Finally Picked up a few G6's. Still on the G4 until next year, but I had a chance to get an ESP32 to talk to the thing. So, hopefully, when I finally have to downgrade, I can at least keep the functionality I want.
New device, ESP32 TinyPico, total size 1 3/4 square and about the thickness of a cell phone, perfect. Battery life was around 17 hours, it's a power hog. Nice feature is the pico has onboard lipo management ie. charging.
