Had the ohme pro fitted last week all relatively straight forward about 3 hours to complete. No feeding through walls in my case as meter is outside and i think a 5m cable from carger to reach car App is fairly easy to set up as well.
I have an outside metre too (80 amp fuse but only 5 years old) and my fuse box is inside but near that wall the meter is on.
Does that mean I might get away with no drilling too? I thought they had to go to fuse box (or is this where a small extra box is added in meter box?)
