Stephen, as you can read from my reply to you on this post – https://bhyve.orbitonline.com/topic/notifications-on-android-phones/#post-77267
my phone is correctly set up (I have been googling a lot about android pie & notification issues).
My mac address is 44:67:55:04:50:2B
The app updated yesterday but my smart watering won’t run until 8 days time.
I have set up a zone to water this afternoon at 3.30pm (26th April Australian Eastern Standard Time) and will report back with result.
