Re my post 4 Apr 17 above re Power issues - I missed the post on the other topic about resolving the reliability issues:

I had reliability issues for a long time, resolved before I started using the feathers. My problems were with wdt resets. I narrowed it down to what I am convinced is a problem in the interrupt handling of the Arduino/ESP8266 core. I stopped doing what I was doing to cause it and now the devices - either the nodeMCU or feather - run indefinitely without exceptions.[/quote]
