The VanMeter is a little add on for my camper van for measuring the power consumption of up to four different things. Here I am using it to measure the power of all the loads in my van, the solar panel power and the power of the 230V charger. There is another channel which is currently unused - or as you can see in the end of the video, was used to measure the correct voltage (differential measurement) of the solar panel. Unfortunately I didn't find the solution so far, but I would be happy if you have a hint for me.

There are two more things which I haven't shown in the video. The first thing is that I have used the ESP32Remote ( https://youtu.be/5vRy--YCx7k ) as a remote display next to the phone APP. The other thing is that the VanMeter can not only measure power consumption, but also is able to control up to eight different outputs. The pinheader on the right side of the PCB is optimized to be used with one of those eight channel relay boards. These can be used to control lights, outlets, pumps, heater elements or whatever you want. Something like a smartvan.

As you have probably noticed, this build is still a work in progress and some features are not yet implemented. Some other things will be added to this board in the future. So stay tuned!
