Victron PV Automation with Node-RED

I want to take my Victron-based PV installation to the next level by driving everything through Node-RED on Venus OS Large, hosted on a Raspberry Pi. The hardware stack includes the Victron system itself, a Seplos battery pack and a heat pump. Your job is to build, test and document a set of Node-RED flows that bring the whole setup into a single, smart, fully automated loop. What I need automated • Battery management, heat-pump control and overall energy monitoring, all visible in one dashboard. Battery-side features • Charge/discharge scheduling aligned with tariffs or solar production • State-of-charge monitoring presented in real time • Peskshaving logic that caps grid draw during peaks Heat-pump controls • Precise temperature regulation • Automatic heating/cooling mode switching • Energy usage tracking • Energy regulation and optimised usage based on available solar or battery reserve Key technical notes • Environment: Venus OS Large, Raspberry Pi, Victron dbus, MQTT and Modbus where relevant • All flows should survive reboots and be clearly labelled so I can tweak them later. • Any scripting or custom nodes must be provided with clear comments. • A short read-me explaining installation and backup/restore steps is essential. Success criteria 1. Flows import cleanly and show no Node-RED errors. 2. Battery, inverter and heat-pump metrics appear in the dashboard within 5 seconds of refresh. 3. Automated actions (charge scheduling, mode switching, peak-shaving cut-off) trigger reliably in a live test spanning at least one full solar day. Once everything runs smoothly, please hand over the final flows, documentation and a quick video or screenshot walk-through so I can confirm the result.
