Victron has great visibility with their GX series of products, but there's an open source product that makes it even better. And recently Victron have updated their systems so you can get push alerts.
GuiMods
The standard GX display screens are great and provide a quick way to see where power is flowing, general battery status, and more. However, it doesn't show a ton of detail, and if you want to change specific settings, it requires a number of clicks.
GuiMods provides even more details in one screen as you can see above. Some of the things that have been added that I leverage:
- Voltage / frequency / amperage at both the source side (Shore) and the inverter output side.
- Shore amperage limit setting
- Watts and amps on the DC side
- Charge / discharge / capacity bars for each box
Installing
Keep in mind that this process requires a moderate amount of technical ability to install the various bits required.
To install GuiMods, you will need to install SetupHelper first. I've used the "blind install" and done a command line install as well. Both work fine, although the command line version I found to be easier than moving SD cards around.
Once you have SetupHelper installed, you're ready for GuiMods. Here are snippets from their installation notes (at the bottom of the readme on the page above):
The easiest way to install GuiMods is to do a "blind install" of SetupHelper and then add the GuiMods package via the PackageManager menus.
Once SetupHelper is installed, you can add GuiMods by placing the archive from its GitHub repo on a USB stick or SD card and inserting it in the GX device (CCGX, Cerbo, etc.). PackageManager will detect the archive and transfer the package to local storage. It will then appear in the Active packages list.
Once you have installed GuiMods, you usually won't ever have to do this again - upgrades and updates are much easier.
To confirm you'll get updates automatically, head into Settings and scroll to the bottom and choose Package manager.
I enabled (if I remember correctly) Automatic GitHub downloads that keeps the latest version downloaded. If you click into Active packages you can see more detail.
The "Auto install packages" from the previous screen, I believe, keeps the latest version that is downloaded installed. The whole PackageManager setup is a bit unclear at some points, but I understand the need for it since Victron have not really provided a 3rd party installation management system. You may have to experiment a bit with the settings in here if you don't want automatic updates.
Configuration
There are a lot of settings you can tweak with GuiMods, which can be a bit overwhelming. I've also seen them change a lot as the developer works through changes and feedback.
To get started, head into Settings -> Display & Language -> Gui Mods
I would highly recommend reading the entire page at GuiMods and writing down specific things that interest you before jumping in too deep. There are so many options and settings, that you might want to try changing a few things at a time to see how things look.
Various settings in GuiMods
I played around with a lot of them to get things looking the way I liked. You can see most of the settings I chose in the screen shots above.
Usage
I like this system because it puts a ton more relevant information in one place. The simplified version Victron provides is good, but having things like voltage and frequency allows me to see if there is a transient problem or other issue.
One of the features that was added recently is the bars you see on each square. These are configurable, and can take some time to setup, but I think they're worth it. They're a graphical representation of the various warning and maximum power amounts for things like shore power, generator, inverter, and more.
You'll have to go look up all of the various limits for your equipment, and then input them here. It's another great way to see a representation of how your system is working quickly - if the bars are "full" or close to one of the warning marks, you might want to look into things or monitor it more closely.
One of the great optimization features is the ability to click on the tiles on the main screen and get quick controls and details for each. You can see that represented above by the grey squares on each tile. Let's click into each and see the details.
One of my favorite ones is the quick options for the AC Input, specifically Shore Power. This allows me to switch the input current limit very quickly instead of navigating to this in the default Victron pages and holding down the plus sign for a while. I visit a decent amount of places where the power is crappy, or only 30 amps, so being able to switch quickly is awesome.
You can also see all of the data that is out on the main panel and a little more detail.
The inverter detail page delves a bit deeper into the stats showing input and output voltages, frequencies, currents, and power in watts.
I use this screen for the big buttons on the right every so often. If I happen to be in a charge cycle with the generator running, and I need to shut the generator down or leave the boat, there is no way that Victron provides to let the generator cool down, and shutting it down when it is running hard is not cool. So I flip things to "Inverter Only" and that drops the load off the generator, albeit still quite quickly. I can then cool down the generator and shut it down.
AC Loads isn't really that useful in my setup. This data is viewable on the main screen.
The battery detail page has a few more bits than the main page - mainly consumed amp hours, and the state.
I have my system setup to show my "DC System" which allows me to monitor how much power is being used by the DC-DC converters that take 24 volts from my main battery bank and converts it into 12 volts for the various DC loads on the boat (you can see my overall system design at Kaos LiFePO4 electrical system v1) and any other native 24 volt loads.
It is also showing the Lynx Shunt I have in the secondary distribution bus for my 12 volt system. I haven't figured out how I might be able to show that on the overview page or elsewhere, but it shows up here.
If you prefer the mobile summary screen, that one has been modified too. Lots more info all in one place.
For more complex systems, there are dedicated versions of the summary screen to accommodate showing all of the inputs/outputs and data. The above example is for a DC coupled system that could include an AC charger, alternator, fuel cell, wind generator and PV charger. I think it would be interesting if you could enable/disable each of those objects - I'm guessing there's a way that I've not probably found.
There's a similar version for an AC Coupled system that includes PV/solar on input/output, AC in/out loads, a wind generator and more.
Victron VRM Push Alerts
Victron VRM is an amazing way to be able to monitor your electrical system remotely, but getting alerts has always been a bit lackluster. The only method available has been via email, which is pretty limiting.
Now you can choose to enable "Mobile push notification" from whatever device you're connected with.
The push notifications are pretty quick and have worked well so far.
You can even get notifications to a browser on a computer. You can also manage other connected devices - you can see my iPhone there.
Having push alerts is great as an alternate notification path, but it would sure be nice to have SMS/text and even an API that you can leverage and connect to other industry standard notification and monitoring systems.
The Victron monitoring ecosystem continues to grow, and I love the power that GuiMods provides for the displays, plus the VRM push notifications to keep me updated on alarms remotely.

One thing Steve didn’t mention in here that’s an even more awesome ability of the guimods framework – inline tank and temperature monitors from that main dashboard!
(Ignore that we’re out of fresh water – we got pumped out and emptied the fresh water tanks while we are away from the boat for a bit, so I’m pulling this up remotely over the VRM remote console. )
Thanks for posting your screens and adding the details about tanks and temperatures. I have those elsewhere and like they way they are displayed, but I know of a number of folks including @deregtd who like having all of this data on one screen. Keep packing it in!
Great article. Does this mean there is a way to get data from Smart Lithium batteries through the VRM? I get more data on my battery stats thru the Bluetooth interface than I do thru my Cerbo / VRM interface. I have wanted to be able to see battery temp and cell voltage data on the VRM. And my boat is 800 miles away, well beyond Bluetooth range.
This looks super useful! Where is the data for tank levels coming from though? I don’t remember that being part of the system but perhaps you just focused on the lifepo4 aspects in the recent article. Looking for a reliable holding tank monitor solution and would be neat if it integrated with this UX and the rest of the Victron data perhaps.
Mike, the Cerbo has inputs for up to four resistive tank sensors on its own, and you can add tank sensors of other kinds by using Victron’s GX Tank 140 sensor box, which connects to the Cerbo (or other Venus OS device using USB. A good article about it on Panbo recently: Tank monitoring with Victron GX Tank 140, accuracy matters - Panbo

Great article. I got the updated display without any issues. At some point, I would like the graphic to be able to show the Wakespeed500/Alternator as a tile. Not sure if that can be done. (My other Victron wish is to be able to prioritize PV charging over shore power when it is available and appropriate. Certainly not germane to this thread)
Thanks again…
With the Wakespeed integration into the Lynx BMS, I wonder if it isn’t something that could be done, although it would require the Lynx I would imagine. I have both, although I’m not using the Wakespeed right now. Something to add to the list of stuff to test…
@bearcem, Victron recently added a solar priority mode, if you have a Multiplus shore charger/inverter. (Google for details). Before that you could kind of achieve the same thing by changing voltages in charge profiles but it wouldn’t be as convenient.
Re: Wakespeed on GuiMods - I would like that too! It looks like GuiMods already has an alternator tile (which will be hidden by default when its inactive). I haven’t started our engine up yet, but our Wakespeed is integrated with the CerboGX and shows up in the device list on the GX display. So I’m hoping it will show in GuiMods - I’ll be testing that soon.
FYI the alternator does show up as a tile. Very nice (although I’d like different data displayed - I’m considering making my own GuiMods fork to customize the display data).
Also worth noting: I’m turning off auto-update and would recommend not using that. GuiMods author pushed out a bug yesterday which caused the display to white screen of death (crash / not work basically). My first thought was we had a hardware issue or electrical issue. Fortunately I didn’t waste too much time investigating wiring before it magically fixed itself (about 14 hours later) when it auto-updated with the fix.
Our electrical display is used daily and is a critical component so I don’t think doing updates instantly and automatically in the background (there’s no way to get notified when it happens either) is a good idea for us given how critical it is. With manual updates, we would’ve never picked up the buggy release.
I had the same issue with GuiMods where my display was unusable for about a day due to the bug. White screen, no response, etc.
I agree that automatic updates are probably not a good idea after seeing this!
thank you for sharing this info. Do you know if the Temperatures probes plugged into my Cerbo GX will share and show on the Nema 2000 network?
It looks like they don’t support that, at least as of this article I found.
I noticed some folks use wireless temperature sensors e.g., the Ruuvi Temp tags. That information is displaying on their Cerbo Dashboard. Do you know how they are doing this?
Ruuvi tags connect easily into the Cerbo via bluetooth. Example video: https://www.youtube.com/watch?v=xj_aOZH2lPg
I love Ruuvi tags. I have them in various different spots that are hard to get normal wired sensors into. I’ve used both the Victron Cerbo and Signal K on a PC to gather the data, although Signal K is a bit more flaky and difficult to configure.
Thank you much. Thats pretty cool. Makes me want to add all sorts of other sensors.
I have a few of the Bluetooth Govee Temp sensors already. Are they compatable with the Cerbo also?
I am not at the boat but wasn’t able to try from here but…
I don’t think the Govee sensors are compatible with the Cerbo. Generic bluetooth sensors could potentially work with Signal K but there might be some software tweaks required to get them working. I’ve not used Govee’s temp sensors - I have a bunch of their lights aboard though.
Another avenue is Home Assistant. I use it extensively for controlling lights, but it can also output pretty much anything it is gathering over to Signal K which could then put it on another network (NMEA 2000) if you wanted it to. You could use the Govee temp sensor to Home Assistant too just natively - the Home Assistant mobile app is pretty nice.
Thank you much for the info everyone. Also would like to monitor the AC Voltage on the dashboard. Would be great to see exactly what voltage the generator/Shore Power is coming in at.
Is that a setting or a device I need to measure and receive that info?
Thanks again
Right now the standard Victron displays won’t show that. The article this thread is about (scroll back up to the top) adding a 3rd party package to help show that.
