Working with 2nd gen Nest

[altsysrq]

Recently, I wrote up a small instruction on how to get Nest to work with multiple sensors. The goal of this writeup was to use alternative sensors outside of the Nest thermostat due to a problem I had with its location near a minor heat source. This is done by disabling some of the features that are built into the Nest which makes it essentially an on/off heater control and control it with HA’s generic thermostat module. . . There has to be a better way of doing this.

The post can be found here:

Multiple sensors with generic (virtual) thermostat to control Nest

I have an issue where my second generation Nest thermostat sits right behind my TV. This creates a small but noticeable difference in temperature when the TV is on. Additionally, at night it tends to get warmer upstairs the colder it is outside. The heat may be on for longer which accumulates upstairs. Turning on the house fan regularly through Nest to circulate the air does not seem to help. It seems that secondary sensors are only compatible with third generation Nests on up. I fixed this by…

Is there a way to root, or hack the Nest that might allow some of these functions?

• Offsetting/change/calibrate the default sensor in Nest by a certain number of degrees to match an external sensor
• Have Nest refer to a 2nd sensor

Otherwise, as I mentioned in the original post I could:

• Replace Nest with Ecobee or 3rd gen Nest with multiple native sensors
• Move my Nest to an ideal location

Are there any other suggestions?

Followup:
I moved my Nest out from behind the TV. I have plans to test and work with the following changes:

• When night mode is on and bedroom sensor is off by X degrees from start target temperature, change target by X (tricky), revert to start target temperature when night mode ends
• When home is occupied and night mode is off and 3 sensor’s variance is X turn house fan on for 15 minutes
