@shicks, that’s great to hear that you have a bunch of tipping buckets connected directly to the Mayfly. Could you share that code with us? Is it integrated with ModularSensors? It would be very valuable to do that.
I can’t remember all the reasons for developing the TippingBucketRainCounter device application for the Pro Trinket. I do remember exploring lots of options and getting lots of opinions back in the winter of 2018, and my memory was that there were good reasons for not using the Mayfly directly. I’ll see if I can dig up my notes on that.
