Cerbo GX bluetooth connection lost.

Hi all,

I accidentally hit "forget this device" for the bluetooth connection to my Cerbo GX and from that point i am not able to find Cerbo GX in my bluetooth list on an iphone running the latest OS version.

I tried restarting both Cerbo and the iphone with no luck. I also tried to change the Cerbo GX name but again this failed although i am able to connect to it using bleutooth using another phone or any other bleutooth device (i.e. my laptop).

It seems that resetting my network settings on the iphone will fix this issue but it will also delete all my wi-fi settings which i want to avoid.

Anyone had this issue before?

Thank you in advance.

cerbo GX battery percentage false reading

Hi, I have a client with a 12v 3kva multiplus unit connected to a cerbo gx screen with a smart shunt. He has sent me a video of the battery percentage readout on the cerbo gx screen which while charging, it jumps from its actual percentage (74%) down to 1% and back constantly. It only does this while charging and it is mimicked on the VE connect app via bluetooth. Any thought as to what could be causing it?

Welke parameters instellen bij laden met aggregaat

Ik heb een offgrid systeem in Spanje, dus zonder AC aansluiting, bestaande uit 24 x TZS 12 accu’s (2335 Ah / C120 / 1.85 V) en 2 x 12 zonnepanelen met 2 x Xantrex Charge Controllers en nu sinds kort, omdat de Xantrex inverter kapot ging, een Victron Quattro 48V / 8000 inverter met Cerbo GX Touch. Accu’s worden geladen door de zonnepanelen en indien te weinig stroom wordt middels een aggregaat (3-fase) via een Flexi Plus 48V 100A snellader de accu’s bijgeladen. De Victron wordt nu dus alleen als inverter gebruikt, gekoppeld aan het accupack en zet DC om naar AC.

Ik laat de Cerbo GX via Relay 1 automatisch de aggregaat starten. Mijn vraag is nu welke instellingen ik het beste voor bovengenoemde situatie in de Cerbo GX kan instellen. Dus, wanneer moet ik de aggregaat laten starten en weer stoppen ?

Cerbo GX denying WiFi/Bluetooth and Remote Console, i tried all i could find here in the Forum, what else might help?

Hey People,

i got my Cerbo like 2 Weeks ago and almost everything worked fine in the very beginning. But only for a very short time. When i first connctec via BT via Victron Connect App it worked, same with WiFi. But after Firmware Update 2.63 it stoped both connecting with WiFi and Bluetooth. I also discovered that i don't have access to Remote Console. I rebooted, i reinstalled older Firmware, i disconnected the Cerbo Touch Display, i moved it a bit more far away of al the other Victron Parts. Nothing helped.

But one thing is interesting. I already connected with 4 different WiFi Networks and all of them worked for a very short period. Yesterday i had an idea and tried to connect to my neighbors Network and it worked for a few minutes, but unfortunately then lost connection ever since. No reconnection possible.

The Cerbo is showing correctly all Networks and it seams the new networks might work in the very beginning.

Another thing i discovered, once i tried connecting the Cerbo with its own Network, the Venus HQXXX... it did. After that i had very short connection with my main WiFi Network again - but now even the Venus HQ Network doesn't connect any more. Saying Failure/Disconnected.

Now i´m really out of ideas what might help. Hopefully i described everything in the best way so you could understand what my issue is. Thanks for help. Cheers, Marcel

Confused about local LAN and Cerbo GX

I’m trying to connect to the Cerbo GX remote console and aware that you must use either a LAN connection or VRM.

my confusion lies with the definition of LAN. The Cerbo has a built in WiFi access point that I can connect to via my phone using the QR code. Should I be able to connect to the remote console after connecting to the Cerbos access point? Or does my Cerbo need to join a network (ie: my home network) in order for me to connect to the remote console?

