Hi,

I am looking for a possibility, to grab data from some Victrons (BMV, MPPT) via BLE for further usage in homeautomation.

Victron said, they will not publish BLE documentation

@mvader (Victron Energy Staff) answered me, i should post this Topic here...

I started looking at the BLE Interfaces of BMV712 and 3 different MPPTs

Till now i found, that the Service UUIDs and the Properties (of the 4 devices) are _absolute_ identical !

I started sniffing the BT Communication between ‚Victron Connect‘ and the devices...

The Logs are actually available in TexasInstruments SmartRF sniffer format (.psd)

I would apreciate finding somebody, to share Knowledge.

I am sure, there are some people outside, also interested in this topic.

And perhaps we can coordinate it here in this Thread ?

Regards stefan

Hi, I have read this page: https://www.victronenergy.com/live/victronconnect:mppt-solarchargers#load_output, chapters 4.2 and 4.5 but I am not sure about this question.

I want to use an arduino/esp8266/... to log data from my MPPT 75/15 solar charger controller.

So I need to connect TX and GND pins to my arduino.

I want also use the RX pin of the MPPT to control load output state from my Arduino.

Is it possible? What will be the correct settings in the MPPT?

And for Arduino, I have to output down RX to 0V == switch load output off, and to output up to +5V == switch loadout on .

But what about this sentence: "(or a signal sent via VE.Direct communication)". does it mean that I could write and HEX command to RX to switch on or off my MPPT load output?

If RX could recieve signals, I understantd the MPPT have to "wait" time to confirm the pull down or up of RX that I have said in previous paragraph?

Please, could any of Victron's employee explain us step by step?

Option 1: use with 0 or 5V, (if I use a 3.3V signal, could RX pin of MPPT detect 3.3V as HIGH ?

Option 2: use by sending commands from arduino to MPTT.

Option 1 is simplest for me, that I must ensure that I am understading it well.

Thanks a lot.

Hi all,

As some of you know, Venus OS for raspberrypi is a hobby project by our developers, worked on in their free time.

And raspberrypi4 support has been wanted and asked for since a while now, as thats the now commonly available raspberrypi model.

We hoped and waited for someone in the community to step up and do the work, but that didn't happen. Perhaps too specialised a set of skills required (openembedded, linux, and-so-forth) - and I must admit that its quite the time investment to work on that.

Anyway, the good news is that we have a new set of images available. One image for the raspberrypi2 and 3, and another for the raspberrypi4.

So now, rather than looking to - or waiting for - the community to do the development work, we're hoping for people to do the testing work. Welcome to comment what work in your system and what does not.

Enjoy, Matthijs

Changes compared to our existing raspberrypi images:

1. Update linux from 4.9 to 4.19
2. The whole sdcard is now used and roughly 1/3 is assigned to /data
3. both root filesystems are also increased to roughly 1/3 each
4. u-boot settings are now stored redundantly on the sdcard; the FAT

   partition is no longer written to.

Not much has been tested, so the question is how many thing still work.

Note: these images are intended for that, testing, don't use them in anything serious. There are no automatic updates / bug fixes e.g.

This code is open source, and the changes are in this branch: https://github.com/victronenergy/meta-victronenergy/tree/WIP_rpi4

Downloads:

• raspberrypi2 and 3: http://updates.victronenergy.com/feeds/tmp/venus-image-raspberrypi2-20200517094246-v2.60~22.rootfs.wic.gz
• raspberrypi4: http://updates.victronenergy.com/feeds/tmp/venus-image-raspberrypi4-20200517094427-v2.60~22.rootfs.wic.gz

Note that they are full images. Its not possible to install it as a .swu file. They need to be burned to an sdcard, which erases all contents on that sdcard. For detailed instructions, see the Venus OS on raspberrypi instructions.

Things to test

Report results in the comments and answers below. Always include the exact model of RaspberryPi you are using please, and just to make sure there are no confusions, report firmware version & build number of Venus OS that you are using too.

Goodevening,

Have a 24/ 3000/ 70 here, which don,t respond on the dipswitch settings, so after making a setting the up and down button, don,t give any response.

If i look on the mother board front and backsite, looks horrible with all those mods.. ( first experimental victron ? )

I like to lower the output to 230.volt, after changing the burnt toroidal transformers the output is on the high site.

Also like to lower the charge output..

