Venus OS v2.60~29 available for testing

Good day all,

A new version available for testing, v2.60~29. Several changes to the previous version - details below.

This post is intended for all people participating in the Venus OS Beta test program.

In case you're new to the v2.60 beta test series, please make sure to read the previous v2.60 posts, listed below. 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, and Solar chargers), as well as many other improvements with regards to tank monitoring.

I am, still ;o), aware that above list now amounts to a lot of reading and clicking back and forth: I've started on making it all in one, quite the list. And will share it here as soon as its finished.

What to test & how to report?

The updated Marine MFD HTML5 App need testing. Especially on different size MFDs & system configurations.

If you see issues, please post a new "answer" below; or in case the same issues is already mentioned, then comment on that to say you see it too; or help, and so forth. Please do mention the Venus OS version you have installed; just to prevent confusion.

Change log v2.60~29

  • Updated Marine MFD HTML5 App:
    • Allow access to the Remote Console while showing the "you need to enable MQTT" message; so that its also possible to immediately enable that. Much better.
    • Added a control element to start & stop a generator
    • Added a control element to monitor & control a connected Fisher Panda generator. More details on how to connect a Fisher Panda generator are here.
    • Improve scaling when using a large resolution
    • Note that we've found several other small layout improvements since this release - which will come in the next v2.60 beta version
  • Add transmitting custom names of tanks & temperature measurements to the VRM Portal - now they are visible in the Device list as well as the Advanced page
  • Fix an issue when using an older VictronConnect version to connect to Bluetooth on the Cerbo GX
  • Fix an issue related to kWh counters when using the AC Current Sensor and the related AC Current Sensor Assistant in the Multis and Quattros.
  • Small improvement when monitoring a tank level remotely and or through NMEA2000 (show Error when there is an Error, instead of showing OK when there is an Error).


Thats it for this version - all the best & have a good weekend,

VE Direct Extension Cable Connector Gender

Hi,

I am having trouble getting a VE Direct to USB cable work with a 5 meter VE extension cable I purchased. First I was surprised to find that the extension cable does not mate up with USB converter because it is male to male.

BMV-712 Female Connector --> Male VE Direct Extension to Male --- NOT OK---> Male USB VE direct converter

The extension is male to male while the USB is also male. I cannot find any Victron products that allow this. I now realize some people recommend a USB extension cable, but that is to late as this cable is already routed and sealed into the boat bulkheads.

I have attempted to make a gender changer and I am fairly confident I have the pin order correct. See pic as example. But my laptop does not see the BMV-712. It does see the FTDI device.

Is the cable just too long? Perhaps it doesn't like being run across a few feet of +12V battery cable? I don't really have any other choice.

I am hesitant to reverse order of the connector which would switch +5V and GND. Not sure if the devices can handle that if it's incorrect.

Victron Bluetooth BLE protocol?

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)

How do I reduce idle power consumption of MPPT 75/10 ?

The specs for the MPPT 75/10 say it dissipates about 250 mW. I have an ultra low power application and this is a significant waste of power, especially when the sun isn't shining. My system knows when the sun is shining, so it could control the 75/10. How can I turn off the 75/10 during low light so power isn't wasted ? Is there another model that does not use so much power ?

Venus OS v2.60~28 available for testing

Good day all,

A new version, v2.60~28, is available for testing now. Several changes compared to the previous version & coming closer and closer to the official release. The change log is below.

In case you're new to the v2.60 beta test series, please make sure to read the previous v2.60 posts, listed below. 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, and Solar chargers), as well as many other improvements with regards to tank monitoring.

I am of course aware that above list now amounts to a lot of reading and clicking back and forth: I'll soon work on combining it all in one complete v2.60 change log.

What to test & how to report?

  • The new feed-in limiter. If you see issues with it, welcome to post below. Also if it works well, very welcome to post your system details (what mppts, what pv inverters, etcetera) & that it is working well for you below.
  • PV Inverter monitoring & feed-in regulation. This was changed a while back in v2.60. No issues reported: all good so far.

The newly added Carlo Gavazzi EM24 ethernet energy meter is working well for a long time already (despite the currently missing config screen).

If you see issues, please post a new "answer" below; or in case the same issues is already mentioned, then comment on that to say you see it too; or help, and so forth. Please do mention the Venus OS version you have installed; just to prevent confusion.