Skylla IP65 controlled by CAN-Bus via Cerbo GX configuration problem

Hi Community,

I have two Skylla IP65 paralleled and connected to a Cerbo GX via VE.Can and one "other" BMS for a LiFePo4 battery, also connected via BMS.Can with 500kBit/s or via the same Ve.Can bus with 250 kBit/s. Works both.

The Cerbo GX shows all three devices. Also the Cerbo shows values from the BMS for Charge Voltage Limit (CVL), Charge Current Limit (CCL) and Discharge Current Limit (DCL). I can see all three values in my BMS configuration tool also. Thumbs up!


Both Skylla IP65 don't react! I tried:

- Connecting only one Skylla
- Setting Parameter #31 BMS to "Yes" - which results in an error #67 "BMS communication lost"
- Switching DVCC on and playing with some parameters

No matter what I do - the Skylla chargers do what they want instead what the BMS wants...

Does anyone have a similar configuration up and running, especially with a Skylla charger?

Should I upgrade to SmartSolar MPPT? (corrected)

Hello, I have an Airstream with BlueSolar MPPT + MPPT Control. If I add the Cerbo GX (which replaces the mppt controller) + a Smart Shunt, is there any benefit to upgrading from BlueSolar to SmartSolar if all devices are connected to the Cerbo via VE.Direct cables?

In other words can the smart shunt & blue solar share info via the cerbo or do they still need the ve smart network over bluetooth to share info?

Feature Request Cerbo GX/Venus GX: Combo Load Shunts for Power Monitoring

I've seen other monitoring systems that have 4-in-1 shunts to measure loads or voltage sources. Does Victron have plans for that? I'm very much sold on the Victron ecosystem, but this seems to be a feature "hole." It would be great if we could see how much power our A/C, refrigerator, lighting, etc. are consuming, or how solar strings compare to each other in generation, etc.

Thanks for making awesome products!

Unable to connect to Cerbo GX from Raymarine Axiom using the Victron App

When I try to connect to the Cerbo GX using the Victron app on the Raymarine Axiom MFD I get a connection error "no hardware found" and the application does not start.

The Cerbo GX is connected to the NMEA2000 network using a Victron VE.Can to NMEA2000 cable and the Raymarine Axiom MFD is connected to the same NMEA2000 network. The NMEA2000 network works fine and is properly terminated. Since the Axiom is connected to an Quantum 2 rader with cable the Axiom must connect to the Cerbo GX through the NMEA2000 network.

The NMEA network diagnostic screen on the Axion shows not only the Cerbo GX. But also all the devices connected to the Cerbo GX with VE.CAN, VE.Bus or VE.Direct. Attached is the NMEA2000 network diagnostics from the Axiom listing all the NMEA2000 devices as well as the Victron devices that the Axiom can find on the NMEA2000 network.

- The Raymarine Axiom is running the latest lighthouse operating system (v3.13.103 Edgartown)

- The NMEA2000 network is powered separately and the fuse in the VE.Can to NMEA2000 cable is removed

- The Raymarine Axiom can see the Cerbo GX on the NMEA2000 network (and all devices connected to the Cerbo GX, including tanks)

- The Cerbo GX and all connected Victron devices are all running the latest firmware

- All data from the Cerbo GX are visible on the NMEA2000 netowork and can be displayed in other ways such as webguages with yachtdevices wifi gateway

- On the Cerbo GX: one VE.Can port has a VE.Can terminator and the other VE.Can port is connected to the NMEA2000 network using the VE.Can to NMEA2000 cable

- The NMEA2000 network is a Raymarine SeaTalkNG network

- The VE.Can to NMEA2000 cable is connected to a SeaTalkNG<->NMEA2000 cable that is connected to a "white" device port on a Raymarine 5-way

Cerbo VE.Can port settings:
- CAN-bus profile: VE.Can & Lynx Ion BMS 250 kbit/s,
- NMEA2000-out: Enabled

Starter battery voltage monitoring with isolated systems

Hi there,

I currently use the aux input on my BMV-712 and the Cerbo GX/VRM to monitor the start battery voltage in my boat. Being an aluminium boat I am making a few changes to the system to ensure that electrical systems are isolated from the hulls and that the start battery system is fully isolated from the house battery system. This means that the aux input on the shunt won't be able to read the start battery voltage any more, as they won't have a common ground.