Any ideas welcome

Dear all

running on rpi version 2.54~1

unable to remove device 288 inverter

vrm is showing device 288 being my inverter but 288 Is already used by my bmv 700

290 is now my inverter

after removing all devices form the device list and disconnecting the usb cables, restaring the rpi even using. The Firmware 2.53
the 288 inverter is every time coming back in on the VRM website on the tab advance

how can this be solved?.

Hello all,

A new version is available for testing: v2.54~1. A maintenance release, meaning that its v2.53 (todays official release) + various fixes and small improvements that we found and implemented during v2.60 development.

This will be a short testing cycle, and once officially released we'll continue field testing of the v2.60 series again. Meanwhile, v2.60 beta files are not available for download.

In case you find any issues, welcome to post below. Thank you for your help!

Change log

• Add support for 24V Pylontech batteries. (by (a) recognising them, and (b) setting the charge voltage to 27.8V automatically).
• Fix bug in the Marine MFD App, aka Glass bridge integration. It worked in most cases, but since Venus OS v2.40 there was a configuration that broke it, and showed “Could not connect to the MQTT server” on the MFD: if the “VRM Two Way Communication” setting was enabled on a system not connected to internet. Now, also when there is no internet, enabling that setting does not cause any issues anymore.
• Fix a bug in relation to Fronius PV Inverters, that caused the system to read 0W output now and then, while the actual power was higher. This issue caused downward spikes in graphs on VRM, but could also affect the Fronius Zero feed-in functionality: all works better now.
• Include a few improvements that possibly fix the touch and/or display freezes issues with the Cerbo GX Touch display. We had a few reports, and went to some effort to reproduce the issue – but so far have not. So, we did change a few things that possible fix it, but not in a way that we are certain to solve it. Therefore: if you have the issue, then (if you can) please leave it as is, enable Remote Support, and put a comment or answer in below. We’re very keen to login to such system to diagnose further.
• Remove BYD Premium LV battery energy counters, there is a bug in its calculation which will be fixed by BYD soon.
• Kernel improvements for the GX card in the EasySolar-II GX, MultiPlus-II GX and the Maxi GX.
• Fix issue that (in quite rare cases) caused the maximum discharge current and voltage not to be communicated to the Multi. Thank you Wilco P. for reporting & helping to fix it.
• Fix bug that (in very specific circumstances) caused Assistants to not be updated with a new version when using Remote VEConfigure. This bug has been in in Venus OS quite a long time.
• Fix issue in combination with a recently released version of the VE.Bus ESS Assistant (version 176). In specific Assistant combinations it could cause DVCC status codes #3 and #4 to occur continuously. Thank you Mike L. for reporting.
• Fix bug in CAN-bus frames handling; which practically affect no systems at all but still needs fixing. The details: whilst for 29bit canbus only, the code also accepted 11 bit canbus frames, which in rare instances lead to ACL responses when using in a mixed environment (11 bit devices & 29bit on the same network). This bug has been in the code since all of Venus OS.
• Fix certain GPS-es not being recognised on the CANvu GX. Thank you Sturm Udrang for reporting this!

Best regards,

Matthijs Vader

how to automatically connect to two wifi connection?

- raspberry pi connect to my house is working perfectly but once on the road (motorhome) I use my iPhone to create a hotspot

The raspberrypi-Victron don’t connect

any tip on how to make that setting?

I built a 12V battery bank for my RV using Nissan Leaf Gen 2 packs. I am using the SmartShunt to monitor the battery. The Bluetooth signal is too weak to reach my phone when I am in the coach. Is it possible to run a communications cable between the shunt and Magnum inverter so I can read some of the status of the shunt there? As of this moment I have to lay in the basement bay to read the Bluetooth signal.

Thanks for your help.

I want to implement my own Battery Management System which should be connected over the CANBUS CAN-BMS protocol to the cerbo gx.

I found out so far that the BMS to need transmit the following CAN IDs to the cerbo gx.
0x351, 0x355, 0x356, 0x35A, 0x35B, 0x35E, 0x370

I have a flow that is set to open/close a relay on my 150/100 Charge Controller, however it is not changing the state of my relay. In the Victron App I have the relay setting set to "Relay Always Off". I'm not sure if the node-red flow takes precedence over the setting in the app.

The Node-Red flow successfully deploys, and I've put debug's in there to make sure it's properly sending a payload of 1 or 0 to the charge controller.

What am I missing? Why isn't it changing the state of the relay on the charge controller?

Hi.

