The issue mentioned in the original post may be back, ( MAC address: 44:67:55:40:61:1f ). It did work for a few smart watering sessions after the firmware update. Then we had a few rainy days and a rain delay was activated, and the next smart schedule was last night 5/22/18 at 8:00 PM. The watering did not occur it simply rescheduled it for today (5/23/18). So are there any issues with smart watering activation after a rain delay expires?
In case it matters I did have to power cycle it once last weekend. It disconnected from WIFI and would not reconnect on its own with out a power cycle.
