Hello.

1) While TRYING to work with my PB and Hayward on some odd and transient COMM and low voltage alerts, I noticed that my Omnihub only shows an MSP and not an MPP in the SysInfo display. Is that normal? I don't see a way to scroll for more info- I was thinking maybe it was on the next page of info. Most of the TFP Wiki and Hayward articles indicate that I should see both.

2) The COMM issues started a little over a week ago (the pool has been up/running since ~August 2021). They cleared on their own. A few popped up during the day and I ran outside to look at the hub and AQR - there didn't appear to be any issues. Hayward told me to clear the DDT - but I'm on 4.3.2, so there is no DDT manipulation. They responded with "With the newest revision software shell command has been removed, and the system no longer has these functions" - and that was the end of the communication. I shut the system down and then switched the breaker off for 5 mins. Turned it back on - 2 days with no issue. This morning I have an alert for Low Voltage for Chlorinator1, and it cleared an hour or so later. My guess is that it cleared much earlier, but the alerting/emailing isn't real time. Am I looking at the AQR going bad?

Maybe @PoolBrews will have ideas about your MPP question.

The Low Voltage for Chlorinator1 could be a sticking K1 or K2 relay as they energize the SWG. Could be a problem developing on the board.
