[image]When I first connected everything the smart dongle showed up on the app but I can’t use it to configure the multiplus somehow.
I tried both port and bought the Victron cable but still not working. Help please!
[image]My VE BUS SMART DONGLE that is connected to my MULTIPLUS reads incorrect voltage, it is 0.59v higher than the input wires at the VE BUS. It is causing my MULTIPLUS not to charge when battery voltage is low. See pictures.

VE.Bus dongle is connected to the MultiPlus, as is the Cerbo. Prior to a recent firmware update for some of the devices, we could:

The only changes to our system have been recent firmware updates. Very confused.

I'm just wondering if having the VE.bus smart dongle and the BMV712 on the same network can cause issues?
I'm particularly concerned about having both communicating the voltage to the network... At least they read the same value!
Also, is there any way of receiving and displaying the temperature sent by the dongle on the BMV display?
Thanks for your help!
What will happen if the VE bus Smart Dongle is connected to a parallel configuration of 2x MultiPlus Compact 24/2000/50 FW 497?
Will Victron Connect connect to both Multi's?
Bonjour , je viens d'installer le VE- Smart Dongle pour piloter un multiplus 800VA , dans l'application victron connect je vois bien le smart dongle mais pas le multiplus . j'ai bien fais les mises à jour mais toujours le même problème .
My system has Multiplus-II, BMV 712 Smart and VE.Bus Smart Dongle. In the Victron Connect app, the battery voltage reads 0.7 V higher than is reported by the BMV, and about 0.6 V higher than the voltage measured directly across the Multiplus-II DC terminals. The Multiplus-II indicates it is float charging, but the BMV shows net approximately 0.8 A flowing out of the batteries and the LiFePO battery voltage is about 13.25 V. When I remove the dongle, the batteries net current is positive a few amps that varies, and the voltage goes above 13.5 V.
It seems this 0.7 V offset is preventing the inverter from putting out the proper amount of current.
Do I need to directly sense the battery voltage on the Multiplus-II battery sense lines to override this erroneous voltage?
I wanted to upgrade my campervan system consisting of a MultiPlus 12/500/20-16 with switch connected to toggle between charging only and invertor, SmartShunt, Battery protector, Buck Boost 400 and Lithium SuperPack 12.8V 100ah in order to allow limiting the input current for shore power so I bought a Ve.bus smart dongle and connected it (just the UTP cable and power cables directly to the Lithium battery with ground through the shunt first). It showed up in the app, found the MultiPlus, showed the data but after about 30 seconds it went to initializing again repeating the process. It also did not allow me to update the settings for the MultiPlus. With this 'reset' I could hear a relay click and see the red and green led briefly blink on the MultiPlus. The moment I disconnect the UTP cable the MultiPlus behaves again. I replaced the UTP cable with another high quality patch cable but this behaves exactly the same.
I'm not sure what else I could try to get this to work, are there any known remedies?
I bought a Multiplus Compact 12V/1600VA and the matching ve.bus smart dongle in October 2021. Unfortunately, the Multiplus that is connected to the dongle with a CAT6 cable is still not recognised in the Victron Connect app on my iPhone.
Temperature and voltage are displayed.
I don't have a Cerbo and have waited longer than 30 seconds. MP is switched on, of course.
I have tried both connections in the MP and also a different cable. I have also had switches 1 on and 2 off on the switch board.
Now the reason could be that the firmware on the MP is too low, but since the device is from 10/21, it should also fit.
What else could be the cause?
I have wanted to be able to control the Multiplus via the Cerbo, but the VE.Bus BMS and VE.Bus BMS Assistant on the Multiplus block the Cerbo from changing the invert state between On / Off / Invert Only / Charge Only.
Having done some testing I have reverted to the 2-Wire BMS assistant on the Multiplus and wired the VE.Bus BMS Charge Disconnect to the Aux 1 port and Pre-Alarm to Aux 2, using an Inverting remote on-off cable. I am now able to change the status of the Multiplus from within the Cerbo Screens. The Cerbo correctly shows the VE.Bus BMS status through the relevant MultiPlus screen. Both disconnected at the moment.
I also had a VE.Bus Smart Dongle and found I could modify the status of the Multiplus via my phone as well. When status changed the Cerbo reflected that changed status. So I have a system working as I would like, but not using any functionality of the VE.Bus. I guess I could have achieved the same thing using the smallBMS with pre-alarm.
What I was wondering is if anyone can advise what functionality I might have lost by disconnecting the VE.Bus BMS from the VE.Bus?
I have noticed during my testing today that there is no Alarm or Error that is logged when the VE.Bus BMS signals load or charge disconnect, simulated by disconnecting the signal. The Cerbo clearly isn't triggering on the change of the Multiplus VE.Bus BMS status. I am not sure if it ever did alarm/alert when the VE.Bus BMS was connected via the VE.Bus port to know if I lost functionality. I do know a few weeks back I had a VE.Bus BMS Charge disconnect event and never saw anything on the Cerbo.
Hope people find this useful and it would be good to understand what functionality has been lost by taking this approach and not have the VE.Bus BMS communicating on the bus.
Hi, I was wondering if someone has an answer. When I look at the Smart Dongle connected to my inverter on the Apps first Screen I get a message "AES - Load below threshold" and the Battery reads 13.85V -0.7A 85% 22C.
On the 2nd Screen under "State" I get the same message. It also says "Grid disconnect reason" - "L1 AC input disconnected" and shows for this reason under AC input L1all Zeros. Under AC Output it shows Voltage 75, Current 0.05A, Power 2 W, Frequency 60.1 Hz. Nothing was connected to the outlets.
Does anyone know what is wrong and what AES load below threshold means?
Thank you in advance for your help.
I am trying to help someone in a remote location connect the victron VE bus smart dongle but there is already something connected to the J45 socket on my multiplus device. This could be a voltmeter or remote control unit but he wants these both left connected. How do you add the dongle?
I have old Multi Plus Compact 12/1600/70 with 2606154.VFD
I would like to connect them with BE.Bus smart dongle.
And set couple variables like:
Max charge into 30Ah etc...
Set search mode ... etc...
After first connect via USB-mk3 I received info that firstly I should to upgrade firmware.
"Current firmware version is v 154 and is not compatible with Victron Connect..... install 415".
So I download firmware:
2606494.vff and install it.
But after that I have battery status "fault" info and LED start blinking ((green yellow) : (reed)).
So I checked with:
and stopped at:
2606159.vff - where Multi starts runing.
What to do with that?
It means that I will not allow to use Victron Connect to set params? Mk3 is useful in this case and VE.Bus Dongle too...
I have just added a VE.Bus Smart Dongle to my MutliPlus Compact in my caravan, and the remote switch (simple 3-way toggle) will not work (ie won't turn the MultiPlus off) while the dongle is connected. If I remove the RJ45 from the dongle it works correctly.
It seems the Smart Dongle is over-riding the remote input. I know I can do remote control from VictronConnect but that's not as convenient as flicking a switch.
DS1 and DS2 are off (as they should be for the remote switch to work). Firmware is 2606430.
Am I missing something?
Will this still be an issue if I replace the 3-way switch with a Digital Multi Control?
Any help appreciated.
