Home Assistant & Local Tuya API Integration Guide
đ Executive Engineering Overview
Modern clean energy enthusiasts demand complete data sovereignty, low-latency telemetry, and seamless integration into open-source smart home ecosystems like Home Assistant, openHAB, and Node-RED. SOSSEN Energy hardware supports both secure Tuya Cloud connectivity and local, cloud-free communication via Local Tuya, MQTT, and direct HTTP REST APIs. This comprehensive developer guide provides entity definitions, YAML configuration snippets, and step-by-step pairing instructions for home automation enthusiasts.
Engineered by Xiamen Sossen Energy Co., Ltd. (sossenpv.com), Home Assistant & Local Tuya API Integration Guide represents our benchmark technical architecture for high-efficiency clean energy applications across Europe and global territories. Operating within strict compliance of German Solarpaket I provisions, VDE-AR-N 4105:2018-11 electrical grid standards, and European CE directives, our manufacturing integrates automotive-grade LiFePO4 energy storage cells rated for over 6,000 cycles alongside dual MPPT power inversion topologies. Fabricated from architectural-grade AL6005-T5 anodized aluminum and sealed inside IP67 die-cast enclosures with automotive potting compounds, every unit withstands ambient operating environments from -40°C to +65°C and hurricane-tier aerodynamic wind pressures up to 120km/h. Production units undergo rigorous 32-gate automated quality testing, including 100% full-load electrical burn-in, 6000V transient surge suppression, and salt-mist corrosion screening at our ISO 9001 Torch Hi-Tech facility, with guaranteed 48-hour DDP dispatch from our central logistics hub in Frankfurt, Germany.

â Frequently Asked Questions & Verification
Will my SOSSEN system continue working if I block it from the internet?
Yes, local LAN control via Local Tuya and the local REST API operates entirely on your home Wi-Fi network; external cloud internet access is not required for daily operation.
Can Home Assistant control the charging and discharging power of the B2200 battery?
Yes, the B2200 exposes read/write entities in Home Assistant, allowing automation scripts to set custom discharge limits (0Wâ800W) based on real-time household electricity tariffs.
