Hello guys, please when you implement possibility to write (and read) setting for Self-consumption on Battery. I need to create Node-RED flow to not drain my battery when EVCS is on manual mode :smiley: Thanks in advance.

Is there not way to create a feedback loop that just freezes/sets the min soc to what ever it is at that time?

I think it is possible, but it is much more complivated than use proposed feature.

Custom Input or Custom Control Node with Custom Input = com.victronenergy.settings and Measurement = /Settings/CGwacs/BatteryUse seems to be the right Option Number = 0 is for All system loads, 1 is for only critical loads.

Unfortunately, this register does not yet exist in the official “Modbus register List”… I’m currently considering this solution for winter operation.

yes, exactelly - this solution for winter time and for EVCS is something I want to program.

Seems it already works :slight_smile: [{A2FBEE74-5C06-4CD7-BD63-A7BDEA12D3AF}]

pourrait on avoir le detail sur ces nodes merci [image] ESS setting - Self-consumption on Battery Node-RED Seems it already works slight_smile [{A2FBEE74-5C06-4CD7-BD63-A7BDEA12D3AF}]

For which one are you looking for?

j’ai le meme probleme, mode manuel sur EV chargeur, vide la batterie. pouvais vous partager le json? merci

Here it is: [ { “id”: “de5c019c228bbd55”, “type”: “tab”, “label”: “EVCS battery drain protector”, “disabled”: false, “info”: “”, “env”: }, { “id”: “30d7c50cf35d48f7”, “type”: “victron-output-custom”, “z”: “de5c019c228bbd55”, “service”: “com.victronenergy.settings”, “path”: “/Settings…
