VE.Bus BMS verses smallBMS and signalling charge disconnect to MPPT controllers

As I continue to investigate the possible connection options to get my system working as I require and following on from my question about VE.Bus BMS verses smallBMS. I hope someone can help with this part of the communication flow and if any functionality is lost be using a smallBMS verses a VE.Bus BMS.

I am aware that the Cerbo is able to signal via VE.Direct or VE.Can to connected Smart MPPTs that a charge disconnect event has happened. This is confirmed in this post where Guy has stated "Yes, it works. The VE.Bus BMS will signal to the Multi on the VE.Bus, and then that will be sent to the GX device which will control the MPPTs via or VE.Can (>2019 models only) cables."

However there is nothing about the smallBMS. The above post has a link to another post where Matthijs says "Regarding connecting: the Venus GX cant retrieve data directly from the VE.Bus BMS. So, even though they are on the same network (VE.Bus); you still need an inverter/charger in that same network to make it work.". This implies to me that the MultiPlus sends the charge / load disconnect to the Cerbo and not the VE.Bus BMS itself.

While I have a VE.Bus BMS at present it is not connected to the VE.Bus and I am using a 2-wire assistant on my Multiplus. The Cerbo shows this and when the pin on the VE.Bus BMS goes high, the Cerbo state changes too yes. So I know the Cerbo is getting the information.


So the details are getting to the Cerbo. Therefore with a smallBMS or VE.Bus BMS using 2-wire assistant, will the MPPTs still get a charge disconnect via VE.Direct or VE.Can. I am unable to test at the moment as while my MPPTs are installed the Solar panels are not yet installed.

I would like to know if when using the smallBMS, the VenusOS will still signal charge disconnect to the MPPTs, and how I can tell if the signal is getting through to the MPPTs. For info I have two VE.CVan 150/70's connected via VE.Can.

DC current or energy measurement with Venus GX

In an upcoming project there will be a need to measure DC current up to about 90 A also from sources that are not controlled with Victron equipment and/or to loads. Does anyone know how to use a DC current sensor or DC energy meter with Venus GX/VRM? I would like the system owner to be able to monitor at least the DC current (A), but power (W) and/or energy (kWh) would be even better.

I have seen that some AC energy meters are supported by Victron (, but I can presently not find any DC energy meter listed there.

Example of DC energy meter, which seems to be available e.g. with Modbus TCP communication:

Example of USB current sensor:

Example of current transducer that I have good experience of from other applications:

Cerbo GX FW 2.60 and GX 4G Connection Issue

Hi All,

I installed a GX LTE 4G today and found that an icon was trying to display on the top right by the clock, and that the system was reporting internet Offline, when the system was clearly online and communicating with VRM. See screen shots

I also logged in via ssh and found that the ppp0 interface had received an IP address and was able to do DNS lookups and ping.

I wasn't able to do any further investigation. Since I have got home what I have noticed is that the location symbol moves one to the right and back again.

Issue with 4G/LTE provider assigned (non public) IP address

The issue I have is that my provider (Base - Belgium) don't put the IP address public available and every 4 days, they change the IP address, what results in the Venus and router (M1 Nighthawk) has no longer internet access and also no remote console from the VRM. The solution is to reboot the router or via the admin console of the router to switch off and back the data. But when my RV is stalled at 30km from home its require a drive back and forth, so I consider the physical reboot as not a viable solution.

I want to understand the technique of the bi directional data exchange with the VRM.

I wish to know if somebody else has the same issue and how it has been solved.

What Alerts does one get from a VE.Bus BMS connected too Cerbo

I am after some information on control signals and information flow with the VE.Bus BMS environment.

I have read the following post and done my own testing

This has highlighted that the MultiPlus/Quatro is key to the interworking. While the Venus OS, Multiplus/Quatro and VE.Bus BMS are all connected on a single VE.Bus BMS there is dose not seem to be any information that flows directly between the VE.Bus BMS and Venus. It all flows through the MultiPlus/Quatro. Therefore it is the Multiplus/Qutro that is reacting to messages from VE.Bus BMS and passing information onto the Venus OS. The Venus OS is then able to pass information to VE.Direct or CAN.Bus connected MPPT controllers to disable charge.

