I haven't received any notifications in months. My internet is super stable. Not sure what I'm going to do.From my experience , It was slightly delayed (30 seconds) last week , but in the last few days back to nearly instantaneous.
I am wondering if load shedding is causing crap with them if they being powered off or that the internet connection itself dies and comes back up with a new IP.
Now that loadshedding won't happen this week, if you haven't tried, power off ip150 and back on. If the internet connection is stable then hopefully you get instant notifications again? Just a stab in the dark
