Had a Nest for apx year or less. WIFI packed up only to find out this is ongoing problem with Google Nest since google bought it and transition to their infrastructure. Absolute joke. This is not how it was as I used it in my home and installed nest to clients since it came out. It was brilliant and a pinnacle of thermostats especially appearance. Somehow Google managed to screw it all up. Will be going to Hive unfortunately as it has been few weeks now and none bothered to replace under warranty
