Smart watering stopped scheduling watering sessions for me in Mid-May. I too have switched to manual watering. My “test” waterings are showing up in the history. My % moisture is registering after I run a test watering. Right now, all my zones are showing 0% water except the two I did short tests in. My watering history shows nothing for about 1.5 weeks which may explain why the moisture content of most of my zones is 0%.
My theory is that something has stopped running on Orbot’s cloud service for all of us.
