Do I need to use the wired Nest Protect for a previously wired system or can I switch to the battery version? Are there any pros or cons for the battery vs wired Nest Protect systems?

Hey Ashlea, 

Thanks for reaching out to us and welcome to our community! We're happy to hear that you're considering a Nest Thermostat for your home. 

This handy guide should help you compare and contrast battery/wired Protects. For a battery model Protect, it can offer convenience since it doesn't involve connecting wires. For a wired Protect, you would receive consistent power (120V - 240V), and its batteries are used as backup in the case of a power outage. 

I hope this helps! Let me know if you have any other questions for us.
