I’m using the Smart IP43 charger to support my Multiplus II. It bothered me that there’s no Victron Node for adjusting the charging current. I want to set it variably. This is easily done via MQTT.
Using the slider, I provide five values to choose from. These are then processed in a function node:
The payload of the function is fed into the MQTT out node:
The charger then switches to the new charging current. This can also be seen in the MQTT Explorer:
I’ve limited the values to 0A to 25A. Have fun testing!
