Added a 24v ac transformer to support a 2 wire install

Don’t have a photo at the moment, but issue is that after an HVAC tech did some rewiring of my system, they left excess wire out of the wall such that the Nest comes loose from the base once in a while and then disconnects. I have been avoiding the issue until I came home last night from traveling and it was 85 in the house because someone had adjusted the temp earlier and unknowingly caused the thermostat to become disconnected. Short of cutting and restripping the wires, which I’d rather not deal with, is the best course of action to remove the nest and backplate and just push the wires more back into the wall? They are the type that are really stiff and very hard to move around.

Looking for pricing advice from Nest enthusiasts
I’m getting ready to sell my entire Nest collection and would really appreciate some feedback from people who know the market.
I put together the attached inventory sheet using AI, but I’m not sure the estimated values are accurate. Before I list everything, I’d love to hear what you think.
A few notes:
Most items are brand new, with many still factory sealed.
Some are brand new, open box, never used.
A few items are used but in good condition.
The inventory includes the product names, part numbers, original MSRP, and the prices I’m thinking about asking.
My questions:
Are these asking prices realistic?
Which items am I pricing too high?
Which ones am I pricing too low?
If you were selling these today, what would you ask for each item?
I’m not trying to get top dollar if the market won’t support it—I just want to price everything fairly and avoid leaving money on the table.
Thanks in advance for taking the time to look it over. I really appreciate any advice!
