Car battery monitoring

[vanman1936]

Want to be able to monitor my car battery remotely (Bluetooth fine).

From a brief bit of research there are various wired in devices or an obd plugin that also serves as a code reader.

Any recommended solutions appreciated.

I bought one of these about a year ago and it's been connected ever since (to a sadly seldom used car).

Seems I paid just over a tenner with shipping so the price has come down a bit.
Seems to work ok but I don't get any history from it, it only gives me the battery voltage at the point in time when I connect to it. For a few quid it might be worth a go?




Alternative link as the first one doesn't seem to work anymore.
