My consmption in graph is zero when PV power is zero. In past I’ve seen consumption values. Consumption forecast is showing.
No one an idea?
In your screenshot Consumption forecast is clicked off.
Sorry haven’t seen your reply. It is not about the forecast. This is working well.
It is about the consumption in past. You can see between 00:00 and 05:00 there is no consumptions in my graph. I have this problem at 2 VRM installations.
Any tipps? Still have this issue.
Please provide details of all equipment at both installations, along with screenshots from the MPPTs, inverters, and any shunt you might have.
Having this information will allow us to better understand the setup and offer assistance.
Dave.
Is this still the issue with VRM Beta?
Perhaps you can also give the FW version of the Cerbo’s?
Is the summary (below the graf)showing any consumption stats?
Also try to deselect all other indicators and have only consumption selected and see what happens.
I’m using Firmware v3.55.
No there is no consumption in this time range. Already tried to deselect anything else. Same behauvior.
Restart cerbos?
And the Beta link for VRM tried?
Already reboot cerbo. Beta link smae behauvior 
Perhaps related?
Maybe, but there is no solution right now?

Could this be related
@cdn: Let me look into this. I need the VRM id (the number in the vrm url) of your systems, before I can check what causes this. And bear in mind that we are about to have a few bank holidays in NL, so don’t expect an answer too quickly.
@Ersus: sorry, misread that remark above and thought that you had the same issue.
@cdn: I’ve found your sites and took a look at the K6 system. That one is running ESS in self-consumption mode, using the battery for the power usage during the night.
If you select the consumption dropdown in VRM, you can see that.
It truly does look like your system is hardly using any energy during some hours of the night. I don’t know the site, so that might be correct. I took the date that shows at relative lot.
If you consume more during the other hours, your wiring could be wrong. It is a bit hard to analyse without having more info on the site.
@dfaber thank you. This is correct. We have a heatpump which is using a lot of energy during the morning.
As you can see there is no consumption data around midnight which is wrong. You can also check another installation (without heatpump but with 48kwh storage). Same behavior.

@dfaber asked me for an opinion. I think it has something to do with the battery, which identifies as a “VT”.
Your grid consumption over night is very low, because you are using the battery. So almost all the consumption comes from the battery.
It looks like your battery has built-in energy counters (it is logged to VRM), but they do not behave as I would expect. They are supposed to be total counters counting all energy taken out and returned to the battery.
Because they don’t behave properly, there appears to be very little energy use from battery as well, which is why your consumption is almost zero at night.
During the day, whatever energy is provided by PV that isn’t accounted for elsewhere is assumed to be consumption. Which is why you have daytime consumption numbers.
There is a workaround. Turn off “Has DC system”. The battery energy counters are only used when really needed (because bad energy counters are a common problem), that is, when there are DC loads. If you have no DC loads, then the energy values are derived from the other energy counters (the solar chargers and the Multi(s) ).
Because they don’t behave properly, there appears to be very little energy use from battery as well, which is why your consumption is almost zero at night.
In location HH28 I have a consumption of about 3kwh per hour. So I don’t think this is very little.
Also I have hours during the day where I will have the same consumption and there I can see it in VRM.
Let me rephrase.
Consumption is the sum of 1) grid, 2) battery, and 3) PV directly consumed by loads.
At night, you consume very little from the grid, there is no PV, and the battery gives you wrong readings. That’s why no consumption is shown at night, even though there is actual consumption.
If you don’t have DC loads, turning off the “Has DC loads” option makes it ignore the energy counters built into the battery, and it will work around this problem.
If you have DC loads and want to account for them, you’d have to talk to the battery maker about fixing the energy counter, or install a SmartShunt.
I hope that helps.