What I would like to know is what functionality if any is lost or gained from using a MiniBMS or VE.Bus BMS with the 2-Wire Assistant verses using a VE.Bus BMS with the VE.Bus Assistant. I know the outcome of both approaches will be that the Multiplus/Quatro will be told by the BMS to stop charging or inverting, but what else is going on behind the scenes that would make having the load/charge disconnect on the VE.Bus?

Many Thanks

VE.Bus BMS and MultiPlus / Cerbo combination

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.

How to reset SOC to 100%?

There is one past thread about this issue in which I participated, but it seems the recipes mentioned (and that I've been using) for some reason don't work anymore:

For the last weeks I never got my system to show 100% again (or 85% for that matter). I've set MPPTs to have absorve voltage higher than what is set on Multiplus, I also made sure the absorption time was higher, but nothing seems to work. Never get to the 85% or whatever is set on the Multi.

I have run out of ideas...

My system is Venus based, no BMV, but no DC loads or charges.

Current Multi Settings are like this:



MPPT vales are what you wish.. tried even with 28.8V in absorption today.

See graph:


Why can't the SOC be recognized as 90% ?

Venus is running 2.60, not since too long ago. Could be something within Venus OS?

I also tried Multi connecting to GRID -> Goes straight to FLOAT, SOC continues at ~30%

This is an old issue... but for the moment, besides trying to figure out the root cause for the system not resetting every day to 85/90%, what I would like to ask now - as a workaround - is how to manually force the system to reset to 100% ?

I used to do the trick of commanding the Multi to Equalize from Grid and then Interrupt -> go to absorption / Float. It used to reset to 85% (that was at the time set). But now even this is not working.

SmartShunt with VE-Direct to RPi Venus and VE.Smart Networking to MPPT ?

I ordered a Victron SmartShunt 500A/50mV as BMS in a TinyHouse.

I have a Smart MPPT 100/20 and a Victron Inverter Phoenix 24/800 VE. Direct, both are connected to a Raspberry Pi 2 Venus with a VE.Direct to USB interface for logging to VRM online portal and onsite lcd screen for insights.

The SmartShunt will be connected with a VE.Drect cable and VE.Smart Networking.

The idea is to use a VE.Direct to USB interface from the SmartShunt to the RPi, so that with the setting: "has DC system" the total DC load is measured and also know the SoC of the battery.

Then also use it with a Smart Network to the Smart MPPT.
Like in:

In the manual: "A VE.Smart network containing a SmartSolar with temperature sensor and a MPPT solar charger, the solar charger receives the battery voltage and temperature information from the SmartShunt and uses this information to optimise its charge parameters. This will improve charging-efficiency and prolong battery life."

I want in the future use a Victron Energy Smart Battery Sense (mainly for temperature compensation) so that the aux input port on the SmartShunt can be used for midpoint voltage.
Can the Smart Battery Sense use the VE Smart Networking and the MPPT and the SmartShunt too also to use this temperature setting?

I want also make a VE.Direct cable connection to Venus and also monitor the midpoint voltage of the battery bank (cable included); 2x 12v in series. Is it possible to use VE.Direct cable and VE.Smart Networking at the same time?

How important is the temperature sensor? The batteries are below the roof, so in the summer there are possible high temps (> 35 celsius) and in the winter low temps (-5 < 0 celsius).

Other questions about settings of the SmartShunt:

  1. 7.1.1 Battery capacity
    With the Battery capacity setting (manual 7.1.1 Battery capacity) you set a parameter for how big your battery is. But there is no indication in the manual for what C-rating this setting is. Is it safe to asume that the setting is for a C20 rate?
    For my Victron Energy AGM Super Cycle battery (BAT412112081) this is than 125Ah

  2. 7.1.2 Charged voltage
    The Carged voltage setting is 0.2v or 0.3v below the float voltage.
    In the battery datasheet: "" the float voltage = 13.5 - 13.8
    (would be nice as the datasheet gives an one voltage instead of a range).

