I'm aware that Bluetooth is currently not supported in the Venus OS for Raspberry Pi. Is anyone currently working on this that I can share code/help with? Am wanting to pick up the data from a BlueSmart 24|16|1 in the Pi as I can't see that the Blue Smart has any cabled options (ve.Direct etc)

Hi, first, quiet hour should be more fleksibel called generator start profiles.

and i would like to have a digital input to change start input (activate quiet hour)

example.
Our hybrid generator is some times used for commissioning of wind turbine. We dont want soc be under 50%, so we have battery buffer for this heavy load task. (Load is higher than generator output in periodes.)

oposite, when machine is used at moderate peak periodes, we want to accept SOC down to 25%.

we would like to have a switch on the machine to chose profile after what work the system is supposed to solve at site.

A generator start profile could be a complete set of generator start settings, instead of only soc parameter. And the best was if self decide if need one, two, or more startprofiles for your installation.

and a easy override in gui to lock the machine for what ever generator start profile we want when workers are not allowed to self control operating mode with the switch.

For gui, more choices to choose what fuctions to present and operate on display/ consol

I'd like to reopen discussion on this topic. I'm a novice and freely admit that I really don't understand all aspects of how to get this to work. So I may be totally off with this so please correct me if I'm wrong. I've read this thread:

https://groups.google.com/forum/#!msg/victron-dev-venus/mejgJbMjU34/yogWAU5wCAAJ;context-place=forum/victron-dev-venus

I purchased the same board as what's here, the Expander Pi with the mcp3208 12-bit ADC.

From reading this, I'm a bit confused how to wire this up. In that thread, they point to the reference voltage of 1.8v. However the expander pi has a reference voltage of 4.096. But in other threads, they talk about a reference voltage of 5v. I also see the schematic of the BBB Cape and it says 5v as well:

[image]

I'm not sure what is correct or if the reference voltage even matters since both are 12-bit ADCs, the reference voltage shouldn't matter as it's just reading the resistance of the sender. But then I'm confused on how to wire this up with the Expander Pi. Anyone who has this board, would they care to share their setup, possibly with photos or diagrams? I'd appreciate it.

tagging @WKirby as you've always been super helpful!

Hi,

How can I connect a resistive tank sensor to venus OS on a Pi?

I own a camper and wanted to add proper battery monitoring. Your solution stands out bc of your support of the open source community. Thats why I bought a BMV-702 in a hear beat. Plus VE.Direct to USB to be able to get it connected with a Pi3B+ running Venus OS.

I want to get rid of the existing panel which only adds information about tank fill (fresh/grey water).

How can I add the tank information to venus os running on the Pi? Do I need some Can bus hardware?

Thanks in advance.

Hello! I am currently playing around with an off grid system for collecting victron data to display on grafana (with no internet). The system uses an influxdb server. At the moment it kind of works, but it is very hacky. It collects data via a cron job to query the dbus on the color control gx. Looking into mqtt now, and I was wondering if anyone wants to help out. I am not experienced in this field so it is a learning process for me. I want to end up with a guide for others to use that has the same or similar goals. Anyone interested?

hi, any plans for a better Venus administration than the remote consol?

what i would like to see is something similar as we find in IT products. (Switches and routers etc.)

and ehere we can easy save a configuration file and import it for next similar system rollout.

maybe a configuration tool for cloud system where you can roll out a configurstion to a number of similar systems Based one the one configuration file.

and.. why is the controller not in control of connected devices?

example... i want to reset soc to 100% on my bmv712, connected to Venus.

or adjust settings for when is fully charged on a running system....

also... when roll out configurations, a venus configuration file should be able to adopt and configure bmv devices, solar chargers and multi/quattroes In one configuration file..

based on the profile you have set.

the assistant should be only in Venus, no more fidling with each inverter, other than a guide to tell wich is master, slave . L1. L2 etc.

Yeah, i have a lot more but this is a start ... :-)

i am looking to create a Victron-raspberry pi...

First question

Does a raspberry pi communicate or display to the VRM portal

Does anyone has a list of hardware require for the Raspberry pi

Tks

Hi everyone

My motorhome has 2 x 140w solar panels, a Victron 100/20 regulator and 3 x 100 amp leisure batteries. I'm looking to run a 12v waeco compressor cool box from the load output terminals but want to ensure that the charge and condition of the batteries is always prioritised with the cooler box only operating when their is excess current from the solar panels. Could anyone suggest the settings I should use for the load output?

Thanks in advance.

