Hi everyone, during the winter months, rooftop PV often does not generate enough energy to keep an ESS battery at a healthy state of charge. If the battery remains at a low SoC for extended periods, this can be detrimental to battery longevity. A practical solution is to raise the ESS minimum SoC …

Hi Marc, good question. BatteryLife is definitely the closest built-in Victron feature, and for many systems it may be the better/simple choice. My service is not intended to replace BatteryLife for users who are happy with it. The difference is that BatteryLife dynamically adjusts the active SoC l…

Good point, Node-RED works well for this if you already have Venus OS Large running. My approach targets users who don’t want that dependency, and it also covers a few additional things (PV-production-based transitions, charge windows, DVCC limiting) that would make the flow a bit more involved. But…

[image] martintb: But for the basic use case, your flow looks clean and simple! For all other cases you can install other Nodered flows. I am using a flow to integrate a PV inverter with a shelly meter, and I have a flow to control my battery discharge—based on the season, the current SOC, an…

That sounds nice. Would you mind sharing your Solution for that use case? I am very curious about that.

Here it is. Please note that you also need to set a global variable global.vrmSiteId with you VRM access data. [ { "id": "1459d4d7551ca112", "type": "tab", "label": "SolarVorhersage", "disabled": false, "info": "", "env": [] }, { "…

Hi why not use batterlife in settings? That works the same right?

To Batterylife, or not to Batterlife. That is the question
