What model of Nest Thermostats do you have at each location. I ask this because the Nest Thermostat can only interface with Google Home app. additionally the Nest Learning Thermostat can interface with both the Nest App and/or Google Home App. As to turning off the ECO mode using the Google Home app, it is pretty simple and straight forward.
1. Open the Google Home app,
2. scroll to the thermostat, tap to open the thermostat,
3. looking at the screen below the indoor temperature, you see an image of a leaf. Tap that leaf, and select the mode you want. Your choices will be Heat, Cool, Heat*Cool, ECO, and OFF.
As to the second home, if the Nest thermostat was added to the Nest App, it should still be there unless someone opened the Nest App and chose to “Remove Thermostat”. The Nest App does not arbitrarily delete a registered thermostat even if you add it to the Google Home app at the same time.
If a thermostat is being shown as being “off-line”, the app is telling you that the remote thermostat cannot be seen over the Internet. This can mean that either the thermostat has lost its connection to the WiFi network at its location or the Wi-Fi connection has changed i.e. a different service or a different router SSID. As long as the Nest Thermostat has a connection to the WiFi, and the WiFi router has a connection to the Internet, it should appear online. The only other possible failures are low battery charge, or a defective WiFi chip In thermostat. Most likely the WiFi chipped is turned off to save energy.
