Troubleshooting

Press and hold the button on the back of the Shelly 1PM Plus for 10 seconds to factory reset the device.

Please make sure that you are running the latest firmware and try turning on the Shelly Cloud connection through the web interface.

Make sure you are not using the L and N device terminals as bridges. Using them as bridges doubles the current through them which leads to overheating. Using the terminals as bridges in only available with low currents, so that the total current does not exceed 16A.

 

Make sure the ambient temperature does not exceed 40 °C / 105 °F. If placed in confined space Shelly Plus 1PM may increase the ambient temperature above the allowed limits. Ensure ventilation of the Device.