I need help to make open source Grafana work on my Mac mini. https://github.com/victronenergy/venus-docker-grafana

The problem is that I struggle to install this correctly. Unfortunately I am not so good at command lines, so hope somebody could give me some tips to get this up and going?

I have cerbo-gx and this is connected with ve.can to nmea2000 cable and mqtt is activated so it should be correct. I have mac os catalina and installed Grafana and docker as described in the venus-docker-grafana project and so far I think this is ok.

-Step 2 with download of docker compose file I only get one page of text and here is my problem with command lines..

-The same goes for step 3, no idea how to place the file..

-Step 4 I do not get access to (http: // localhost: 8088 /) but docker is installed and works fine when I open the app.

-Step 5 and access to Grafane works fine.

Am I far off target or are there minor details missing? Very grateful if somebody can help solve this.

I have to grid tied PV inverters and one Multiplus II parallel to the grid in a three phase system.

One PV inverter is on L1 and the Multiplus is also on L1 (parallel). The other pv inverter is on L2.

As I can get and process the power of the grid tied inverters I would like to habe a possibility to get this information to the victron system. This would allow a better visualisation and the vrm portal would be able to show the correct consumption.

At the moment I have a Homeassistant system with all the data from the victron and from both pv inverters to store the data in an influxDB and show data like consumption in a Grafana instance. But I would prefer to have it all in the vrm portal.

I tried to set the pv input on L1 and L2 over MQTT but it seems like this is not possible as there is no write access.

Is there another way I could achieve this?

Best regards

Stefan

I would like to connect a Multiplus 12/800 (new one) to a Raspberry Pi Venus.

What cable would I require?

Will only an Interface MK3-USB work or can I use a VE.Direct to USB interface cable?

Also, would I be able to connect a Smarsolar MPPT to the same RPi, using a VE.Direct to USB interface cable?

Hello all,

A new test version available. See below for the changes.

In case you're new to the v2.60 beta test series, please make sure to read below six previous posts about them. There are several significant improvements in v2.60. The highlights are the addition of a feed-in limit, added ethernet-connected energy meters, updates on the NMEA2000-feature (addition of tanks), as well as many other improvements with regards to tank monitoring.

• v2.60~3 post & change log
• v2.60~4 post & change log
• v2.60~14 post & change log
• v2.60~15 post & change log
• v2.60~16 post & change log
• v2.60~19 post & change log

Change log

• Fix system setup AC input configuration being broken. Thank you @Eero Silfverberg for reporting. UPDATE: there are more issues with this, which we’ll address in the next update.
• Remove BYD Premium LV battery energy counters, there is a bug in its calculation which will be fixed by BYD soon.
• Fix starter voltage being shown for BMV-702 and BMV-712 while temperature or mid-point is selected as the aux function
• Disallow accidentally booting into an incompletely installed firmware update (this was -sometimes- possible by using the backup firmware menu. Not any more.)
• Improve the new grid feed-in limiter, by giving priority to PV Inverters over solar chargers.
• Improve the PV-limiting (aka zero feed-in) feature for large installations; sometimes they limited too much.
• Fix race condition that in rare cases caused the maximum discharge current and voltage not to be communicated to the Multi.

Note that there still is the same known issue: the new Ethernet-connected energy meters can't be configured; this will be fixed soon.

Other reported issues in v2.60 testing are still being- and/or will be looked into.

Best regards,

Matthijs Vader

Very interested in getting a Carlo Gavazi meter now they support Ethernet.. Couple questions for the community however, maybe @mvader (Victron Energy) in particular.. The Victron Release Notes specify (upcoming) compatibility with a specific model, "EM24DIN AV2 3X E1 X" - this is one of two models that use ethernet from what I can tell via their product page. My question is, will the AV5 model work, which uses Current Transformers allowing measurements over 65A? Specifically I am referring to model "EM24DIN AV5 3X E1 X"?

Second question, I see they now have wireless models, using "Wireless M-Bus", such as "EM24DIN AV5 3X W1 I X".. Will those units work too?

And last question, I saw in the known bugs, "the new Ethernet-connected energy meters can't be configured; this will be fixed soon." - does this mean they simply cannot be made to work yet until official release? Or what is the extent of this limitation?

I have a Venus GX and a Teltonika RUT955 router installed in my motorhome. The router has a separate GPS antenna and aware of the current location. I was wondering if there is any way to transfer this to the Venus GX device and then to the VRM portal?

