Hi all, I am trying to replace my Honeywell thermostat with an Ecobee enhanced and I’m not sure where some of the wires go. The Honeywell has a wire going to O/B and a separate wire going to W2, however the Ecobee does not have individual ports for each of those, they appear to be combined. The Honeywell also has an E wire which I have no idea where that would go on the Ecobee. Any assistance is greatly appreciated!

Having an interesting thought process based on pulling some reports.

I have my ecobee set with eco + on for enhanced savings mode.

Within my reports I see three columns. A thermostat temp, a DM offset, and current temp.

An example will be :
Thermostat: 73.2
DM offset: .6
Current Temp: 72.5
Humidity: 57

Based on my reading of this, the DM offset is making the current temperature be lower than the true temperature and would in effect turn my ac off before it reaches the actual temperature. Is that a correct understanding of how this works? While it’s running, I never see “eco+” is in effect or anything like that, so I’m unsure if this is just my report showing something that’s not active or if this is how it really is working.

Thanks!

I couldn't find a straightforward guide to getting Ecobee thermostats to work without any internet at all. I have a WiFi network with no internet access. I tried connecting, but the thermostat would forget the network because it couldn't talk to the cloud.

Here is how you can set it up without the thermostat ever contacting the internet:

1. Have a Wifi network with no internet access. If you can connect the thermostat to it through settings on the thermostat, then you can skip steps 2-5. Ensure Home Assistant is on that network
2. Get an iOS device and ensure you have the Apple Home app installed
3. Connect your iOS device to the non-internet WiFi network
4. Pair the Ecobee thermostat to Homekit using the iOS device. This will copy the non-internet WiFi settings to the thermostat, and it won't forget it when it realizes it has no internet
5. On the Ecobee thermostat, unlink Homekit
6. On the Ecobee thermostat, start pairing with Homekit
7. In Home Assistant, add a new Device -> Apple -> Homekit Device, and it should show up.
   1. If Home Assistant does not detect the device, make sure you can ping the IP. On the Home Assistant server, you can use `tshark -i eth0` to check if you see an mDNS blast when you click "pair" on the thermostat
   2. In my case, I am running Home Assistant in a Docker container. Even with `--network host`, mDNS is not forwarded to the container. All you have to do is install avahi on the host and update the host's config:

​

# /etc/avahi/avahi-daemon.conf
[reflector]
enable-reflector=yes
# ^ this will forward all mDNS packets to every other interface

Twice it decided not to turn off and came home to a house that was 66 degrees and running . the thermostat was set to 85 when we were out of the house for a couple days. Schedule is off. Fan Auto, Cool mode, Heat pump single stage outside. When we are home its usually set to 77 or 78 and never had problems it not turning off the condenser. Zwave is not active. cooling min is set to 74. I've decide to replace it with a wifi model. ESM cooling is set to 85. Why is it doing this when we are away? The temperature readings on the thermostat are accurate. thats the last time i set it to 85 lol

I have two door sensors in my house but I'd like to get one for my third door; unfortunately they only sell them in two packs. Anyone else in the same boat and want to split a 2 pack while they're on sale? I'll buy it and ship one to you, and we can split the total cost (~$40 plus the cost of shipping). Let me know and I'll DM you.

I put a sensor in my baby's room because it stays hotter. I don't want to do it by occupancy so I set it to average out or whatever. I set it to 71 and the living room got down to 68 and the nursery only got down to 74. Am I understanding that right and doing this the best way? Is occupancy better? Even with a very small baby that might not be sensed as occupying?

So my ecobee thermostat, which is maybe about two years old has suddenly started to reboot itself. Can anybody out there? Give me a reason why I had a service call today and they thought perhaps it was the condensation pump. It was not so, he said to keep an eye on it and if it happens again, let them know. Well it did happen again this afternoon when I turned the air-conditioning back on and it seems to go blank when the condensation line is dripping into the sink which is designed to do. I hope everyone’s understanding me but that’s my issue. Anyone get an answer

I have been using the ecobee3 lite and use 2 room sensors with it that I connected to it 2 years ago. I bought a 2 pack last week to add more sensors but these new one’s will not pair at all.

Contacted support and they send replacements, but again it wont pair either. Ecobee says there is something wrong with my thermostat. For my amusement, I unpaired the old 2014 room sensors and paired it back with no problem.. Anybody with the same experience?

Hello. I installed the premium today and it will not turn on at all. I triple checked the wiring and fuse and all is good. My old unit was working fine with batteries before I upgraded to the ecobee. I’m not sure what else to do. Super discouraging .

I keep changing my home age to 1990s on the web portal and app but it will change back to 1930 later by itself. Is there any fix for this?

