Why won’t my gateway connect to Wi-Fi?
Ensure the gateway is within 330ft (100m) of the router in open areas using 2.4GHz Wi-Fi (5GHz unsupported). Range reduces with obstacles.
Will I be notified if my device disconnects from the network?
The sub-device contains a built-in battery, such that even in the event of a network disconnection, it can actively sound an alarm if the temperature exceeds the threshold, thereby providing an alert.
Why does my device keep disconnecting?
Common causes: 1) Closing app breaks Bluetooth connections 2) Exceeding range limits (230ft/70m max open area, 100ft/30m with obstacles). Keep devices within range and avoid obstructions.
Why is there no alarm sound from my device?
Alarms are muted by default. Adjust volume in peripheral device settings.
How to turn off the beeper alarm?
To ensure optimal temperature monitoring and timely alerts, when the buzzer alarm activates, you must approach the device and briefly press the side button to silence it.
