We have a 200va generator and we are installing a new 7320 MKII and 890MKII gateway to control the generator from the phones and read the fuel levels. Have someone gotten it right to read the data from the Deep Sea controller like Status, or fuel levels?
Hey all,
For anyone coming across this question, actual status:
Hello Victron,
We are the Dutch distributer for DSE and i get some questions about the DSE4520MKII. This is the new controller which is also configurable as 4510MKII but then it is not recognized as a 4510MKII as the base unit is the 4520MKII and that is read by the modbus page as you describe in the manual;
By utilising the identification values found in Modbus registers 768 and 769 (GenComm Page 3, Register offsets 0 and 1), the GX device automatically detects the presence of a DSE controller.
So if you can add the correct identification value in the Cerbo firmware you can use this controller also.
If you have questions about this let me know.
Met vriendelijke groet,
Kind Regards,
Mit freunlichen Grüssen,

Hi @Cyon, here's what we did for a remote site with a Genset having a DSE4620 unit:
Furthermore, we use additional digital outputs of the DSE to monitor if the genset is in auto-mode (required for the Cerbo GX to crank it) and if there is any error (general error signal). These could also be read out by the Cerbo GX and viewed from VRM under "Advanced", although we choose to log them via an external PLC to an InfluxDB database and visualise them together with other relevant values from the Victron System in a Grafana dashboard.
The Victron ecosystem is an insanely powerful platform due to its documentation and open interfaces. Next, we'll extend our genset with a DSE855 ethernet interface to feed more in-depth live metrics into our dashboard via ModBus.
I think it is much easier not to link the systems directly with each other (more than necessary), but to prepare the necessary metrics together via an external tool such as Grafana. In Grafana there is also a powerful alert management system.
Hey both,
Matthijs here, from Victron. We might be able to work together here a bit:
We've recently finished implementing support for another brand of generator controllers, ComAp. There we use ModbusTCP, and a ComAp ethernet accessory. See my Venus OS v3.10 beta series posts for the details on that.
We're very keen to do the same for DSE, as well as Deif for that matter. Looking for a technical customer to get that done with together. What we need is a system that is standing somewhere; and an approval for us to login remotely and create the required profile.
I've read up on the DSE4620 as well as its accessory DSE855 just now, and perhaps one of you familiar with DSE can confirm me:
1. DSE4620 only comms port is USB - correct?
2. DSE seems to not publish this protocol / most efficient way to get this going is to go over the DSE855 ethernet module?
Please let me know if you're interested.
all the best, Matthijs
ps. for any software developer, this is the changes we had to make to add ComAp support: https://github.com/victronenergy/dbus-modbus-client/commit/f1dedd198d9eb0ef735fa2df4e048291d12219d1. Not that much code actually. Most work for us is to find a generator, understand the DSE product range, decide on the protocol and then get and read and understand the documentation.
And then actual implementation is very quick.
It doesn't have an Ethernet port but it does have RS485.
And I have one next to my house-under-construction, hooked to a Victron inverter bank.
Hi Matthijs,
We're currently exploring this concept!
Our systems at the moment commonly have a DSE7420 mkII controller connected to the diesel genset, with the remaining battery/solar system being Victron/Cerbo GX centred.
From what I've gathered, the 7420 mkII can transfer data:
a/ MODBUS RTU over RS232
b/ MODBUS RTU over RS485
c/ MODBUS TCP over Ethernet
It seems possible to run either RS485 or Ethernet to the Cerbo GX.
We should be able to set up a system with Cerbo GX and DSE7420 which can be accessed remotely if you are still interested.
Let me know if you need any further information,
Best Regards,
Jethro
Hi @Cyon and @jleverf, for you to note: @mvader (Victron Energy) and I are actively working on a Modbus TCP integration for DSE controllers and making good progress.
@jleverf: I'm currently testing with DSE4620 controller. If you could set up cabling and provide me with some form of access, this would be very helpful!
Let me know if you'd like to set up a call to discuss access and timing/availability or anything else!
