Troubleshooting

Symptom	Possible cause	Solution
The unit does not function at all or the lighting does not turn on.	No mains power supplied Incorrect wiring The ambient light level is too high Malfunctioned load	Check or switch on the power. Check the wiring, refer to wiring diagrams. Reset the LUX value to be higher than the ambient light level. Replace with new load.
Lighting does not turn off	TIME set too long False trigger Incorrect wiring	Adjust TIME value shorter. Ensure sensor is away from heat source such as air-conditioner, electric fan, heater or highly reflective surface. Ensure there are no swaying objects within the detection range. Check that the load is not wired directly to the power supply.
Lighting turns on and off Quickly	TIME set too short False trigger Wrong modes (Short pulse mode or Test mode)	Ensure sensor is away from heat source such as air-conditioner, electric fan, heater or highly reflective surface. Ensure there are no swaying objects within the detection range. Ensure sensor is not set to Short Pulse mode or Test mode.
Unexpected or False Trigger	Some object cause unexpected trigger. Other wireless signals affect the device.	Ensure sensor is away from heat source such as air-conditioner, electric fan, heater or highly reflective surface. Ensure there are no swaying objects within the detection range. Ensure the device is away from wireless signal sources like Hub, Wi-Fi^® device, base-station.
The motion is detected but fails to trigger the load to turn ON.	The micro module is not paired to the motion sensor. The micro module is far away from the device or there is a thick wall in between the device and the micro module.	Make sure the Micro module and the motion sensor are paired correctly. Refer to Pairing Micro Module with Motion Sensor. Make sure that there is no more than a 20 meter distance between the micro module and motion sensor after passing through a single 25 cm concrete wall.
In the app No Signal appears for the motion sensor.	Device is powered off. Wiser hub is too far from the motion sensor.	Make sure that the motion sensor is powered on. Move the Wiser hub closer to the motion sensor. Restart the motion sensor.
displayed in the Wiser Home app. [ERRORCODE]: Your <Device Name> is currently overheated. The <load type> is currently turned off. This will become active when the motion sensor moderates it’s temperature. – Displayed in the Wiser Home app.	The motion sensor is overheated.	The motion sensor will restart after some time when it cools.
