Why is my Lyric T6 Pro Wi-Fi thermostat not finding the in-home Wi-Fi network?
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:
- Your router is powered and broadcasting. You can check this on your mobile device by accessing an Internet browser. If you are not sure if you are using your mobile data or your Wi-Fi connection, put the mobile device in Airplane Mode, then switch on the Wi-Fi signal. If you can browse the Internet in this mode, this means that you have an active Wi-Fi Connection.
- Check that your router is broadcasting the Wi-Fi signal in the 2.4GHz range. This step is required for the following reason: most routers broadcast the signal on a dual frequency, 2.4 GHz and 5 GHz and most of the more recent smartphones and tablets can “see” both these frequencies. However, Lyric thermostats only operate in the 2.4GHz range. Check your router manual to see how you can make sure it’s broadcasting on a 2.4 GHz range.
Also, if you have chosen to use a non-broadcasting SSID (network name) on your router, your network name will not appear on the Lyric 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.
