After power outage no connection Photon 48-V2 Pro

BCSreef · Jul 3, 2024

This is a recurring issue with the old and the new app. I have two 48-V2s and both have had the issue. Often after a power outage or a power cycle, one of the fixtures loses connectivity. I try to connect according to app instructions with no luck. In the past, I was able to connect only after repeating the connection attempts many times. It often took over an hour to get the fixture to connect to the app. Today, same issue. After an hour and many connection attempts, no connection. After repeated attempts, still no connection.

A summary of what I'm doing:
I reset the fixture either with the button or by unplugging the power supply.
The blue light blinks slowly.
I follow the app instructions, select the Photon Wi-Fi and the light goes to a rapid blinking blue.
I select my Wi-Fi router and the light goes to a solid blue, then a slow blinking blue.
No solid green light.

Does anyone have a solution to this issue?

Hey there,

Sometimes after a power outage it takes time for the internet to come back. If you power cycle the light by unplugging it from the wall for 30 seconds, then plugging it back in- it will initialize a reconnect automatically, with no need to reset the light.

When you reset the light- you need to start from the top and reconnect in the app, as it clears the schedule and wifi credentials from the lights memory.

I recommend waiting a bit for the wifi to be stable after the power outage, and if they don't auto connect after an hour or so, power cycle the light as described above.

This also applies if the light is blinking blue when it should be connected.
