Possibility to Enable/Disable DESS from Node RED

Hello
Simple question. Is it possible to activate/deactivate DESS from Node Red?
As far as I know it’s currently only possible using the VRM right?
Or is also possible using GUI or GUI V2?
Reason for asking sometimes I want to takeover the control and MAX charge the battery or MAX sell to grid and I don’t have always access to the VRM.

There are DESS parameters which you can set with custom nodes.
You will just need to research what each does.

Yes I found these as well
But I just want to enable/disable DESS.
Similar to this switch on VRM

I use the standard ESS parameters such as GRID SET-POINT/MAX CHARGE POWER/MAX INVERTER POWER to load/unload the battery.

Use the API, see here: isOn

Thanks!

Unfortunately not available in the vrm-api node-red implementation (yet) right?

Or do I miss something?

No, but you can use a generic API (HTTP request/response) node to talk to VRM, just requires a bit more config.

Would be nice if the standard Victron Node Red API node would support this.
Thanks any how.

If we’re lucky, maybe @dfaber will add it to the never-ending todo list :slight_smile:

Maybe it make more sense the have the possibility to enable/disable DESS from CERBO-GX GUI?

There is…


@Victron,
please bring back the buy and sell option

In which case the “mode” local setting I posted earlier is likely that.

I cannot find it in my system. (Currently disabled DESS)
@Ton_Gans
Could you please tell me the “path” where I can find the menu item “Dynamic ESS”?

In nodered use a custom control node like so (sent to debug). See what yours is set to and if it changes when using VRM. Mine is 0, which I presume is OFF.

If DESS is disabled, you won’t find it in venus.
But otherwise it is: settings, ESS, DESS

I have it running. I have installed DESS node red, but disable it. But with this I can control it to be on (DESS) or off (ESS).
The way Nick wrote.

So once disabled you are not able to enable it again in VenusOS…
@dfaber is this by design or a bug (in GUI V2)?

It is by design/overlooked while implementing the current way. But I agree that toggling it from the gui would be handy. Stashing that on the todo list.

Thanks Nick this is working. I went for the HomeAssistant solution and I was able to make a switch to enable/disable DESS from HA