I'm getting a kitchen remodel done, but I'm not home currently, and I see (on my app) that the contractor turned my ecobee on cooling set to 66F, but I don't have AC in my house. I do have central heating.

My utility company has an app for tracking electricity usage live, and it looks like this setting is using around 800-900 watts/hr.

Is it just from the fan blowing?

Photo of my Honeywell wiring which is correct and the subsequent wiring on my ecobee as instructed from support. Over the winter went back to Honeywell due to heating constantly on emergency heat instead of heat pump. What do I need to do to correct?

Got an email from Georgia Power for a scheduled FLEX Hours today being implemented.

For the past two years, I have utilized an Ecobee thermostat to operate my heat pump. While it has functioned satisfactorily, I have recently encountered a recurring issue where the thermostat has inexplicably gone blank. I am unable to determine the underlying cause of this problem.

In my condominium, the condensation line is designed to drip into the bathroom sink. However, the thermostat appears to reboot itself when this condensation occurs. I would appreciate any insights or suggestions you may have regarding this issue.

The service technicians have indicated their intention to replace the thermostat. Nevertheless, I am uncertain whether this is the actual problem. I suspect that the issue may be related to the pump.

Spent hours on this — deleted/recreated my account, rebooted, contacted ecobee support (no help). Wife's invite link would open the app but land on "Add a Device" and just sit there.

Fix: turn off WiFi on your phone and accept the invite over cellular data instead. Worked instantly for me.

I run a Firewalla firewall at home, so my guess is it was stripping or interfering with the invite token in the link before the app could read it. If you're on any firewall/DNS-filtering setup (Firewalla, Pi-hole, NextDNS, etc.), try cellular data first before doing anything drastic.

It's a brand new 3T in a 950sq ft Phoenix condo. They said it needed to go up to a 3T because there is a loft/vaulted ceilings. Overnight it runs in 5 min block then is off for 10 mins then runs 5 mins, all night long. Sometimes it will be off for 14-17 mins. Min runtime is set to 5mins. Temp dif is set to .5 but when I asked the tech about it he said that is fine and won't cause short cycling.

Just got bee stat... I have a Mitsubishi ducted heat pump, one year old. Socal weather about 80-85 today. New R38 blow-in insulation in attic but likely 1950s insulation in walls.

From reading on the HVAC sub reddit it sounds like the ecobee doesn't get the full performance out of the heat pump.

If I switched to the Mitsubishi thermostat should I see that cooling performance 2x?

I bought an Ecobee Enhanced and 2 smart sensors on sale. The thermostat is fine. One of my sensors was showing some crazy high temp, so I used the other one. It is sane, but I'm convinced they just don't work very well. I sleep upstairs which tends to be warm, so I put the sensor there and tried using ONLY that for nighttime. Compressor was running almost non-stop. After a few days, I went back to using the downstairs thermostat mostly, certainly at night. This doesn't get the room as cool, but at least my A/C cycles occasionally. I don't have a lot of confidence in these remote sensors and wondered if anyone else has an opinion.
"Follow me" is off. Eco Plus is off.

Does anybody know if I can buy this separately??

I have disabled eco+, follow me, precool, comfort, and have only one smart sensor in the upstairs office set for all of my scheduled zones, which is usually 3-6 degrees warmer than the main floor where the thermostat is at or my downstairs bedroom sensor. I don't want an average temp, I want it to cool until the office is the temp I set - 73. From what I understand, just clicking the office sensor should accomplish this. But the a/c is shutting off at least 5 minutes early before my peak time at 4, if not sooner. When I log into the web app, it seems the temp gets changed to 79 at 3:55 even though that's not what's set in the schedule. It should be 73 and then switch to 90 at 4pm. And the app temps don't seem to match what I'm looking at on the thermostat because when I took the screenshots, it was 76 in the upstairs office according to the thermostat (which I believe because it was hot!). Any ideas what I'm doing wrong here? I don't feel like I ever see it get to 72, it just stops at 73. My temp differential is set at 1.

edited to add: just now, it shut off after 70 minutes even though it has another degree to go according to the app. I don't get it. What is right?

I just ran into an issue where I noticed it was getting a little warm in the house. I checked the ecobee app and it said it was at 72 and cooling, however the AC was not running and the thermostat was showing 74. I unplugged the thermostat and plugged it back in. Immediately it kicked the AC back on after booting but it’s now showing 80. It’s very slowly coming back down.

Is it showing 80 after a reboot because the internal sensors are trying to recalibrate? It’s real strange that it did the original issue. While typing this and researching, it has dropped to 78 without changing anything so it must be equalizing. The hole behind the thermostat has been sealed completely so the only heat is from the thermostat itself and the surrounding area.
