Can you please advise on the question above? I have the nest thermostats (non learning, not e) and using the home app. I'm trying to change the temperatures for the preset "eco". I am away for several months of the year and want to hold the temp in my house at 60 degrees in the cooler months --not 56 degrees (which is the current preset value). My understanding is This is the only way to hold a temp for longer than 24 hours at a time. Otherwise, I'm having to check every 24 hours and put the temp manually back to 60, which is ridiculous and impractical. Can I change the preset value of eco ? Otherwise How can I set the thermostats to stay at 60 for extended periods of time?
