SMS Mode (Default)
After the Controller is powered on, the SIG indicator blinks twice. This indicates the current mode is SMS mode.
To switch to SMS mode from Network mode: Press and hold the SET button before power on, wait for the SIG light to blink twice, then release your finger.
Network Mode
After the Controller is powered on, the SIG indicator blinks four times. This indicates the current mode is Network mode.
To switch to Network mode from SMS mode: Press and hold the SET button before power on, wait for the SIG light to flash four times, then release your finger. Note: Before entering network mode, APN must be set up via SMS.
Operating Instructions
Mobile APP Control
The Fockety SM8 WLTE can be controlled and monitored via a dedicated mobile application. Download the APP from your device's app store (search for "SM8 WLTE" or refer to the QR code in the included quick start guide if available).
Function 1: Temperature Control
The APP allows you to set temperature thresholds. When the detected temperature reaches the preset value, the device can trigger the relay to operate and send an alarm message.
