OK it seems I am getting the notifications away from home and not at home connected to my wifi. I have an Iphone 5s and ios 11.4.1 up to date.
While on wifi I have to go history to see if it watered. I can’t check it now as I am out of state and will have to rely on it’s reliabilty. It did notify me of the last watering while I’m away which is good so far.?
