HI there,
So, I’m doing it this way. When I do the “Get” from the weatherAP and also when I do the Forum “Get” They both return Payload with a Time stamp. I use that and the time since I “last checked” and test for sameness…
IMO , the RTC isn’t 100% without the interrupt.
I’m betting they are going to make and offer more of these in the future , hopefully they listen to the user base and tweak up the design
