Which nest do you have. I had to replace one of my four bought in 2012 as it seemed totally dead. I don't want My older nests messed with by any electronics or the darn app in my phone. I prefer the old management from my computer. My new one got installed a G4cVZ $129 at home depot and was time consuming to get into my i phone 11 then the blue tooth disconected. Nest then told me maybe poor electrical connectivity so recommended I get a power connector to place at the furnace. I have trouble believing power is a problem as never ever saw it on off or on low power mode ever. I hate the app. I always use the scheduling to control our temperatures as we cannot be observed by 4 different thermostat areas or 4 thermostats to suit our schedules. On the new one I couldn't so do that. I suggest you try using scheduling by hour and day to control yours maybe that may work or make them replace it. google their customer service phone number for a live rep who might be able to help.
