If your home WiFi network is visible in the Lyric app and you have provided the correct WiFi network information, but your thermostat has not connected to your in-home WiFi, you may need to troubleshoot your WiFi network. First, confirm that your router is using a supported security standard. Lyric works with the following security standards:
- OPEN
- WEP_PSK
- WPA_TKIP_PSK
- WPA2_AES_PSK
- WPA2_MIXED_PSK
Second, confirm that your WiFi network is compatible. All Honeywell WiFi thermostats, including the Lyric thermostat, are compatible with the 2.4 GHz B, G and Mixed WiFi networks. Third, some routers are incompatible with the Lyric thermostat's low-power features. To see a list of compatible routers, visit here. Note that this is not an exhaustive list of compatible routers.
