I am about to implement an opportunity load into a Victron ecosystem.
I already have the code to define the amount of power to be derived to the water heater, but I am not sure of which protocol to use, ModbusTCP or MQTT.
I can use both ( as the project is based on a RPi), but I am not sure which of them I should use, as it seems both adequate to my needs of reading variables from the CCGX.
Could you guide me? I have already read the “Data communication with Victron Energy products”, but I found no guidance apart the internet related or not.
FYI: It is for an offgrid system, without WiFi and the connections will be made via an Ethernet cable.
Thanks for your help!
