Nee house has Nest - no instructions left

[Kimjw55]

I just bought a house and moved in last week. It has a Nest thermostat and I have no idea how it works. It complained about no internet connection. I watched a video about how to make it entirely manual.  Now only the thermostat in the bedroom works. 

my questions: 

1 can I set the thermostats in the other rooms (at this point they just say Not Connected to WiFi for N days)

2 If I connect it to my internet is that all I have to do to control each room separately 

3 not interested in an app I have to pay for that knows when I’m home and when I’m not. Jeeez.  Do I need that to use all the thermostats?? 

4 if there’s a detailed manual can someone send me a link? 

thanks.

The first thing to do is to factory reset the thermostat. Once reset:

If it's a Nest Learning Thermostat or Nest Thermostat E:

1. If you haven’t already, download the Nest app on a phone or tablet.
2. On the Nest app home screen, tap the Settings cog.
3. Tap Add product. The app will switch to a camera view to scan the thermostat’s QR code.
4. On the thermostat, press it to open the quick view menu and tap the Settings cog.
5. Turn the ring to select Nest app and press to open it.
6. Select QR code. Your thermostat will show you a unique QR code to scan with the app. If it doesn't, tap Continue without scanning in the app and select Get entry key on your thermostat instead.
7. Follow the remaining steps in the Nest app.
   
   

If it's a Nest Thermostat (2020 model), follow these steps:
