VictronConnect can't see any devices on Local

I've drastically shortened my original post, as I had no replies.

I have a Cerbo GX which is connected on my LAN with a BMV-700 Battery Monitor and a MPPT 100/50 Solar charger

My desktop PC can see the Cerbo in it's list of Network devices.

I can Ping the Cerbo, and can connect to the Cerbo GX by clicking on the network icon. or by entering "venus.local" in the browser.

I have VictronConnect running, and can access the Cerbo via the VRM online portal, However under "Local", VictronConnect says "No Devices found".

I need VictronConnect to talk to the Cerbo directly as I normally have no internet at this site.

Can anybody help please?


Thanks ..... Zim

VC local with a LAN only connection is rather pointless, does the app work when you select the VRM tab?

Local with LAN only should see the GX but it will just redirect you to the remote console page.

It is meant for using bluetooth (when in close proximity to the devices) or the USB VE adapters.

There are also some limitations like Windows blueteeth is (or wasn't) supported.

If you are using wifi anywhere in the chain, some access points use their version of islanding to stop clients talking to one another locally (for security).

Desktop firewalls/endpoint protection can also block some comms.

Thanks very much for your help.

My understanding is that VRM requires support from the Internet.

I just did a quick test, and with the Internet unplugged, the VRM is dead

(although I can still access the web page in the Cerbo).

But to access the more technical settings, I need the Gear icon in VictronConnect, which apparently I can't use over the LAN without an internet connection.

If this is correct, it makes the LAN connection (and Cerbo RX) useless for me.

Yes, vrm requires internet access.

The remote (lan) console allows you access to cerbo/venus configuration- shared configuration like dvcc and ess, among others.

If you want to access advanced settings of the mppt/multi you will need both a mk3 usb cable (for the ve bus devices) and bluetooth for the rest. Bearing in mind windows does not support Bluetooth config.

So if I were to set up a boat or an RV with various Victron boxes scattered around, it would be pointless to connect them together with a Cerbo RX and LAN.

If I wanted to access any advanced settings, I would have to go around with a laptop, unplug each VE.Direct cable (or whatever) and plug in WiFi or Blue Tooth adapters at each device whenever the Internet was unavailable.

Surely this cannot be true.

The Cerbo/GX provides shared services that helps all the devices work together, so is required for most setups.

It also provides a neat dashboard of what is going on which can be displayed on your phone, or an external display.

This can be accessed also by the internal wifi AP on the device so a LAN cable isn't specifically required.

Generally, once configured, you shouldn't need to go around connecting to devices though you can now get some good trend (beta feature) data off mppt's etc.

Victron don't have one management tool that is platform independent.

If you want to configure/update a multi properly, victron connect only allows a basic subset of settings. You still need a windows laptop with a mk3 USB adapter and veconfigure to set the inverter up properly. The rest (shunts, mppt's etc) have less to setup and can be configured and upgraded via VC.

This will no doubt change with time.

Thanks again for your help.

Firstly I did solve my problem with VictronConnect not seeing the LAN devices on Local. After much experimenting I swapped my Ethernet hub for another and it started working. Strange that all other network functions worked, except for VictronConnect's local traffic.

I also see what you mean about VictronConnect handing local connections over to the Remote Console web page on each device. This is very disappointing.

Oh well, it's been a painful learning experience. I do hope that Victron can fix some of these glaring gaps in the near future.

As you can probably see from some of the questions on this community forum, there are a lot of DIY'ers buying stuff and thinking it is just all plug and play, or working on how they think it should work.

Victron is a great product which is very flexible and feature rich.

To avoid problems you really need to know how the ecosystem fits together, it just takes more than connecting a bunch of wires together.

It is actually very well documented, but too many people over-estimated their abilities and then the product takes an (unfair) beating.

Sure there are some quirks but that applies to everyone.

Properly designed and configured, you won't be disappointed.

There are 4 ways to access the Cerbo. Locally you use the qr code. Or logon to its own local wifi access point or bluetooth. It does not need internet.

You absolutely do need the internet if you want to access the advanced settings of devices attached to the Cerbo using VictronConnect via the LAN.

With my system, I happened upon a way to connect locally to my Cebo GX without my having an internet connection.

Background 1st:

For a while, I could open Victron Connect and it would find my Cerbo GX as a 'Local' device. Then it disappeared. Now whenever I try with VC, the only way I can access my Cerbo GX is with VRM, which requires an internet connection.

Sometimes, if I unplug my Ethernet router connection to the Cerbo GX, and plug it back in, I can then go to another Ethernet-router computer on my network and VC will show me my Cerbo GX in 'Local.' But then, a few minutes later, if I close VC and re-open it, my Cerbo GX has disappeared in 'Local.'

But a different solution appeared:

I go directly into my router's DHCP table and it shows my Cerbo GX IP address. The name is 'einstein.' Then in a separate browser window, I simply put in that IP address and I'm instantly in the Cerbo GX Menu/Pages section. I can change the available settings, look at current production, etc etc. I just don't have the pretty 'Dashboard' that VC usually starts with.

For instance:

My 'einstein' is 192.168.1.15

In my browser URL space, I type in 192.168.1.15 and the browser puts in the http:// and instantly I'm in.

I don't have WiFi - only Ethernet - but I think this "Enter the IP Address" method should work with WiFi also, as long as you are entering the IP address correctly in your browser.

Will this work for you too?
