Globallink 520 data in VRM incomplete

So sad threads from the old community haven’t been copied. Even worse new accounts are required.

Ok, ontopic: Several graphs in my VRM show massive data gaps. In the exported files the data is missing as well. Just have a look at the BMV-712 graph:

All is logged fine, except from the temperature. Similar with the Orion-XS or Smart Battery Sense, both not being logged properly:

Strangly, the current is being logged flawlessly. But not voltage and temperature.

Anyone having the same issue? What’s wrong here? In my old post quite exactly one year ago you can see some gaps, but now it’s even worse. Makes it unusable from my standpoint (Gaps in VRM graph drawn by Globallink 520 data - VictronEnergy)

We had a quick look at the debugging data since this did indeed seem unusual, and concluded it looks like it’s a combination of three separate things:

  • Your “starter battery” has quite bad Bluetooth signal; about ~40dB worse compared to your other BLE devices. It looks like the GlobalLink can’t always receive the measurements from it and that’s why the data is showing gaps.
    • Try moving the GlobalLink and/or the battery if possible and making sure there are no obstructions between them that might affect the Bluetooth signal.
  • The temperature data attribute is not send every 15 minutes. Only a subset of all available data attributes are send every 15 minutes by the GlobalLink, and the battery temperature of the BMV-712 is not one of them. That is why the temperature of your “leisure battery” is showing gaps.
  • The “DC/DC charger” is actually within range of the and the signal strength looks fine. However, it looks like the GlobalLink is unable to decrypt the data coming from it; perhaps you performed a factory reset on it or changed the Bluetooth PIN code which caused the encryption key used for Instant Readout to change. That is why the data from your Orion XS is not showing.
    • To reconnect the Orion XS to the GlobalLink you’ll need to connect using VictronConnect to first the Orion XS and then the GlobalLink so that VictronConnect can transfer the new encryption keys and the GlobalLink should once again be able to decrypt the instant readout data coming from your Orion XS.

Thanks Daniel.

Strangly, the Battery Sense is in reach for the BMV, MPPT and Orion. These and the Globallink are close to each other in the boot.

Then I‘d rather try to move the latter to the middle of the vehicle to get closer to the starter battery

Will try the re-coupling of the Orion on the weekend and gibt you a headsup.

Sorry Daniel, but I need to undermine your argument. Look at that:

The BMV-712 is 50cm away from the Globallink.

What t f is going on here?

Re-connecting the DC/DC Charger worked. But look at the Voltage (DC/DC) and Current (MPPT) graph. There is a data point, but it’s not been drawn.

There is clearly something wrong with the VRM web app.

And after one day of working, the graph and data points disappeared again …
