This article can help you if you have a T5 or a T6 thermostat. For other Wi-Fi thermostat models, please check our full list of Honeywell Wi-Fi thermostats.
There are several reasons why your thermostat cannot "see" the Wi-Fi home network. First, verify the following:
Please note that if you live in an area with many Wi-Fi networks broadcasting in the same space, it's possible that your thermostat did not find your network on the first scan. You will need to refresh the network list by pressing the "Refresh" button on your Honeywell Home app screen and try connecting again.
Also, if you have chosen to use a non-broadcasting SSID (network name) on your router, your network name will not appear on the Honeywell Home Wi-Fi list. You will need to manually add your router using the "+" button at the bottom of your Lyric app screen.
If the steps above don't provide a solution, you can try and reset your thermostat. You can reset your credentials just for your Wi-Fi connection, HomeKit, or Program Schedule, or you can bring your thermostat back to its factory settings.
Please follow the instructions below to reset your thermostat:
