS 3 Ton Heat Pump/Condenser w/ Bosch 3 Ton Case Coil (BOVB36HDN1M20G/BMAC3036BNTD)
• American Standard/ThermoPride THV Series Oil Furnace
• Honeywell HZ432 Panel
• Aprilaire 700 humidifier (installed on return side, hot water)
• 2 x Ecobee Smart Thermostats w/voice control

Was initially under the impression that the Ecobee could control the heat pump vs oil furnace aux switchover. Installers thought they had set up Ecobee to do so, but it never worked. When they returned they installed a outdoor temp sensor and said HZ432 panel needs to determine switchover. System works fine, but have no reporting capability (w. Beestat) because thermostat doesn't know what heat source is actually running.

Questions:

1. Can the Ecobee thermostat be in charge of controlling the switchover temp with this setup?
2. Would love to also have the thermostats be aware of the humidifier, is there a way for the Ecobee to tie into the existing humidistat controls?

Now despite there being an auto-run ventilation feature there's 1 flaw that there is when you have a Zoned system. The auto run feature is all mixed and all multiple thermostats will chose randomly when to run the ventilation causing wear and tear on your fan from the constant stops and runs. This is Especially true when you have ventilation on at 20 minutes for all thermostats. It would be more viable if all thermostats communicated together to run ventilation at the same time instead of there being a chance where one will finish ventilation just to have another one kick on not even 5/8 minutes apart.

Feature: Create a simple Schedule for consumers to be able to set ventilation at certain times during the day for all Thermostats to follow. If one area is unoccupied that zone will not run Ventilation and will ignore the schedule for that running time but the rest will still run at the same time if occupied.

Don’t recall having this issue last winter. Both the Ecobee and furnace were installed brand new last October. The thermostat claims that it is heating, but I went out to the gas meter and it is not calling for gas. It will only blow room temperate air through the vents via the fan. Tends to hang out around 64° (set to 69 or 70). If I reset the circuit at the breaker it tends to resolve it until the next night. But I can’t have my dog freezing if it happens while I’m at work lol. Any and all help is appreciated.

Need some help or maybe a workaround. I suspect this is a flaw/bug but may just by a lack of understanding. For the record, I have the "Ecobee Lite"

I have the thermostat upstairs, which is typically 6f warmer than the ground floor. My ground floor is slightly lower than outside ground level and has fewer air vents compared to the upper (main) floor of the house. So that's why it typically stays cooler in both summer and winter. Downstairs is also where our bedroom is.

Here's the scenario:

I'm in comfort setting "Home" which only has 1 participating sensor (the thermostat itself), set for heating to 71f.

We like it to be cooler when we sleep, so we have a comfort setting of "Sleep" set for heating to 64f. The only participating sensor is the one in our bedroom (on the ground floor). Our schedule has us set to transition from "Home" to "Sleep" at 11pm, and I have the "Smart Recovery" feature enabled so that ecobee can preemptively make changes ahead of the scheduled comfort settings changes.

At around 10:40pm, it happens to be exactly 71f upstairs where the thermostat is (which is exactly as it is supposed to be) and it happens to be 65f in the bedroom (a little warmer than it should eventually be, but not by much).

Since my next comfort setting kicks in at 11pm, using the bedroom sensor, targeting 64f, what should be happening is ecobee should be letting the house cool down until the bedroom temperature reaches 64f, at which point it should maintain 64f in the bedroom starting at 11pm.

What actually happens at 10:40pm is it somehow decides to average the temperature settings from my thermostat (upstairs) with the bedroom sensor (downstairs) and starts showing the average of 68f on the display of the ecobee, then immediately turns the heat ON to bring that average up to 71f. By the time this finishes, the upstairs temperature is 74f (which is +3 over where it should be for the 'home' comfort setting) and my bedroom is 68f (which is +4 over where I want it for the 'sleep' comfort setting).

I'm not really sure what is going on. I really think this is a logic flaw in smart recovery feature when there is an upcoming comfort setting change that also changes the participating sensors.

I have an Armstrong Air (Allied Air) A96US2V two-stage furnace with an Ecobee 3. As installed by the HVAC technician, the staging was controlled by the furnace, and I wanted to switch that to be controlled by the Ecobee. Can I verify that I did everything right?

I went into the furnace (disconnected from power) and adjusted DIP Switch 1 from ON to OFF. I connected the BROWN wire to the W2 on the terminal strip. At the Ecobee 3, I connected BROWN to W2 (AUX2). I then powered on the furnace.

I then manually told the Ecobee that W2 was now connected. I set staging to MANUAL, set HEAT DIFFERENTIAL to 1.5ºF, and HEAT STAGE 2 TEMP DELTA to 2ºF.

Does this all sound correct, please?

Not sure how this happened, but My ecobee thermostat shows up in Fahrenheit. But the weather forecast on it and on the app shows in centigrade. How do I get them to be the same?

the Built-in radar occupancy sensor is the only difference. it sounds nice in theory but is it worth the upgrade? their sale is running till tomorrow at midnight. thanks for your opinion!

I have two geothermal ACs (upstairs and downstairs), and I set a constant temperature (70 on both) with it always on Home. Smart Away is triggering while I'm sleeping. Away is set to 68 on both. Upstairs is setting 68 when Smart Away triggered, but downstairs is setting 66. So it's freezing and takes forever to get back to temp in the morning. As far as I can tell everything is set exactly the same. What is causing this and how do I fix it?! (Other than setting manual schedules)

Found that my Aux heat max outdoor temp was set at like 55°. So that should be lowered right?

