Good morning! None of my pool equipment is set to run between 10 PM and 9 AM. The last two nights, the pool and spa have been cycling on and off between midnight and 7 AM. Here are screenshots of the history on my Pentair app from yesterday morning and this morning:

I realized yesterday that my Easytouch/Screenlogic system was not password protected, so I fixed that to make sure this was not someone accessing the system remotely. However, the problem reoccurred last night. I checked the programmed schedules and there is nothing that would explain this. I am in Southern California and the pool got covered in ash this week. I read online that clogs in the system/filter could lead to pump cycling, but nothing about the system cycling itself while it is set to be off. Does anyone know if that is something that could happen - the system turning itself on in response to filter clogs? For now, I've turned everything off at the breaker, and I'm going to open up the filter. Assuming it is going to be very dirty, I'll clean the cartridges and see if that fixes the issue. If anyone else has any ideas in the meantime about what is causing this, I would love to hear them, especially if this is a known issue or something more serious that I might need to get professional help with. Thanks!
