Hello, i’ve noticed that the consumption forecast in VRM is much to high when i have charged my EV in previous days. I do automatically enable my wallbox when grid current is cheap. I do not charge my EV from the Battery. I dont have an intelligent wallbox, it is simply enabled from a shelly when …

That’s right. I’ve made two observations in this context. First of all, the low price times repeat themselves relatively regularly, so I don’t think it’s a bad thing. The second effect that I’ve observed (2 wall boxes and 1 heat pump that charge directly at low prices), due to the slightly higher co…

I have the same remark as Johann and also run my heatpump and ev charger on the lowest hours, and it influences my system negatively. VRM predicts the consumption during the night based on nights when the ev charger was running. It fills up the rest with battery charging to use during the peak tim…

This would be also my favorite solution. Then i have complete data logging in VRM for later analysis but the forecast ist not influenced. Workaround would be to send my grid meter readings (which come over MQTT) minus the power measured at the EV charger. But then VRM would not see the full energy …

As per a previous post of mine I would still like to see the option for a User defined consumption profile. That way a one off high consumption is not going to distort future forecasts. Also if I know that I may have a particularly high consumption the next day I can alter the profile accordingly. …

The Problem still persists in 2026, is there any Info? Meanwhile i added a shelly to measure the EV consumption and feed the power and energy measurement into Venus OS using MQTT using: [image] GitHub - mr-manuel/venus-os_dbus-mqtt-ev-charger: This Venus OS driver gets the data from …

is this still the case? I’m searching for a solution, DESS without EVCS data

Do you mean me? I still have the issue.
