Is there a way to connect my Venus GX to my PRTG using MIB? Or any other way?
After upgrading the firmware of my Venus GX to version 2.72 I am having issues with it not continuously publishing to the mqtt broker.
When I connect a client to the broker in the GX I receive the subscribed messages for about a minute after which an empty message is received and no more messages are received until about 1 minute or 2 later. This just keeps on repeating.
I suspect there is a timeout issue or it somehow does not get the keep-alive messages.
I was unable to find a change-log for 2.70 to 2.72.
I would also rather not roll back but I also cant seem to find a way to even roll back the firmware.
After creating a profesional account I am able to access the changelog. Though that did not really explain why mqtt is misbehaving in 2.72.
It did however point out how to roll back so I rolled back to 2.66 which resolved the mqtt issues.
However that may cause me to be unable to configure my EM24 ethernet as that was not yet added in 2.66.
I am not sure i understand, if i set the grid set point to 50W then i set the Energy Meter to external what happens then ? If i set the grid set point using dBus or MQTT then i need to make the phase calculation myself as described in the ESS manual ? Is that what ESS does when it has energy meter itself, it sets the grid setpoint dynamically based on the loads on the phases that it's told or am i misunderstanding ?
I am looking to gather the data in my Home Assistant Dashboard for the Orion-TR smart 12-12 30AD c-DC I know that the data is fed with the Bluetooth but Victron don't give us the possibility to connect to I was thinking adding an additional Shut at the output of the DC-DC with the Ve-cable
- It this feasible?
- Will it disturb the overall electrical system?
- If yes, will the additional shut be displayed on the RaspberryPI 7 inch screen?
- If yes, will it be possible the get the information via the MQQT mapping
Curious what kind of performance others are seeing on their CCGX from an MQTT perspective. I have been having issues where data wouldn't update for 10 or more minutes. I'm utilizing node red as a client and have all QOS set to 0. I've switch from wifi to ethernet on the CCGX and disabled all non essential flows in NODERED. Likewise I have disabled VRM and remote access to attempt to reduce all overhead possible on the CCGX. However, I am still seeing sluggish performance. It does seem as if I was able to improve things a bit but wanted to see if anyone else had any suggestions.
How can I via mqtt determine if Im charging or discharging my batteries.
My Cerbo GX is on Firmware V2.60, which I understand is the latest as at mid December 2020. I also understand some networking/password issues with this Firmware edition are being investigated.
Connectivity of the Cerbo to a B&G Zeus3S is very flaky. MQTT is enabled. Upon startup of the Zeus3S, the Cerbo’s Remote Console will be visible on the Zeus for a couple of seconds or for a few minutes, but the following error screen always appears. Can anyone deal?
My boatbuilder’s electrician and Victron installer is stumped wrt this problem. The one other Cerbo he installed, with a Zeus 16” glass cockpit multifunction device, did not have this problem. Older Firmware, perhaps?
Edit - prompted by JohnC’s answer: My B&G Zeus3S multifunction device is the 12” version.
Edit: the screen resolution for the B&G Zeus3S is 1280x800.
Edit: the ethernet cable connection between the Cerbo GX and the B&G Zeus3S is composed of a standard UTP ethernet cable from the Cerbo, to a B&G NEP-2 Network Expansion Port ethernet switch box, then a B&G cable with a five-pin connecter to the Zeus 3S chartplotter. Should work - and does work, in terms of making the link and communicating via the MQTT protocol. It’s just the weirdo crash and error message that’s the problem. I can find nothing in the Zeus for dealing with screen size or resolution, other than a text size selection, which did not help. I understand that Victron is not in a position to assist with networking problems via this forum. Fair enough. This is looking like something other than a network problem.
When trying to connect to a site with VictronConnect, I get the following error:
"MQTT-RPC unable to retrieve the list of devices, the attempt timed out."
is it possible to get the "total yield sent to the grid" via API / MQTT ?
There is a nice graph showing the "sent to grid" values (in red):
But can I get this value using API or MQTT ?
I am able to read the total pv yield from my MPPTs, but thats not as interesting as the value that was sent to the grid for me.
Hi, i accidentially read that my VenusGX seems to send my data via MQTT to this public Victron MQTT Broker. Is that true?
