I have a simple home solar PV system - 2 panels, MPPT 100/20 charger, AGM batteries & Phoenix 24/800 inverter. It's up and running and I've added a Raspberry Pi 3 running Venus OS, connected to the two Victron devices with VE.Direct USB cables. I can connect to the Venus system with a browser and can see the devices data fine. I can connect using the VRM portal and can also see the devices data fine.
I've enabled the Venus MQTT broker for SSL and PlainText and can connect to it from MQTT Explorer but all I see is the following :
I know there is a 'keepalive' requirement I've seen discussed in the forums, but as I understand it the Venus MQTT broker is enabled when accessed from the VRM portal and should be accessible from the LAN when that happens.
My problem at present is I cannot see any data from the two victron devices in MQTT Explorer. I assume I've missed something, but trawled the forums for a while and cannot see what it is ??
My aim is to bridge the central MQTT broker in my existing home automation system to the Venus MQTT broker so I can add the Victron data into my home automation database (InfluxDB) and display it, along with other data, using Grafana.
I've spent hours reading forums posts etc. but cannot see where I've gone wrong. It would be much appreciated if someone could give some guidance as to how I can achieve my aim of adding the Venus MQTT data into my existing home automation system, with the 'keepalive' function and without using the VRM portal. I have no need to se the VRM portal as I have already have VPN access to my existing system, so will be able to see the PV data when added into the system.