Also read that modern heat pumps can run down into the single digits.

So could I also lower the compressor min outdoor temp? And then set the aux heat max outdoor temp 5° above that?

I am trying to determine if ecobee can do what I am looking for.

I have a boiler for my heating, and a central HVAC AC system. There are currently two thermostats.

Ideally Id like to have two ecobee thermostats where they are linked and when its summer and I turn down the temperature on _either_ of the thermostats, it activates the AC. But in the winter, if I turn up the heat on _either_ thermostat, it will turn on the heat.

I believe ecobee can "link" two thermostats, but I couldnt really determine what that entails.

Guess I will try here since no response from support. Recently my son’s sensor started showing as unoccupied even when my son is sleeping in the room. What appears to be the case is that if it’s unoccupied it’s not impacting the thermostats decision to turn on the heat. So my son’s room goes well below the minimum temperature set but the system does not turn on.

I have the sensors set so that hi sensor is the only participant sensor.

Any ideas?

We had a new Rhem 2-stage heatpump system installed over the summer, I think the aux heat may not be working. Last night was the first really cold night of the season, and it looks like around 3AM the aux heat kicked in, but the temperature in the house kept dropping. At 6am the aux heat was still engaged and the air coming out of the vent was 57f.

I called the service people, but is there something I can check in Ecobee in the meantime?

I have two identical air to air heat pumps (upstairs and downstairs) with a Navien hooked up for auxiliary heat. The downstairs runs more frequently (typically 30 min on, 30-40 min off) because of a lot more windows and doors. The upstairs runs much less frequently, but for some reason it's calling aux heat (red) once or twice a day. The past two nights it's called it one time around midnight, and it called for it again this morning at about 10 am. The heat set point isn't changing and I have both within 1-2 degrees of each other depending on time of day (66-68º).

I understand aux being called for a pump that can't keep up, but it's not cold enough for that and it's not running long enough to struggle (only ran for 30 min before aux) and I think it's odd that the same model pump for the downstairs would run more frequently and sometimes longer and never call for help.

Are there settings I need to double check? Is this a symptom of a brewing issue?

Thanks in advance for any and all ideas!

Any idea why this is happening? Losing WiFi connection? HVAC issue. Ecobee issue or wired wrong? New to using an ecobee and just moved into a house built in 2006 .

I’m checking compatibility on their website and it tells me the wiring selection I put in is uncommon - r g c y o w2 - but when I put the same ones into the nest compatibility checker, they are fine.

For another unit, I put in - Rh w b - and ecobee’s compatibility checker also says it’s uncommon, though it was fine for Nest. In that existing thermostat, it’s a little weird because it’s a blue wire going to the b terminal, so not sure if it was installed wrong, but it seems to be working fine.

I’ve been on hold on chat and phone for a while with ecobee and no one is picking up. Any insights on this? Is it probably fine to order the thermostats?

My first floor is on ecobee. When I renovated the house. I pulled a 5 wires cable to match ecobee. My second floor unfortunately is on nest 3rd gen and 2 pair cable run. Any way to convert that to work with ecobee?

The nest has that WiFi bug where it goes dead and I have to reboot it. When remote, I can’t connect to it

It does not have hold temp. So some times at night it drops to away when I’m sleeping and becomes freezing.

I really don’t want to get another nest but due to cable. I may have to. Any suggestions

Can ecobee door sensor can be used for garage??

I am replacing a very old round two wire Honeywell thermostat with a new Ecolite3

I have swapped out thermostats quite a few times over the years, but never to a smart thermostat.

We only have two wires so I purchased a plug-in 24 V transformer I connected the two wires coming out of the wall to Rh and W and the transformer wires to RC and C

After the thermostat turned on, I got a low-voltage installation error message. I checked all of the connections and tried it two more times all with the same error message.

I used a multimeter to check the voltage coming from the transformer at the thermostat and it was 23.9 V so I would assume that’s close enough to get it to turn on

What else should I check for? This is an inexpensive plug-in transformer from Amazon. I’m wondering if I should get one that plugged in, but allows me to connect to my own wire to use a thicker gauge. The wire that it came with is very very thin and barely fits into the thermostat wire mounting system.

Any help is appreciated. Thank you.

I have an Ecobbee 3 Pro that came with my new system. I would like to adjust the differential for the heat & cool to be either 1 or 1.5. I believe the default is 0.5.

How do I make this change?

I'm new to Ecobee, as I just switched from Nest. I was able to run the fan everyday for an hour on a schedule with Nest. Searching up old threads, it seems that this wasn't possible in the past, but maybe it is available now. However, I believe I have a workaround that will work. I like to run the fan everyday for an hour to circulate the air, remove dust, etc.. Also, this time of day the solar panels should be running the fan for free on most days of the year for us. Here is what I did; let me know if this will work, or if I am overcomplicating things.

Sleep Comfort Mode carries over from night before.

Set a Home Comfort time for early mornings before we leave to work. 5AM-6:30AM (Heat the house)

Set an Away Comfort time for 6:30-10:00AM

Created a new Comfort profile called Fan. Set extremely low heat and high cooling settings (45F and 80F). Set fan from Auto to ON for both Heat and Cool. (Maybe my heat and cooling temps should match my away profile)

Set Fan Comfort time for 10:00AM-11:00AM.

Set Away Comfort time for 11:00AM-5:00PM

Set Home Comfort time for 5:00-11:30PM

Sleep Comfort Time till next morning.

Copy and pasted this day to the rest of the days of the week, Weekends slightly altered.

Did I over think this? Or is this the only way to achieve what I want?
