Will the VE.direct LORAWAN portal report and display separate voltage readings for both (each) battery banks when a BMV-712 is configured in a dual bank? Though I may be mistaken, the portal demo does not appear to have a sample of BMV-712 dual bank data readings. Thank you.
Hi @Admin :o),
yes the BMV712 2nd batteries Voltage is reported to VRM. You can even view detailed graph info from your second (starter) battery in "advanced" tab on VRM.
Edit:
I just read through the LoRaWAN manual, and it seems like, that the BMV712 starter battery voltage is unfortunately not transmitted to VRM portal via LoRaWAN but the manual is indeed not very clear on this.
Maybe a Victron Staff Expert can confirm.

Thank you for the reply and I understand what you’re saying. However, as the portal isn’t working (in my case) as you describe, I’ve attached some additional detail from another post I added seeking answers to this question. Please see below:
The starter battery voltage graph on the portal is enabled via “advanced”, but shows “no data to display” (it has no actual reported voltage data readings but the empty graph itself is there).but on the 712 device itself (the gauge), it shows the Starter Battery voltage accurately. The primary voltage is showing correctly on the portal and on the 712 as are many other reporting fields/elements,, but it appears that starter battery voltage is not reported over the LoRaWan to the portal. Is this a LoRaWAN device configuration issue or is it a design limitation of the LoRa device reporting? Starter battery voltage reporting is required in this installation in addition to the primary bank voltage reporting.
Oh I see. Thank you for the information. Have you updated the firmware of the devices involved to the latest version? If yes, I will ask an Victron Staff Expert to join that question.
The BMV-712 Smart is at Firmware v4.01. The VE.direct LoRaWAN device is at FW v1.05 and does not appear to to me to be firmware upgradeable via Victron-connect. The documentation isn’t clear to me as to ways to upgrade the LoRaWAN VE.direct firmware with only the two devices (the 712 and the LoRaWAN device) in our Victron equipment environment. At any rate, I believe the 712 is running the latest FW (v4.01) and ill gladly take guidance on upgrading the LoRa FW if v1.05 isn’t the latest. Many thanks for the follow up and support.
I saw that in the docs as well and agree it’s less than clear. I’ll hope for confirmation one way or another from a Victron SE. Thank you for your efforts.
