Why would you need to know how to find Honeywell thermostat IP address? You would check for a valid address on the thermostat to make sure that the t-stat is linked to your WiFi network rightly. Knowing that your t-stat is working with a valid IP is a valuable aid. It helps in troubleshooting internet problems between your smart t-stat and the Honeywell Total Comfort Connect website. With no IP address on your t-stat, you won’t be able to control it outside your home via your phone, tablet, or any other device for that matter.
