Connecting BMV712 and MPPT to wireless for remote monitoring

I have an MPPT and BMV712 that I’d like to connect to my van’s wireless so I can monitor things remotely. Is this possible? What additional hardware would I need?
thanks

Hi @Neal Haddaway. You can use a color control GX or a Venus GX, which will then link to VRM which you can use for remote monitoring of live and historic data. You would need a ve.direct cable for each of the MPPT and battery monitor. Unless you have a CanBus MPPT, in that case you’ll need a RJ45 cable for the MPPT.

You can listen to the serial VE.direct-Informations by using an Arduino (or an ESP8266 - with WLAN). You can find a library to do that in this forum. These informations can be shown on a webpage provided by the Arduino/ESP8266 or it could be transfered to a "Smarthome" solution...

This would be very cheap and simple...

Even simpler, you can also just use a cheap RaspberryPi which will run VenusOS directly and allow the use of VRM.
