I got an Virtual EVCS wired using NodeRed. I’m taking data from my JuiceBox using juiceboxproxy, publishing to MQTT and using NodeRed to create a virtual device and forward the charger’s data to this virtual device.
I’m able to see the device data properly as a Widget, but what I’m not seeing is an increase in load consumption.
My EV Charger is connected to my main breaker, so it’s NOT going through the EM530 Grid Meter that covers the rest of my installation. My idea was that I would be able to add it externally and that VenusOS would be able to adjust the installation’s power balance when the charger reports a load.
Is this possible, or do I have to rethink my strategy?
I cannot get the data cable to reach all the way to the main house breaker in the garage. The auxiliary panel in the garage is the one that hosts the EV Charger. It’s the only circuit that’s on that panel, but it falls outside my main house panel, which is the one with the Grid Meter. Unfortunately I cannot find a way to make this better right now…
After playing around with the charger a bit, I noticed that the charger it IS counting on the overall consumption. I don’t know why it’s not showing up as part of the instantaneous data, but it does show up in the totals, albeit not scaled properly (for example it should have said 23kWh instead of 230kWh).
Virtual EVCS is not counting towards consumption, it only shows visually from VRM portal. A Virtual Grid Meter is counting towards consumption, but in my previous image, the units were wrong so it was overcounting.
So what I did was combine these two virtual devices, one that shows it visually on VRM and one that counts. They use the same data, now with proper scaling, and this is showing in my consumption graphs, which is ultimately what I wanted to do, as I was unable to measure at the entry point where the charger is located.
