What is the button on the Powersensor device used for?

The button on the Powersensor is used for several functions. The necessary action depends on the current state of your sensor. This article contains button functions for when:

Your sensor is off

Your sensor is on but not installed

Your sensor is on in the normal operating mode

Sensor is OFF  

A momentary press of the button will turn the device on:

Once it is on, the device is ready to be attached to a WiFi network and installed.  

NOTE: if you hold the button down whilst the device is powering up, it will enter a factory test mode.  The factory test mode does not perform any user functions! This is what the LEDs display in factory test mode:

If you inadvertently place the device into factory test mode, simply press the power button momentarily, and it will exit this mode. You can then start over again.