Change log v2.60~28

  • Restore configuration pages for the new Ethernet meters (this was removed earlier in v2.60 test series).
  • Cerbo GX: disable the USB port close to the HDMI port. Now, it can only be used for powering the GX Touch. No longer for data such as a VE.Direct USB cable or a GPS. My apologies to those affected, and it is rather unfortunate that we have do this. I'm well aware this might catch some installations and users by surprise & we are not happy about it at all. But trust me, there was no other feasible solution. The datasheet has already been amended; and we'll be communication more regarding this change in the specifications. Meanwhile, if this affects your system, there is a simple work around to revert to the previous version using the Settings -> Firmware -> Backup firmware menu. Note though that using this port for data may lead to corrupted VRM data on USB sticks or unreliable communication to for example a Solar Charger when using a VE.Direct to USB cable.
  • Add read-out of raw resistance measurement for the tank inputs.
  • Show phase sequence issues for meters that support that (more details to be documented later; at the moment I don't know more details. Except that this is to quickly catch wrongly wired meters which can be very hard to determine from the other data)
  • Fix problem where position of PV-inverter on L2 of an EM24 or ET340 could not be set to Output. Thank you ?? for raising this.
  • GUI: Enable suppressing notifications with the center button again. This was broken earlier during v2.60 development.

Thats it for this version! I'll be going through all the various reported issues later this week.

Best regards, Matthijs Vader

Help wanted: testing new Raspberrypi 2,3 and also 4 images

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:


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.

BETA issue on Venus GX firmware

Hello, i am new to the Victron world, but experienced in IoT, Modbus, Control and energy management.

Yesterday my installer finished a nice ESS setup with 16x Pylontech batteries, Venus GX and 3x Multiplus 5000.

I had loaded the latest available beta on the Venus GX because my energy meter is far away and needs to talk Modbus/TCP, now:

- the Beta software seems to be broken in terms of communicating with the Batteries. The installer searched quite some time for the problem before finally downgrading the firmware and the communication with the battery started to work.

- the Modbus/TCP communication with the reader is very strange, it opens huge amount of TCP connections instead of opening ONE connection and using it. I do not have a Gavazzi with ethernet interface, but use the ET340 with a modbus/TCP gateway - so i can share the meter but also see much more. The sheer amount of connections opened is crazy, and the meter communication does not work.

Any ideas ?

I'll post system related questions separately

In particular;

- Maximum efficiency shows 95% (Manual 94%)

- Zero Loads power 11W (Manual 13W)

- Zero Loads in AES mode 7W (Manual 9W)

- Search Mode 2W (Manual 3W)

(I did not do an exhaustive check on all the data only the specifications I was interested in.)

Indications are that the Mulitplus II manual would be correct and the comparison pdf has errors.

If you could please correct the data inconsistencies would be appreciated.

Venus OS v2.60~26 available to be tested

Good afternoon Europeans & Africans, and night, morning, evening to the rest!

Just now we released Venus OS v2.60~26 to the Release-candidate feed, so it can be field-tested by all people participating in the Venus OS Beta test program.

Compared to the previous available version, ~25, this one contains a few changes, see details below.

In case you're new to the v2.60 beta test series, please make sure to read the previous v2.60 posts, listed below. 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, and now also Solar chargers), as well as many other improvements with regards to tank monitoring.


I am of course aware that above list now amounts to a lot of reading and clicking back and forth: I'll soon work on combining it all in one complete v2.60 change log.


What to test & how to report?

  • The feed-in limiter is definitively a new feature that will need testing (and possibly more improving) to make it good. If you see issues with it, welcome to post below. Also if it works well, very welcome to post your system details (what mppts, what pv inverters, etcetera) & that it is working well for you below.
  • PV Inverter monitoring & feed-in regulation. This was changed a while back in v2.60. No issues reported: all good so far.


The newly added Carlo Gavazzi EM24 ethernet energy meter is working well for a long time already (despite the currently missing config screen).



In case you see any issues, or in case for example you are using the feed-in limiter


Change log v2.60~26

  • Feed-in limiter (ie. the new feature as explained in the v2.60~14 post) is changed to improve feed-in limiting for systems having both AC- and DC-Coupled solar installed. Now, the DC-Coupled solar, ie the solar chargers, are limited first. Which is better, as for feed-in, AC-Coupled solar is more efficient, and also some PV Inverters are slow to ramp up once ramped down.
  • Add Solar Chargers to the NMEA2000-out function. Besides battery monitor data, inverter/charger data, and tank level data, the GX Device can now also make solar charger data available on an NMEA2000 network.
  • Fix GPS altitude being wrong for NMEA2000 GPS-es


Known issues

  • the new Ethernet-connected energy meters can't be configured; this will be fixed soon. They default to being a grid meter - so when used just for that, the missing configuration screen is no issue.


Best regards, Matthijs Vader

Cerbo GX - tank connect issues

I have a 2001 Safari Panther with the old tank sending units. They use resistance Ohm for what I believe is 4 levels. Empty, 1/4, 1/3/ 3/4 and full. I have hooked this up to the tank level block and having issues.

