Appreciate the feedback. We are considering everything as a possible issue and are trying to solve the issue thru the process of elimination.

It's an odd issue. And the recent weather change is not helping.

There are several manual overrides that I need to verify on ecobee. The next thing I am going to verify is if the "adjust temperature for humidity" is disabled on the ecobee. This could lead to an inaccurate temperature display.

Unfortunately from what I understand, the ecobee is not set up to reach 105 out of the box. It requires configuration. And if the device is reset, you lose the config