Has anybody every customised the main page of their CCGX? From reading a few articles, it appears that it is possible (though people seem to customise the Venus GX). Any particular articles that walk through the steps/tips? I have a (Linux) software background, so it should be doable for me.

Specifically, most of the screen real estate is being wasted, as this ship does not have an inverter, and thus the top two thirds of the screen are always blank. Ideally I would like to:

• Expand the DC Power block to include a current figure.
• Add a block for the engine alternator, and show current flow from it.
• Display the AC current being fed from a generator.
• Display the AC current from shore power.

Is there any mechanism to display current/voltage data from external sources on the CCGX?

Thanks,

Allan.

Hi I'm running a raspberry pie as a gx for my charge controllers do I can view remotely I want to connect my batruim bms up does the hat for raspberry pie need to be shielded has any1 done this thanks matt

I was doing this;

https://github.com/SignalK/signalk-server-node/issues/517

And I messed up saving the files correctly.

The broken wifi access point doesn’t bother me, but I am wondering how to regain access to the vrm portal.

Here is what was mentioned;

vrm_auth_token.txt ...without it the system won't be able to send data to VRM anymore. Either make sure to keep that file, or after having booted the new version, go to the VRM Portal, Settings -> General. And scroll to the bottom. There will be an option to reset the token. This option is only visible afterthe portal has received data from the reflashed device.

Is there a way to recreate this file?

As an aside, signalk server running on a Venus GX did work..kind of.

Only the boats nmea2000 data that the Venus os could recognize was converted to signalk. The rest of the nmea2000 data was ignored.

I.e. tank levels and a bmv702 connected via ve.direct to nmea2000 was detected and converted to signalk, but no data from any other nmea2000 device was.

What is the best way to detect VE Direct devices?

Or do you mainly have to listen to every serial device at 19200 baud rate? I am currently creating an C++ application for Linux that will convert the all the VEDirect calls into one JSON device array.

I try to log data to my MQTT with a NodeMCU from my solarcontroller: "Victron SmartSolar MPPT 75/15". with this sketch:

https://github.com/physee/Victron.Arduino-ESP8266/blob/master/SerialRead.ino

I think i got communication running, but the output is as follow. Perhaps someone could give me a hint? (I am unable to contact the sketch-owner)

In a Cron job, the following two commands are not run:

00 12 * * * root /usr/bin/dbus -y com.victronenergy.settings /Settings/CGwacs/BatteryLife/State 9

00 16 * * * root /usr/bin/dbus -y com.victronenergy.settings /Settings/CGwacs/BatteryLife/State 1

I cannot see that the change took place looking on the Venus menus.

Hi!

I already did some modifications to OverviewMobile.qml to get values about storm warning that I populate from dbus from a python script that gets data from a json service.

I thought I have a basic understanding of how Victron Qt thing works, however, I am stuck getting a basic value from the service dbus the same way it works on my own custom namespace.

This is my code:

                 VBusItem {
                                id: localtimetogo
                                bind: Utils.path("com.victronenergy.system","/DC/Battery/TimeToGo")
                        }

If I want to display the value (localtimetogo.value), it always gives me undefined, when displaying text (localtimetogo.text) gives me "--"

What am I doing wrong?

thanks

Hi all,

According to KeepAlive paragraph in https://github.com/victronenergy/dbus-mqtt/blob/master/README.md I should run something like this:

while :; do mosquitto_pub  -m '' -t 'R/e0ff50a097c0/system/0/Serial'; sleep 5; done

in order to be able to maintain active subscriptions with the MQTT broker on Venus for clients on the local LAN.

The MQTT broker on Venus has this timeout functionality in order to prevent overloading VRM (fair enough). But ... would Ii not start to update VRM too frequently if I implement this keep alive function?

Instead of having to run a funny out-of-bounds script, would it not be better to be able to set a "keep alive" flag that the MQTT broker can check for use cases where local clients use the MQTT broker on Venus and would like to continue to be informed about changing data?

regards,
Jan

Hi All

I have a question about the Venus project on the raspberry pi

If you notice the unit shows “off” wondered why does it do that. Also I have a Victron Inverter, Charge Controller, and the BMV 712 connected using the ve to usb cables. They all display on the Venus interface but when the batteries are providing power to the inverter it does show the symbols for it.

It does show between the Venus and the inverter and from the CC to the batteries.

Also is there a way to make the AC go away. I don’t have a charger and under AC load 1 and 2 said disabled but it still shows. Just an annoyance but not a big deal

Am I missing something?

Hi, i need to add more panels to my boats solar system , i i am already using a 75/50 controller with a colour control and 12v/3000 multiplus, the controller is near to its limit, can i add another controller to the system , will it cause any conficts ?