The router has RS232 and RS485 ports, it also supports Modbus TCP. It is highly customisable so I was wondering if there is any way VGX can receive it? Which would be the easiest way?

I Have a Tracer 40A MPPT that uses Modbus protocol and am running Venus on a raspberry pi.

I've managed to run a dbus service as com.victronenergy.solarcharger.epever_ttyUSB2 and then in a separate script can publish values to it by writing on the system bus.

I can set the /State and the Pv / battery info fine and it displays in the "Device List" in the Venus remote console panel and the values update just fine.


I never get a solar item in the overview screen and it doesn't display on the VRM portal. Is there some values that I need to publish somewhere else other than the `com.victronenergy.solarcharger.epever_ttyUSB2` dbus item to get the solar input to display?

HI

I know the batrium bms is not officially supported but I have a strange display error on my new multiplus gx and its driving my OCD mad, and I am hoping someone with more knowledge then me can look at the gx code.

The current is being displayed with only 1 decimal point not 2 and the temperature is showing without a decimal place at all.

For example

the data sent on the can bus is "can0 356 [6] 0B 15 7C 04 98 03"

the voltage is correct and displays 53.87 on the remote console

The current is not and shows 114.8 instead of 11.48

The Temp is also wrong and shows 92 instead of 9.2

I believe this is possibly a bug in the gx firmware as even though the max charge current I have set is 60 it all works fine.

Thanks in advance

Hi, I am using the modbus register VEBus reset 62 which is 0=No action; 1=VE.Bus reset. However, the system reset regardless if the value is 0 or 1, meaning that it resets everytime I write 0 or 1.

Any solution?

Untitled document-1.pdfI currently have the battery disconnect connected to my battery with the battery + connected to the In connector and the out post connected to the TT main DC distribution block. The _ post of the battery is connected to a disconnect switch, and the BP gnd terminal. I have 3 questions,
1. Can the BP handle this if I connect to shore power and leave the Disconnect switch in the off Position? The TT has a charger/converter
2. When towing can I connect the batter With The disconnect switch on to allow emergency trailer braking? The battery is connected to the tow vehicles charging system I may have the solution hook up the tow vehicle charge cable to the in side of the B P
3. if I connect a pair of schotky blocking diodes across the BP to be forward biased when charging from the tow vehicle or built in converter chargers would this work?

Hello,

can somebody report back if it is possible to read/receive signals from an external RS232 interface? I do not need any further communication, no interaction, just receiving the data stream of a external RS232 interface (from my BMS). I can code/handle this all myself within the venus once I am able to retrieve any data.

I have looking the past few days and it seems all solutions handling the communication from a MPPT/BMV to a serial RS232 interface. I want the reverse handling, retrieve within the Venus GX a RS232 data stream.

Can I use the "usb to rs232" victron cable on the Venus GX? By now, I would do think using the VE.direct from Venus GX to the SR232 would not be working. My problem is that the BMS does only offer the GND/TX pin and nothing more. What about powering? I would think I would need a non-isolated cable?

Any feedback/input would be much appreciated. Thank you!

Bye Tobi

I’m new to the pi and Victron in general but I spent this evening getting my pi touch screen setup for touch, dimming and screen off settings. I got everthing calibrated and working, then on a whim I decided to see if there was a new beta build available and 2.30~40 was available. I installed it and it killed most of my settings (touch, dimming, screen off) and is no longer headless. However it kept some of my settings for dvcc, network and WiFi.

Is this normal behavior when upgrading the pi? Or maybe just with beta releases?

Thanks.

I Have a new install under Beta to check the 712BMV Smart. It still doesn't show energy in...

Hi All

Is it possible to change the gpio pins to pull to ground when switching relay on rather than 3.3v?

I've read that the rpi can do it but not sure if you change this in venus? I've had a nosey in gpio settings but nothing obvious jumps out at me?

Does anyone know where or how to change this?

I have managed to get 8 relays active with the switches in venus, but I bought a relay baord the ground switches not 3.3v hope that makes sense.

Thanks

Mark

All devices show up except the REC BMS

I am new to all things Raspberry Pi. I have managed to get the system running and view data from my solar setup in my van via a web browser but i am looking to install the Pi touchscreen in my van too. Is there anywhere to download the pre configured setup? TIA.

I've connected a GX Touch 50 to a Raspberry Pi via HDMI and USB. The screen works fine, however the Pi does not appear to detect the touch usb mouse.

Anyone tried this or have any ideas?
