thanks for looking into this for me Roberto. I have been testing multiple triggers everyday for the past week and did get the two messages you mentioned. problem is those are the only 2 I received.

That ATO High Port =0 triggered every hour for 4 days before I got the email, I have no idea why it took so long to send the email? I have since deleted it.

The ph trigger was raised to < 8.2 in order to have it trigger each day.
