Sensor plot not matching actual indoor temp

I just noticed that at around 5pm (East Coast US) on 3/10, my indoor temperature plot is no longer matching any of my sensors. I actually can’t seem to figure out what it is aligned to as it is greater than all sensors on my thermostat.

Could you post a screenshot of your Thermostat Detail and Sensor Detail charts for the same time period? That will help. You might also open up the ecobee Home IQ website and see if that shows the same thing as beestat.

Normally I’d say there’s just some sensor averaging going on, but if your indoor temperature is higher than any of your sensors then that doesn’t quite fit.

NOTE: Home IQ generally shows the same thing as the Indoor temperature, but I can’t find any details on sensor data to compare to.

My upstairs has its own heat/cool forced air unit. I mainly have the ecobee3 lite regulated based on the “Kids Room” temperature (blue). The thermostat itself is “Master Bedroom” in Red and suffers from self heating and draft changes when the 1st floor unit turns on (not shown). The Yellow signal is a sensor in the same room as the thermostat.

Something odd happens at 5pm and then goes back to normal at a profle change at 2pm the following day.

Here is a view from the previous night where you can see the indoor temperature and the kids room match during my sleep comfort profile. At around 630am the wake up profile becomes the average of the master bedroom suite + kids room to help me get out of bed. This is all expected (except the missing data piece but that doesn’t bother me at all)

Sorry for the delay on this; finally getting back to some of these issues. The first thing I think we need to do here is see what data ecobee has. Could you upload a CSV export of your ecobee data for the affected time period? This will show us all of the sensor temperatures as reported by ecobee.

I need to validate that it’s not a sync issue first. Once we establish that, then we can try and figure out why.
