My Honeywell Lyric is not Connecting to WiFi
What band is your router broadcasting it’s signal on?
The Lyrics operate on the 2.4GHz band. So if your router doesn’t broadcast a 2.4GHz signal you are going to need to upgrade your router – probably to a dual band router so that you can take advantage of both bands. A dual band router broadcasts two signals – one on the 2.4GHz band, the other on the 5GHz band – each band is useful for different scenarios.
The easiest way to check the signal broadcast by your router is to check the connection properties of one of your existing devices (eg your phone or tablet) to the router. Navigate to your device’s WiFi connection properties, and amongst the properties you should see something like
Protocol: WiFi 2.4
Network band: 2.4 GHz
If you’re seeing 5 GHz, not 2.4 GHz, then try making a new connection to your router. If it’s broadcasting dual bands you will see one for 2.4, and one for 5. So in this case your router is fine, and the Lyric will be able to connect to the 2.4 GHz signal. If you only see the 5GHz signal then to get the most out of your Lyric you will need to upgrade to a dual band router.
Once you have a router broadcasting a 2.4GHz signal, your Lyric will be able to connect to the network. If it hasn’t connected automatically, for a Lyric T5 or T6, press and hold the temperature display in the centre of the screen for 5 seconds. This will reset the WiFi connection.
Ok, so my Lyric is on the network. How do I interact with it?
First, make sure the device you are using is connected to the 2.4GHz signal from your router – that is where you’re going to connct to the Lyric. Note, your device needs to be an Android or iOS smart phone or tablet.
Second, download the Lyric app from Google Play or the Apple App Store. Once installed, open the app, and you should see your Lyric listed as a “found” thermostat. If you don’t see it, tap “Install a Device” and follow the instructions on screen.
My device was connecting to the Lyric – but now it’s not!
There are a number of possible reasons for this – so it’s best to go through the process step by step.
First step, remove the Lyric from it’s sub-base on the wall, and wait for 15 seconds. Then replace it on the sub-base. This will force a reset to the WiFi connection to your router. Now try connecting from your device again.
If that hasn’t worked, second, uninstall the Lyric app from your device, and then reinstall from Google Play or the Apple App Store. Log in, and retry the connection to your Lyric (you should see the Lyric’s ID – something like “Lyric XXXXX” – in the Thermostat Found section.
Still no luck? Try rebooting your router. Switch it off at the mains socket, and wait for 10 seconds. Then switch it back on. The Lyric should automatically reconnect when the network is back up. Switch your device to Aeroplane Mode – to ensure you can only connect to the router – and try connecting again.

Can I still use the Lyric without WiFi?
Yes you can. You lose some of the “smart” features – like geofencing and shortcuts, and the convenience of being able to manage the Lyric from your device (at home, or remotely when away from home), and some features that are only available in the app (like Vacation Settings) – but the Lyric is still an effective programmable thermostat – even without connecting to WiFi.
It’s just better when connected to WiFi and using the app!
