Hi guys!

I have a problem with my ioniq 28kwh car, use ovms over 2 years, and now
drain my battery last day i found the following, if i set the vehicle
module to none, the drain is stop. i use the edge fw.
In night the auto update fw is run and after the reboot the battery drain
is continue. In the picture can see, 15:15 set vehucle module to none,
 auto update is run at ~3:02 (vehicle module to hyundaivfl) and i woke up
at ~5:20 and set the vehicle module to none

I attach a log and a screenshot of battery voltage

What can is do? Problem with a OBD cable? I detached the ovms from the car
for a couple off hours but when is reconnect it not connect to the wi-fi
network, but when i connect a computer or a powerbank, the  wi-fi
connection is established, after usb disconnect network works fine, but i
have many can errors.
On charging i get many ovms messages, charge stopped, started.......