Can i stop this somehow - but still keep the local broker running (as i need this one). I checked the settings on the latest firmware version, but i only see MQTT with and without security...but no information on this external broker.
Any idea how to disable thisf?
Hi, I have a EasySolar II GX 250/70 - 3000. I am reading the MQTT successfully for other display purposes of performance of an EES setup. Right - bottom on this is "PV Charger" with watts.
the closest topic I could find to read that is /solarcharger/273/Yield/Power, but it reads about ~33W higher. than what is shown on the screen of the CCGX remote console. Anybody got an idea of the right topic for that value?
my solar charger doesnt report the equalization state properly. I have lead-acid battery and I have set up the MPPT to perform regular equalization. So far it is working fine. When I check the MPPT physically it states the equalization phase on the LCD but when I check the MQTT output on the Venus GX (or VRM portal), it always show the state with value 4, i.e. Absorption. Any idea why is this happening?
I have 2 MPPTs (BlueSolar 150/70, firmware 2.05) in paralel (working) connected with VE.Can to Venus GX (firmware 2.53). There is also the Quattro and BMV-700 connected to Venus. For the solar charger state I use the "/State" dbus-obj-path. When equalizing by the Qauttro, the Quttro's state is correct.
I have turned on MQTT on my CCGX and I am able to subscribe and get messages. I want to be able to change the generator start/stop rules which are based on the Battery state of charge. They are current at 50% and 70% but I want to be changing them programmatically depending on forecasts. Does anyone know the topic to publish to so these values could be changed?
Since Sunday 21:12 AEDT (Melbourne, Australia), I am no longer receiving new data from mqtt.victronenergy.com. The connection seems good, my CCGX is healthy and VRM portal continues to be updated.
When I restart my mqtt client here, it does receive from the server all the "retained" data, but no new data flows.
Is there a way to connect my Venus GX to my PRTG using MIB? Or any other way?
I can see via Remote console where to selected mqtt under settings/services, I know the IP of my VenusGX, is there a username/password to select/use,
what's the QoS, and lastly whats the next option suddenly shown "NMEA2000" ?
In a setup that consists of :
1 X 5kva Muiltiplus
2 X SmartSolar 150/70
1 X BMV 702
1 X Venus GX
1. Can the two SmartSolar charge controllers operate in true parallel (ie both be in the same state)?
2. Can the charging be temperature compensated using the temperature sensor attached to the Multiplus? If not, what do I need to buy to do this?
3. Can the GX publish MQTT topics to my own MQTT broker (Mosquito on another RaspPI)?
4. Can the BMV 702 talk to the GX using a BlueTooth dongle?
Thanks for your help
I originally posted this on the victron-dev-venus Google group, but wanted to move it over to here as this may be a more appropriate place for it now. Here's a link to the original post:
Basically, I have a REDARC BCDC1240D DC-DC charger that I use to take power from the truck alternator and charge the LiFePO4 batteries in the trailer. If you're interested in reading more, I wrote it up here:
It all works well, except because the DC-DC charger isn't Victron (and Victron don't have a suitable product), it doesn't talk to the Victron system - i.e. the CCGX. This means that all the CCGX displays is a net DC figure - but I have no way of breaking that down into how much energy is coming in from the charger (e.g. PV) vs how many energy is being consumed by DC loads in the RV.
In fact, from a data perspective, the device is dumb - there's no way data / comms available from it at all. My plan is to build a small MCU-based device with an INA3221 (essentially three INA219 chips combined) to measure the current and voltage on the 3 legs of the charger - PV input, alternator input, charger output.
My question is about the best way to get this data into the Victron system. My thinking was simply to write on the relevant MQQT topics so the charger shows up as a new device. Will that work? Has anyone done this before, and specifically, Victron doesn't have an appropriate device type for a DC-DC charger so I'll have to create some topics of my own.
in the next days I am going to setup Node Red with MQTT and my ESS.
The first tests are successful. But I only want to use it on local network for a display showing live data.
As I know, as soon, as I use MQTT in the venus gx, the data is also sent to mqtt.victronenetgy.com.
I see this in a light upload traffic. Well, I do not really need the online feature. So is it possible to disable it, while keeping the local function?
Can you make a switch in config menu?