1. It has locked up the Cerbo GX tight. I am unable to move from the current screen. The only way out that I have found is to remove power completely and let it reboot.

2. If I select European setting, instead of USA settings, it does not lock up, but reads incorrectly. I jumped across the sensor to show a full reading, and it reads 4%. If I change it back to USA settings, it locks up again.

Any help greatly appreciated.

75/15 SmartSolar MPPT. Can I disable both solar and the battery with ONE SPST Switch turning off negatives to PV and BATTY?

75/15 MPPT: Using 1 switch EACH to A) Turn off solar before disconnecting battery (to prevent surge) and B) Disconnect battery to prevent 30mA SolrCtlr battery discharge.

Can I do both with 1 SPST switch to disconnect BOTH BattyNeg and SolarNeg? They appear to be connected per my ohmmeter.

I suspect I'm overthinking this and may not need the switch to prevent battery disconnect surge at this low amperage.

BTW, this is important to my RV customers -- 1 switch would make this MUCH SIMPLER! Thanks!

Is there a cheaper, more compact way of doing the job of an MK3? (Related to Pi Zero)

I know that there is interest in getting the Pi Zero working but nobody has cracked it yet. I was looking at hiring someone to tackle it but then Corona pressed pause on that.

I'm now slowly getting above water again and looking at it.

The use case here is clients who can only afford tiny solutions eg. 1200VA with a single 230Ah battery. This is wired into their house and allows them to run the basics without interruption - very valuable and they are very happy. But adding a Venus adds about 25% to the cost of this sort of solution. It is just too much.

Then, when the customer has issues, we cannot help them because we have no idea what was happening at the time.

A Raspberry Pi-based solution does not come in cheaply enough to justify the schlep compared to just supplying a Venus at cost. Board plus robust power plus SD plus MK3 plus time to build and load makes the Venus at cost a better solution for us.

BUT, if we could do something with a Pi Zero and an alternative to an MK3, we could provide a very simple solution with probably enough power to manage just a single device eg. a MultiPlus.

I understand that Ve.Bus is not Ethernet but just uses the RJ45 connector. If that is the case, could the RJ45 not connect directly to the GPIO of the Pi and we implement the protocol on the Pi?

I may be talking total crap, in which case, set me straight and I will carry on living my life.

But, if I'm onto something here, we could build something very small and simple that could help a lot of installers out there better serve their clients.

Bug report: VRM consumption calculations are incorrect when using non-victron charge sources

Hello,

I noticed that consumption in VRM "System overview" dashboard graphs and widgets are always way smaller than they should be. I think I got to the cause of it, hence this report and ask for a fix.

Below in red rectangle you can see how it has been for months - consumption always shown lower than it was. Then I started playing with the settings and got it to show up more or less right - in green rectangle you can see how the consumption is in reality.

[image]

As you can see in "Jun 18", discrepancy is about two times! So what's the reason?

There are various DC chargers in this system, of which mainly two of them generate the bulk of energy:

  1. Non-Victron solar charger 80A
  2. Victron solar charger 85A

In order to see all the chargers conveniently in the "Remote Console", I have had "Has DC System" enabled. Then I see all chargers summed up in "DC Power" box. If the value is negative there, it means "DC System" is charging and all is great! At least you would think so.

[image]

However, what you can see in the picture above, is that VRM on the left shows very tiny consumption (224 W) compared to the real one (1395 W AC). There is some time lag between these two screens, but I noticed that essentially VRM takes AC consumption and adds DC Power. So, if you have any external chargers (like non-Victron solar, wind or even a generator with DC charger), "DC Power" shows as negative and VRM just blindly deducts that charging power from the consumption.

As soon as I turn off "Has DC System", the consumption shows up more or less correctly:

[image]

This is very inconvenient, because if you have any non-Victron charger and disable "Has DC System" in favour of correct VRM consumption, you can't see it in Remote Console view.

What's the possible real fix? VRM should only add "DC Power" to the consumption if it is positive, but ignore the value if it is negative (in other words, when DC system is charging as opposed to consuming).

Would someone from Victron step up to address this? As it stands right now, the system is not capable to deal with heterogeneous setup :-(

Finally, one more related bug in VRM's "Consumption" dashboard even with the disabled "Has DC System":

[image]

Here you can see that half of the energy is said to be used "from battery", which is just wrong. All that blue energy was generated by the mentioned non-Victron charger. What's worrying here, is that this system has a BMV which knows exactly how much went out of the battery (and in this case it was 0.0Ah), but VRM is using some kind of convoluted formula to get these numbers as opposed to using data from BMV.

It would be really great if this use case with not only Victron chargers be addressed, because as it stands right now, the whole VRM Dashboard tab is just disinformation.

Thank you in advance!
