Hi, if a 3rd party ev charger or heat pump is used with 3.80-25+ is it possible to use Limitation of Power Consumption (LPC) through eebus towards it? For the german regulation §14a EnWG it is required that chargers and battery chargers support a limitation of power consumption. While this works …

Hi @aaxc , the LPC limit can be indeed controlled via Node-RED. There will be no official EEBUS node, but it can be achieved by using the “Custom Control” node. At the EEBUS device, the following paths need to be controlled: /Ac/Limits/Consumption/Power – write 4200 for 4.2 kW /Ac/Limits/Consumptio…

Hi @aaxc , our EEBUS integration does support the LPC use case for limiting connected EEBUS devices already and we are aware of this requirement in Germany. However, at this moment, there is no logic in place to receive and forward such curtailment signals to an EEBUS device. There might be the poss…

Hi @aaxc , what I meant was not listening to the input state of the Multi RS, but using a digital input of the GX device as signal source. Anyways, as it is a potential-free signal coming from the RSE, you should be able to feed the signal to both the Multi RS and Cerbo GX digital input.

Hi @ptrenz , regarding using a digital input on the GX to trigger LPC via EEBUS for a wallbox or heat pump… How would I then send the signal to the devices? Will there be a Node-Red node for EEBUS?

Thanks a lot! I will have a chance to test it in about 2 weeks when I connect my heat pump and wallbox.

Will the eebus implementation support LPC functionality?

Hi Phillipp,

a Nodered solution wouldn‘t work because of this issue.

At the moment I don‘t have an eebus charger or heat pump
