Understandably, I suppose there's not too many other dingus's like me that have then successfully remedied any backward installed battery holder... I'll keep fiddling and report back if anything gets her back in proper working order.
I'm having an issue getting my iSpindel to run correctly with the battery installed. When I switch it on, it pings to Ubidots and goes to sleep, but when it wakes up it just stops and I get a solid blue LED on the Wemos. It works fine with the battery removed and the WEMOs USB plugged in...
