If your Phyn Smart Water Sensor was previously paired to a different Wi-Fi network and you need to connect it to a new network, you must perform a factory reset.
Before starting, insert two new AA batteries into the sensor.
Factory reset instructions
Locate the button on the side of the sensor to the right of the Phyn logo.
Press and hold the button.
While holding the button, the Phyn logo will flash in the following sequence to indicate reset progress:
Yellow
Off
Yellow
Off
Yellow
Off
Release the button after the final flash sequence.
After approximately 5–10 seconds, the Phyn logo will display:
Two blue flashes
One green flash
This flash pattern confirms the factory reset is complete and the sensor is ready to be paired again.
If you do not see two blue flashes followed by a green flash, repeat the steps above.
Important note
A factory reset does not automatically place the Phyn Smart Water Sensor into pairing mode
During setup in the Phyn app, you will be prompted to put the sensor into pairing mode
To enter pairing mode, press the side button once
The Phyn logo will flash blue and white to indicate the sensor is in pairing mode