I have access to the following
DSE 4520 and a DSE 855 USB to Ethernet that we can use for testing
Would like to have this connected to the Cerbo GX
Hi all, we just published the release candidate v3.20~12, which adds support for eight DSE models: https://community.victronenergy.com/questions/237457/venus-os-v3209-available-for-testing.html
If you have a DSE model, which is not listed and we should add support for, then please reach out.
Update: With release of v3.12, the DSE integration is now officially available. Currently supported models:
Hi @Brittney.Woodgate, we're currently working on a slide deck presenting all features of the integration. Meanwhile, you can already find some information within the Cerbo GX documentation here: https://www.victronenergy.com/media/pg/Cerbo_GX/en/connecting-supported-non-victron-products.html#UUID-7d8b2715-75d6-b9fc-e086-9d9e0fb49d7c
Is this possible for the DSE L401 MKII or should I hold off and get one of the other supported models?
Thanks
So I found a DSE 8610 MKII for £259 which has built in ethernet, so no need for the DSE855.
If anyone wants an L401...
No worries, yeah I think the swap out will simplify things. I guess I may have been in a minority with the L401, although it is a cheaper option, but when considering the need for the DSE855 on top, maybe doing as I did, and looking for an 8610 MKII or other Ethernet ready already supported DSE controller makes more sense.
Can we please add DSE4520.
Hi @Greendovefarms, I got the information from DSE, that the DSE 4520 unfortunately does not have the option of Telemetry Start via Modbus TCP. Meaning, you won't be able to control the genset.
Hi @Stephen Gannon, I cannot say for sure. But I found a setting in the manual under "2.2 Module", which says:
Auto Start: Converts the DSE4520 MKII into a DSE4510 MKII. This allows the module to start in manual mode, and on activation of remote start signal when in auto mode.
So, it seems like remote start does work for the MKII. It may even be already compatible, as we do support the DSE 4510 MKII. If you test it, please keep me up to date.
Another update: We are currently working on supporting the DSE 4520 MKII. As this specific model does not support starting and stopping via Modbus, it will use one of the GX relays for the start/stop signal.
Hello, Sorry for the long delay. I never got any emails. so we changed our module to the 7320 MKII and the gateway (0890-04)has an MQTT, I created an HA svr to get the MQTT, but I'm struggling, the MQTT is connected but I don't get any info from the generator.
PS: I'm in IT but still need to learn dev thins.
Hello all.
So I got the controller to connect to my Home assistant. But I need to load the sensor manually.
how will the code look?
Is it possible to get support for DSE6120? We have installed the DSE855 but it does not seem to be recognised by the Cerbo GX
Hi, which MK-version do you have? We recently added support for DSE 6120 MKIII with v3.20~45, which is available in the Beta release (formerly: Release candidate) update feed.
Hi are we able to get the DSE4520 MK2 added to the list or is the DSE4510 mk2 a typo
Hello, as written above, according to DSE support, the DSE 4520 MKII does not have remote start/stop capabilities and can therefore not integrated, sorry.
Update: There seems to be a setting at the DSE 4520 MKII, which allows remote start. Manual chapter "2.2 Module" says:
Auto Start: Converts the DSE4520 MKII into a DSE4510 MKII. This allows the module to start in manual mode, and on activation of remote start signal when in auto mode.
If above is true, it may already be compatible, as DSE 4510 MKII is supported. Otherwise, we can probably add support for it.
I have had success with another site with a DSE7420 mk2.
Also are we also able to get the DSE7450 added to the list as well ?
thanks
Hi @Lawrence, yes: We are currently working on supporting the DSE 4520 MKII. As this specific model does not support starting and stopping via Modbus, it will use one of the GX relays for the start/stop signal.
Tried the same setting to Auto Start, on a 4520MK2 no success. Tried an firmware update from 4520MK2 to 4510MK2. Unfortunately the Config assistant wont let me. the VRM system is online and the DSE Webnet as well for testing if needed.
Hello everyone,
Would it be possible for me to install a DSE4520 and just monitor it but not have an automatic start via mqtt. But only via remote start cable?
Hi all, due to the high demand, we are right now working on adding support for the DSE 4520 MKII. As this specific model does not support starting and stopping via Modbus, it will use one of the GX relays for the start/stop signal. Therefore, it will require some additional wiring in contrast to the other DSE models. I will keep you informed.
