I have three Victron Multiplus II 5000 inverters and have been testing the latest Beta (3.60_25) with virtual devices. I’m sending my Grid Meter data via MQTT to Node-RED, which then forwards it to a virtual Grid Meter. This setup works well.
However, I noticed that if the virtual Grid Meter gets disconnected or no data is transmitted, the Multiplus does not switch to “Passthrough” mode for safety reasons—not even after more than 30 seconds. I tried implementing logic in Node-RED to change the virtual Grid Meter’s status to “Disconnected” when no data is received, but this had no effect on the Multiplus behavior.
Has anyone else encountered this issue? Or do you have any recommendations on what I should change?
Is the grid meter configured, or able to be configured, as one in the GX settings for ESS? While VRM knows about a virtual device, if the system is unaware it is unlikely to work. The joys of beta testing
well it shows up in the overview as Grid (Netz) and the values are the same as the ones in MQTT. In the ESS settings it shows external Meter (Externer Zähler).
Also if I disconnect MQTT, the values in Grid (Netz) will stay at the last value transmitted through MQTT. So looks to me that it is considered as the Grid Meter in the ESS.
Ok, then I suspect that the system doesn’t currently recognise that it has been disconnected as the virtual node is likely still connected, despite it not receiving any data.
Not sure what that involves to resolve. @dfaber
