Resetting the Homey Energy Dongle to factory defaults will erase all stored data, including Wi-Fi credentials and smart meter connection settings.
To perform the reset, use a long pin to press and hold the pinhole located next to the Homey Energy Dongle’s USB-C port for 30 seconds.
When held down, the LED breathes red a few times before blinking red. When it blinks red, it is safe to remove the pin. At this point, all data is being deleted.
Shortly after, the LED blinks white, indicating that the Homey Energy Dongle is restarting. Once restarted, the LED breathes blue, signaling that it is ready to be set up again.
