Glow requires a constant WiFi connection in order to function. Glow uses WiFi to send air quality information to our cloud server, and relayed data back to your phone via the Awair app. When Glow is disconnected from WiFi, it will appear grey in the Awair app and the light on the device will begin blinking. If Glow is disconnected from WiFi for more than 30 minutes, it will trigger the Automatic Shutoff feature, which will turn off the device. This feature can be disabled in the device settings page of the app. Triggers, integrations, historical data, and other preferences will be saved if Glow is disconnected from the internet.
Glow communicates directly with your smartphone using Bluetooth Low Energy (BLE). Glow requires Bluetooth for the initial pairing process during setup, but afterwards can be controlled entirely by WiFi.
Required WiFi Specifications
Glow is only compatible with 2.4GHz B/G/N WiFi networks. Glow can operate on dual band routers (2.4GHz and 5GHz), but we recommend giving each band a separate SSID before connecting to the 2.4GHz network. We also recommend turning off the load balancing feature for dual routers, as this can occasionally move Glow to the 5GHz network. Your firewall must also allow access to TCP ports 8883, 123, and 443.
Unfortunately, Glow is not supported on mesh networks, Zigbee, or Z-Wave.