Many thanks

Gordon

So I finally installed my pi and touch screen in my camper van. Everything is working fine on the victron product side but when I went to disconnect my tank sender from the manual gauge to install on the Expander PI ADC board and it still said shorted. I couldn't figure out what was wrong, then I take out the voltmeter and found that the tank sender is a 0 empty to 90 ohms full.... *facepalm*. I bought my camper van from someone else and the sender was already installed and I just assumed it was a standard NA 240-33ohm sender. Instead of getting a new tank sender, is it possible to change the settings somehow on the Pi to read this tank sender?

At least the panel turned out well (looks like I can't upload any photos).

Hi everybody !

I have VenusOS v2.22 which works perfectly on my RasPy and the newer version updated automaticaly few month ago when v2.23 was available (February) but i downgraded to v2.22 because some issues appeared...

I tried last week to check for the latest version (2.32) and the same issues encountered, i mean :

- AC Loads, sometimes display no value

- My Inverter is displayed "not connected"

In v2.22, i change only language in french (my language ;-)), and activate "has DC System" to log Inverter self-consumption, and it's all, no more configuration.

Why it not works in v2.32 ? Need some settings ?

Thanks you for help !

Hi!

I work for a research institute and we want to experiment with a small off-grid PV/battery system and a DC load.

I am looking for a charge controller which I can program easily to execute the experiments.
Is it possible to program a Victron charge controller to charge or discharge the battery according to variations from the PV power?

For example, if there is a fast drop in PV power, the battery starts discharging to the load. Or if there is a fast rise in PV power, the battery stops discharging and the PV panels start powering the load again.

Thank you for your time,
Ana

Hi all

This is post is both canvassing an idea / implementability and a reminder to post when I get around to doing it:

In addition to the numerical SOC, the idea is to add in a couple pieces of extra information (via node-red or some other mechanism):

1) The time at which the SOC was last reset ("Last reset was this morning")

2) A visual cue (say a traffic light) which gives an indication of the reliability of the SOC value. Last reset this morning = green. Last reset > 24 hours => yellow. etc. user adjustable of course.

I have read variations of this question here, but there seems to be conflicting answers.

I want to install a Multiplus right away but the battery bank I have ordered will be 6 weeks arriving in stock.

At the moment I have the AC in and two output circuits wired to a junction box ready to place on the Multiplus when it is fitted.

My question is: Will I be able to wire AC in and the two AC outs directly to the Multiplus instead of the junction box and have my house powered from the grid as it is now?

I think going forward this will be a very popular question: How to combine/integrate a Wallbox-Charger in/with an ESS System? What I'm not looking for are answers like: use the internal relay of a MultiPlus to turn on the charger when the ESS Battery is full.

It should be a smart integration in which the user can dynamically set the priorities, like:

1. charge the e-car using the remaining PV-power (ESS battery has 1. priority)
2. charge the e-car using all available PV-power (ESS battery has last priority)
3. charge the e-car as fast as possible

Options 1 and 2 would mean that the charging performance is constantly changing.

-----

Possible solution: use an external control unit which communicates with ESS and the Wallbox via Modbus. A control unit could be an OpenHAB system. I'm using such a system successfully for my smart home... A programmable Wallbox could be KEBA P30 x-Series.
The idea is to write a simple script which constantly reads some ESS figures, calculates the remaining power and sets charging power within the Wallbox. Option 1 could be realized quite easy, I guess. Any objections? Option 2 is more complex, but I think it could be solved as well. Option 3 is done without involving the ESS.

-----

Now, the big questions are: has anybody out there done this task already and can share the solution? if not, what other ideas do you have to solve the above challenge?

Many thanks in advance!

Hi all,

I'd like to retrieve the local time in a Python script running on Venus.

Venus is set to the correct timezone in the GUI ("New Zealand Standard Time") and shows the correct time too. The file system however does not reflect that; /etc/timezone contains "Universal".

Running "date" on the Venus command line shows UTC.

In Python there's also difference between UTC and local time:

Python 2.7.13 (default, Oct 16 2018, 12:48:19)
[GCC 7.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import datetime
>>> print datetime.datetime.utcnow()
2019-06-29 00:48:51.582668
>>> print datetime.datetime.now()
2019-06-29 00:48:57.102877
>>> import time
>>> print time.localtime()
time.struct_time(tm_year=2019, tm_mon=6, tm_mday=29, tm_hour=0, tm_min=49, tm_sec=59, tm_wday=5, tm_yday=180, tm_isdst=0)

Any suggestions?

Jan