What other ways can I get the start battery voltage into the cerbo GX and VRM for monitoring purposes?

A little more detail on the system if it helps:

- 2 x 25.6V 200AH Smart Lithium

- BMV-712

- Multiplus 5k

- 4 x MPPT 100/20

- Cerbo GX

- Orion 24/12-70 for running 12V house loads

- Swapping the Orion 12/24-20 for a Orion TR Smart Isolated 12/24-15 for charging the house from the start batteries

If only the Orion TR Smart could do communications over BT or VEDirect this would be easy.

Can cerbo GX connect to auxiliary digital inputs

I'd like to use the Cerbo GX for monitoring, amongst others, the bilge alarms. But as we have 6 bilge alarm switches already the 4 inputs of the Cerbo is not enough. Is there a way to connect a standard (like modbus or NMEA/CAN) external module with more inputs that the Cerbo can use?

Or is there an extension like the GX tan 140 but for inputs (planned)

Cerbo firmware 2.65 update won’t install

I tried to update my Cerbo firmware from 2.60 to 2.65 via the usual VRM procedure. However it seemed to get stuck on "updating ..." and nothing got updated.

Also something did happen as I have lost the previous OS version in the "Stored Backup Version" tab. Whereas before that gave me the option of reverting to 2.58 or sticking with 2.60, now it just says "backup firmware not available".

I download the enstien .swu file from Victron Professional and copied to an SD Card and tried that way and while the cerbo recognises there is a firmware file on the card it will not do anything with it.

Before I tried the 2.65 VRM style update on the Cerbo, I checked it on the RPi I have and that installed fine in the usual way and in the "Stored backup Version" tab I have 2.65 running and 2.57 as a backup, so that is all normal.

What do I need to do to get the Cerbo updated? it seems it will be stuck on 2.60 forever! and losing the ability to revert is a bit worrying as well.

Cerbo GX wifi issues

I have had my Cerbo GX with touchscreen installed in my motorhome for a couple months now. Most of the time it won't stay connected to my WiFi, which is about 8 ft above it. I use a Pepwave Max Transit Duo WiFi modem, so it's a pretty strong unit and the Cerbo shows around 75-80% signal strength. I can force it to connect, and sometimes it stays connected, sometimes it doesn't. Even when it's connected, I can't connect to the remote console much of the time. I'm on Firmware 2.57. Any suggestions?

Solution to Cerbo GX Wi-Fi issue when having the GX Touch connected

Dear all,

This message is to inform about a Wi-Fi related problem in the Cerbo GX. Some Cerbo GX-es will not properly work on certain Wi-Fi networks when having a GX Touch display installed. If they do or not depends on the (channel of the) Wi-Fi network, and on how exactly an antenna cable inside the Cerbo GX ended up when manufactured.

Its obviously not good and I’m not happy with it, but it is what it is and you’re better off knowing all the details than not knowing them.

There are a few solutions, one is to simply send it back to your dealer; to have it repaired.

The other is to make the wifi network work on a one of a few specific channels; which don’t have the issue (details in the pdf)

And lastly, if you’re technical, you can fix it by opening the unit up and repositioning the antennas to make sure its cable is no longer close (or even touching) the hdmi connector or surrounding area.

Now, don’t get me wrong wrt the repair: you’re more than welcome to return it for repair. But still I chose to share the details of the repair as I can imagine that for some it will be the preferred option.

Lastly, my apologies! Especially to those who have spent a lot of time trying to find out why it wouldn’t connect to wifi.

And a big thank you to @WKirby who helped uncover the issue and even to find the solution. Warwick has been a great help in this.

All the best,

Matthijs Vader

Ps. All distributors and dealers have been informed about the issue via email.
