Is my wiring compatible with Nest?

[hbc27]

 We currently have this thermostat with a NO and a COM wire, and a blue wire that isn’t connected to anything. Is this compatible with any Nest thermostat?

Best bet is to use this tool (https://store.google.com/us/widget/compatibility/thermostat) , if it asks you to send a picture you would send it to the Google support team not this forum.  you can contact support here(https://support.google.com/googlenest/gethelp)
