How do I restore H2know’s firmware to factory settings?

A factory reset, also known as hard reset or master reset, is a software restore of the firmware on your H2know sensor. A factory reset can fix chronic performance issues with the sensor (i.e. freezing), but it does not remove the sensor’s operating system or the Wi-Fi credentials stored in its memory. 

To perform a factory reset: 

1. Remove power from the sensor.
2. Press and hold the “Reset” button on the face of the sensor.
3. Connect power to the sensor while continuing to press and hold the “Reset” button.
4. Continue pressing the “Reset” button for 6 seconds, then release the button.
5. The sensor should come up with a FAST BLINKING GREEN LED (i.e. 200 msec GREEN on, 200 msec off, repeat). 
6. In approximately 3 minutes (or less), the sensor should reboot and display a SLOW BLINKING GREEN LED (i.e. 50 msec GREEN on, 3 seconds off, repeat). This indicates the software on the sensor has been restored and the sensor is actively transmitting data.

Note: If the sensor has a FAST BLINKING ORANGE LED instead of a FAST BLINKING GREEN LED as noted in step 5, this means that the sensor cannot connect to the Internet via Wi-Fi to download a new version of the sensor firmware. If this is the case, it could be caused by incorrect Wi-Fi credentials stored in the sensor’s memory, a weak Wi-Fi signal where the sensor is located, or Wi-Fi router issues. Please ensure strong Wi-Fi signal strength or reset the Wi-Fi credentials stored in the sensor’s memory. When new credentials are loaded into the sensor, it will automatically reboot into factory reset.
