Firstly a comment to Nest Support. Please stop your condescending replies “we’d love to help”. All it is is words. My Nest thermostat is 3 years old and and constantly changes to “away” and “eco” when we’re home and regularly walk in front of it. Have called support a few times and spoken to people who actually don’t know the product or understand what the problem is or able to help me rectify it. So regrettably the bin is the next move.
