AURUM – Solar Surplus Optimizer for Home Assistant

Home-Assistant-Integration: schaltet Buderus-/Bosch-/Junkers-Wärmepumpen über EMS-ESP bei PV-Überschuss in den PV-/SG-Ready-Betrieb. Akku-Vorrang, Solcast-Prognose, Kompressorleistung folgt dem Überschuss, Beobachtungsmodus, Dashboard-Karte. Erfolgreich getestet mit Buderus WLW186i. English docs included.

All-in-One Energy Management System for Home Assistant - Optimize EV charging using PV surplus and energy price forecasts.

A deterministic, fail-safe Smart Grid (SG-Ready) heat pump controller using Home Assistant, ESPHome, HomeWizard and Shelly to convert PV surplus into thermal storage (fully local).

Run a pool pump, water heater or any switchable load on PV surplus, with a guaranteed minimum runtime per day. Forecast-aware, battery-aware, built for balcony solar and limited inverters.

Home Assistant integration: one plan for your PV surplus — departure-aware EV charging (any brand), home battery and devices by priority, with cheapest-hour grid fallback (Tibber, Nordpool, …)

IP-Symcon-Modul für go-eCharger: PV-Überschussladen, PV-Anteil, manuelles und hybrides Laden mit Netzbezugsbegrenzung.

Manage your surplus solar power with easy to configure devices.

Python application which reads energy production and consumption information and controls the heat pump for warm water, the heat pump for heating and the car charger.

Home Assistant custom integration to charge your EV using solar surplus only

Experimental dynamic 1↔3-phase charging for WARP More-flashed AC011K-AE-25 wallboxes

PV-surplus controller for an RTX 3070 running NiceHash: Shelly Pro 3EM, power limits via nvidia-smi, temperature safety stop

Use PV surplus for Bitcoin mining: a Shelly Pro 3EM script sets the Antminer power target via Braiins OS+ – no extra computer

Use free solar power for cooling and hot water: Node-RED flow that switches the cooling function of a Proxon heat pump (Modbus RTU) and the T300 Boiler Boost (Shelly via MQTT) based on PV power, battery SOC and outside temperature – with hysteresis, Pushover alerts and Dashboard 2.0.

Home Assistant integration that shares PV surplus among prioritised loads

Local, cloud-free SG-Ready heat-pump control from PV surplus. Reads your grid meter, decides when there's genuine surplus, switches a Shelly relay. Fully observable, EN/DE web UI that explains every decision.
