In my case, I still am not seeing the dev-node node return correct output. This morning I got nothing back, which implied something was happening at the SmartLife Air side. The state changed, the device turned on/off. But the output never happened. After, about 2 hours, started to randomly get output ONLY after I did a deploy of a changed flow... which is really odd, implies that the node initialization sequence is flushing a buffer or something? But the device state reported in the output was wrong, if I turned on the device, output reported off, and if I turned off device, would report on. Will be interesting what the guys at SmartLife Air come back with. I even checked my local network, WiFi, etc. Nothing seems a miss. Until now SmartLife Air nodes have been rock solid and consistent, much better than any other smart nodes I have used before.
