Hi, might you have 2 or more Jebao SLW wave pumps and have them set to master and slave? The wireless connection between the pump controllers causes interference between the reefbreeder light and remote. Maybe other jebao pumps the the wireless master/slave option may also cause this, but I don't know as I only have 2 SLW-30's in my system.
I was having weird happenings with my V2+ shortly after installing the jebao pumps and reached out to reefbreeders and they said it was possibly the jebao's and sure enough it was.
Turn off the master/slave function on the wave pumps, then use the remote and go to the time setting and scroll through the entire day several times. This should get the correct programming to the light. Once that is done you can turn on the master/slave option again and experience normal operation for the light and pumps.
Now every time I make a programming change I turn off the pump link and do the procedure above and so far (about 6 months now) I've had 0 issues with the photon.
Hope that helps.
