I switched to Smart Watering (instead of my manually scheduled situation I was reporting above) and noticed a different (but related issue) issue:
App currently shows 4 Smart watering events tomorrow starting at 5am. Good. Looking at the techsupport.orbitbhyve.com site for the device things generally seem to agree (i.e., programs say 4 waterings to start at 5am). However, the Next Watering Says: Programs at 02-07-2106 01:28. This is obviously an invalid value and perhaps is a special sentinel in the software to signify Smart Watering is in effect. Thought it should probably agree with the scheduled watering.
Sadly, this is the time of next watering reported by Alexa when I ask her. 🙁
