When my t5's turn on the atu pump goes crazy. I belive uts caused through induction voltage as the t5 wires run close to the float switch wires. Any thoughts?

Have you tried moving the float wires away from the t5 wires?

I will have to do some rewiring.

But the issue goes away when the t5's are unplugged

I think I may be having the same issue but I'm using LEDs on PWM. I notice that my log shows that the ATO stops acting up once the lights dim down to 1% for the night. See my ATO relay log below, note that the actual water level was between the two floats this entire time.

The Portal only register events every 5 minutes.
If the event is quick, it won't register.
What I think you are seeing is just more evaporation during the day.

I disagree. This happens anytime the high limit switch isn't active. I have about 2.5 days of evaporation between the switched. I think I'm getting this noise issue much more frequently than every 5 minutes but it just catches a few in the log. I'll try cleaning up the wiring to see what happens.

Update: I'm in the process of switching my four led bars over to pwm control. The ATO issue is gone now that I disconnected one if my Chinese led drivers that was nearby the ato wiring.