    Assume float battery voltage of 13.8 x 2 (batteries in serie) = 27,6v - 0.2v = 27,4v for charged voltage setting. What is better, to low or to high?
    The manual has a default of 26.4v Why so low?

  3. 7.1.10 Battery starts synchronised
    The batteries aren't fully charged due very clouded weather for continious days.
    So the best way is not to set the: Battery starts synchronise (manual 7.1.1) in the OFF state?

  4. 7.1.7 Charge efficiency factor
    The batteries are 2 year old. How te measure the current state of the battery? Maybe it must be less that 95%?

  5. 7.3.2 Temperature coefficient
    What is more importand, to use the aux port for temperature coefficient or for monitoring midpoint of a battery bank (2 batteries in serie)?

Sorry for the long posting, but I hope this makes the use of the SmartShunt more clearly for all the Victron Energy users around the world.

Looking for input - 4 to 20mA and 0 to 10V senders

Hello Community!

We’re considering to add a USB accessory to our GX product range, to add 0 to 10V, as well 4 to 20mA inputs.

But since all of us have very limited experience with 4 to 20mA tank senders, we're looking for some input:

  1. Is it always 4mA = tank empty, and 20mA is tank is full? Or do the empty and full levels need to be configurable in a software setting on the GX Device?
  2. And how important is it that the transducer can be powered by our device?
  3. Anything else we should keep in mind when designing a 4 to 20mA input? Good features you have seen else where?

Also, if you are using 4 to 20 mA senders, please post a link to a datasheet or specs below. And if you have an opinion on the sender, what you like/don't like, welcome to add that.

Lastly, most questions above are for 4 to 20mA, not for 0 to 10V - but if you have special comments about 0 to 10V, welcome as well - obviously. The product we have in mind will have inputs that can be used for both types.

Note, that this is quite early in the product development, I can’t say anything for now with regards to availability dates.

All the best and thank you! Matthijs

ps. just to prevent any question about this: we'll soon launch a new Venus OS version that can work with irregular tank shapes, as well as naming tanks and some more features: all those features will also available for the 0 to 10V and 4 to 20mA inputs. Details here.

Importing data on raspberry pi venus os


I want to monitor the water level in a well 10m away from the raspberry pi. Until now I had 2 reed water level sensors connected on the digital input pins on the pi.

Because the sensors are quite unreliable (the connection) and wanted better precision I have mounted an ultrasonic sensor in the well and with a small arduino I know the exact water height.

I need to monitor the water level because the well is not very deep, the refill rate is slow and I want to remotely start the irrigation system - I don't want to run the pump if not enough water.

I was thinking of converting the ultrasonic output into a voltage to be fed into an mcp3208 adc but surely there must be a better way than all that data conversion and more locations for errors to be introduced.

Maybe serial communication between arduino and pi? Maybe using an esp module to publish the data somewhere on the web and fetch it on the pi?

Is it even possible to display that data on the victron GUI? Do the tank level menus show up only after activating analog inputs?

Does anyone have a better or simpler way?

I know it's a very specific problem but I'm stuck and my only hope is this community.

Sadly my python skills are non existent but I always thought that with enough determination and Google anyone can achieve impressive goals.

Any help would be appreciated and thanks for reading

Orion TR Smart woes. Not impressed.


I have three different Victron DC systems and had plans to add the Orion TR Smart to two of them. I purchased a 12v 30a non-isolated Orion TR for my RV and to bluntly put it.. I'm not impressed.

This device has no connector, what is the logic behind this decision? If I've invested the money to control every aspect of my Victron system through Venus, why would this device be headless? There also seems no way to add it into the bluetooth VE networking protocol.

I have come to rely heavily on DVCC for my dynamic charging needs, so the fact that this device can only be controlled through bluetooth with an extremely limited set of configuration options is frustrating.

