I think I'm too underpowered for the cold weather. Anything in the -20, range, the LED's flash on and off on initial start up for a minute. Then it warms up and works. Seems to be the Wifi card not liking the cold.
Options, run constant 5v to Wifi card via usb-c or increase the amperage with new power supply and a larger utility box to hold it all.
Damn, I thought I had a nice compact unit.
