UPDATE - So in the app I turned off ‘true radiant’ and ‘auto schedule’
and it didn’t come in the early hours - and came on at the time I
scheduled it for - HAPPY DAYS!
Well it came on again at 03:50 this morning and woke me up! So started
googling and found this thread on here. What do you all think?