The bluetooth radio in this device is abysmal. I can control every other Victron Smart product meters away from them, whereas this Orion TR doesn't even broadcast outside of the vehicle it's in. I have also seen similar complains in the ratings sections of a retailer and on this forum.

Has anyone used the external relay control features of their multiplus or possibly bmv-7xx to provide at least some type of logic-based control to their dc-dc charger?

I feel like this device was rushed to market. I am struggling to see the value in the Orion TR, I am considering returning this item. Does anyone have any insight if there are firmware improvements scheduled for this product or if I'm missing something here?

Where is the DC power usage coming from ?

I have a Mastervolt Chargemaster plus 24/60 charger, 100 x 4 lithium batteries, a Victron BMV-712, A Cerbo GX, Cerbo HD Touch and a small Victron Phenix 250w inverter (only for TV´s and stereo) in my setup on my boat.

The inverter is NOT having any load. All connected devices is OFF and the Cerbo is showing 0 load from the inverter.

The BMV shunt is connected after the batteries before the load and the charger.

In the picture you can see that the batteries are full and that there is NO load (0w and 0.0A) from the batteries. So to the question: Where does the DC Power of 69W coming from ?

I understand that the Inverter can be using upto 8 watt in zero load, but there is a big difference between 8 and 69 watt ;)

Help with controlling/configuring system

I'm an off-grid camper, and bought the following victron components from a distributor that only works monday through friday. I'm 400 miles from the camp location during the week, and due Covid-19, I'm lucky if I get a Saturday to drive there, let alone a weekday.

I used VictronConnect to configure the Smart Solar VE network, which is receiving info from the BMV.

Here's where I get confused.

Question 1:

The VE Smart Network in VictronConnect shows the connection between the BMV and the Solar Charger, but why does Venus report?


Question 2:

Why is the SOC always reported as -- on the Multiplus screen in the Venus:


Question 3:

How can I shut the inverter down when the SOC reaches 50% to save the batteries? There's got to be a simple reference to show how to hook up the bmv to the multiplus, but I can't find it.

Question 4:

Would the BMV feed data to a second Smart Solar charger if I add one in order to expand to 600w of Solar?

VE.Bus BMS and Multiplus, remote switch off off Multiplus

Good afternoon,

Is there any configuration or assistant that can be applied that will allow for a remote switch off of the MultiPlus when used with the VE.Bus BMS and Cerbo GX. I know that in this configuration a DMC will allow this to happen, but I really do not want yet another panel to install (cost and space). I had hopped that a switch between the Left and Middle pins of the remote switch on the main board would work, but no luck. I am sure at some stage the ability to turn the inverter on and off through the Cerbo will be available, just as it is when no VE.Bus BMS is used.

My reason for asking is that when I leave the boat the MultiPlus, even with AES applied has been the biggest parasitic load causing a drain of 158Ah in just a week. Having turned the Multiplus off at the switch on the front the parasitic load has dropped to just under 0.2A. With the Multiplus on and in ~AES Search mode the system was drawing between .4A and .8A, occasionally going as high as 1.2A.

OK, I know I can turn the inverter off on the front panel, but that is a pain due to it's location.

I would connect Charge Disconnect from the VE.Bus BMS to Aux Input 1 and set the assistant so when open the battery is full and force to float. Then connect Load Disconnect to Aux Input 2 for battery is empty.

Would this work?

Webhooks on VRM API or GX - Alerting on Grid Loss

Given the ongoing local grid instability and perennial rolling blackouts in South Africa, we really need a better way than email alerts to signal a grid loss.

We're currently developing a small daemon to run on the GX device to catch a grid loss and trigger an event remotely but that will require us installing that custom code on every GX device we ship and that's going to be harder than it should be.

Two solutions come to mind:

1. Allow calling a custom webhook directly from the GX device on grid loss.

2. Allow calling a custom webhook from the VRM API (configured for the site inside VRM) on grid loss.

I would prefer the first solution because it would not be delayed by the reporting interval configured on the device.
