Since my current expansion, this week, I have now one: “BMV-712 Smart”. A “battery computer”, which shows everything possible, stream in, or out and how long it has been, etc.. Also a logfile is created, which you can look into the past. What I miss very much is the function that the mobile (so it remains in the car, but I always have such an ancient ipad in the car) sends every 24h (or configurable) a mail with the data. As for example the fritzbox, if you have the of course it’s great that I can read my data on the car, comfortable with BT, but it’s really great if it’s done from afar. I’m not a fan of cloud, but an email every 24 hours with the battery status, that would be great. Someone has a solution for it, maybe even with a raspberry. The solar controller (from the same manufacturer) can pretty much do that, but also don’t see that he would send his log as mail. w
