power up the sensor and the WiFi Gateway/GW1100 will
pick sensor data automatically.
If a WH45 sensor has been hooked on the WiFi
Gateway/GW1100 before, and you have a new sensor to
replace the old one, just power off the old sensor and
power on the new sensor, open the APP: WS View Plus/
Ecowitt App, tap the device and go to sensor ID page,
locate the WH45 sensor, select “Register”, then the
gateway will erase the previous registered sensor and
have the new sensor paired.
