Solution 4: Make use of the Google Nest Power Connector
The Google Nest Power Connector is a convenient solution designed specifically for Nest customers who don’t have a C wire. It provides a reliable and safe connection that will keep your thermostat powered on and working optimally. But if you’re not willing to spend money on this solution, or if the Power Connector isn’t readily available, there are alternative ways to ensure your thermostat gets steady power.
