i have OMVS in my MG ZS and it worked great until two things happened at once:
first an online update happened by itself, the app told me
then the car had to go for repair and was not used for over a week causing a dip in voltage of the 12v battery and OVMS stopped. I disconnected the negative pole on the 12v battery and recharged it.
When I reconnected the battery percentage no longer shows on the app. I have tried deleting and reloading the app. No luck no tyre pressure either but the gps find my car is working
does anyone have any ideas what is wrong?
