Same question: I would like to use Shelly 1 in my car... But when it chargibg from generator (in working engine) it is above 14 VDC (14.3, 14.4 Volt)...
Could I use it for? Or is there any (other) solution?
Same simptome. The device working I can get information and connect via middle ware server (behind my firewall) - works wry well, but the shelly cloud app and my.cloud web site is say it off line.
When I reboot, a few minutes goes to online.. after nope.
