Thermostat has been working well until today. Now the heat won't come on. Did a reset, that did not help.
When I adjust the temperature a green leaf shows up and says in 1.5 hours, then says until 21:00. It's -4C outside, by 21:00H my pipes will be frozen. Support web site says they are open but all channels of communication are greyed out and unavailable.
Can anyone help?

I don't have a Nest app on my phone and don't want one. Nest came thermostat came with the house. Nest web won't work unless I allow third-party tracking cookies, I'd rather rip the Nest off the wall.
For the moment to prevent your pipes from freezing, you should be able to jump the Rh and the W wire which should turn on your heat. Keep in mind that it will not turn off until you take the jumper off !
I have the exact problem and support has been no help. Nothing has changed in my environment. They indicate it must be a wiring problem on my side. I explained that if I can jumper the wires and the system comes on that the system is working as designed.
I Have the same problem and I do hear a click when I adjust it. It says it will reach my desired temperature in an hour and 10 minutes but it said that an hour and a half ago. We don’t have any heat
I am having the same problem. It happened 12 times in November. I lost track how many times it happened in December but most of the time it happened when it was time to go to sleep and I needed it most. Now in January, 3 nights in a row I had no heat and kept playing with the app for over 3 hours until it kicked in. Today I have had no heat at all for the last 12 hours and still don't.
After about a year, we now have the same issues as disappointed. The thermometer does not follow schedule. Restart and Factory Reset didn't resolve issue and wiring is correct. Yes, I do hear the click. When lowering the temp manually and then increasing well above scheduled setting, the HVAC kicks in with cold air for about 3 min prior to turning off. During the two last nights, the heater kicked in well above Sleep setting as well.
I have this same problem: Nest says it's heating, but the boiler isn't on. The wiring is correct, and jumping the wires turns on the boiler. The thermostat is fully charged. The boiler is serviced professionally. This was never a problem until the past month. What changed? Is it a software problem? This is very frustrating!
Cristian - do you know if there is a way to roll back the firmware to a previous version ?
I find it concerning that there are so many people complaining of a similar issue that all began Sept/Oct time frame on systems that had previously been connected and working. I get it if anything changed, or for a new installation that you can't get to work. However all of the complaints that I have heard are for existing systems.
I just ordered another brand thermostat and will be interested to see if it works with no changes to the wiring.
Same here! Sept to Oct time frame
Same happened to me SEPT OCT time frame
