I purchased and installed my Ecobee 3 without any issues to speak of, it is in the details that I am having some concerns. I have 3 remote sensors. Originally 1 in the master bedroom, 1 in the 2nd bedroom, and one in the basement. I have Smart/Home Away disabled, Follow Me Disabled. The basement is unheated, and the 2nd room are currently not in use, so those sensors I have turned off everywhere, they are just for monitoring (BTW, Ecobee really needs to add a feature for Remote sensor specific alarms... seems like a no brainer).
Home set to Thermostat sensor, Sleep set to use just Master Bedroom sensor. Scheduled to sleep from 9pm to 8am. Pretty straight forward.
Anyway I was getting some odd results, occasionally my Thermostat would show 65 on the screen, but my digitial thermometer next to it says 69. I thought maybe it was averaging even though it shouldn't be.. They werent all during transitions either.
One time the thermostat said it was 68, yet NONE of the sensors (not even the built in ecobee sensor) were reporting 68... If its not averaging, where did that temp come from?
To troubleshoot the temperature reading I moved my basement sensor up next to the Thermostat. I also unplugged the ecobee and plugged it back in (per Ecobee support) to recalibrate it.
Since then the Remote sensor has been spot on, with 1 degree at all times of the digital thermometer. The Ecobee thermostat sensor on the other hand sometimes reports the same temp, other times it is 3-4+ degrees off!! The sensors are in the same location. They are on an interior wall, they are no where near any vents. (vents are by exterior walls)
I am at a loss. I had a GREAT service rep pre-Christmas. He said he was going to follow up when the logs updated (they are like 3 hours behind I think) then it was Christmas. After Christmas I had a different rep "follow up... I got a complete boob after Christmas who wasn't even properly acknowledging the problem (or all the work the other rep and I had already done). He was infuriating me and after a few back and forths I kindly asked him to forward me on to someone who would actually help.
Here is my Ecobee data. I have highlighted in Yellow the Thermostat Sensor Vs the Remote Sensor. These are in the same location (the red highlight is before I moved the sensor, it was in the basement). You can see how sometimes the sensor is the same, othertimes it is 3-4 degrees off. Again my digitial Thermometer and the remote sensor are always within 1 degree of eachother, so it seems the Ecobee Thermostat sensor is the problem?
Any advice or thoughts are much appreciated. Overall I am liking the Ecobee, I would just like to really not have to have a remote sensor mounted WITH my thermostat which is quite redundant. It unfortunately is the only way I can get accurate readings right now. I have switched my HOME to use just the Livingroom Remote sensor and now the thermostat sensor is doing nothing until I can get this resolved :-/.
My biggest concern being the random times the Thermostat sensor is reporting ~65 while the Remote Sensor and Thermometer are reporting 68/69.
