Graphing stats from a remote solar MPPT charge controller
Goal for this Hackweek
At the end of the hack week, we should be able to access data in realtime from the MPPT controller.
Resources
The setup is pretty simple:
an MPPT controller (plugged to solar panel). The brand is Victron Energy https://www.victronenergy.fr/solar-charge-controllers/mppt7510
a RPI 1(the only left I have) running the OS
an old Android phone USB connected to the PI for 4G connectivity
a VPN, providing access to an MQTT service
the graphing part will be done through Grafana
The MPPT controller already provide stats through a proprietary bluetooth connected app. Unluckily, the protocol is kept close by the manufacturer.
We should be able to get the stats through a 3 pins I/O ports connected to the RPI GPIO
Victron opened a bit its protocol so we should be able to get data from it.
Some new devices appeared on my setup which are also broadcasting data on bluetooth. Let's try to get those as well.
Looking for hackers with the skills:
