I run an ESS system (Venus GX, Fronius PV, 3x Multiplus, Pylontech...) in a system where there is also a RaspberryPi doing additional logging and adjustments (improve self consumption by switching loads for example).
As a system-log over all values (also including domestic heating sensors of homematic etc.) I use a system originally designed to monitor IT infrastructure called "Zabbix". The so called "Zabbix Trapper" can be fed via nodeRed and virtually log and display anything numerically and grahically to and from a database.
I also use a goE Charger to charge a Renault Zoe only from excess solar - also controlled by the Pi running nodeRed.
Would it be possible to also log the consumption of the car to VRM and include it in the dashboard? Means essentially adding a "category" of consumption and feeding this with data logged by the Pi?
