Well that’s the thing, the messages stopped 15 seconds after the timer was supposed to start (I also didn’t receive any messages saying it around the time it stop).
I was not around to actually check if it ran for the full 48 minutes, and I didn’t see the messages until the following evening so I couldn’t tell you if it actually ran or not. I can keep an eye out the next few times it runs if that would help.
Is there another way to check the run stats? (Historic flow-rate data or something)
