Transparency Notice: This repository is an independent fork maintained by Carbanog. I am not a professional programmer; I am an enthusiast with basic knowledge who has developed this version primarily with the help of AI to meet personal stability needs that I couldn't find in other versions. Provided as-is, without warranties or official support. Use at your own risk.
- Maintenance: Active (for personal use and experimentation).
- Primary Goal: Total stability on PLC/WiFi networks using a Data Coordinator (a single request for all sensors).
- Original Base: Based on the work by Rain1971, currently discontinued.
This integration allows you to control and monitor your V2C Trydan charger 100% locally via its HTTP interface. The core has been rewritten to minimize requests to the charger, avoiding crashes and connection errors frequent in PLC-based installations.
- No external dependencies — does not use
pytrydan, communicates directly via HTTP - PLC stability — native retries, 20s timeouts, silent logs on temporary failures
- More entities — Binary Sensors, ContractedPower, descriptive ChargeState and more diagnostics
- Documented services — with sliders in HA UI
- Modern architecture — uses
ConfigEntry.runtime_data, no legacyhass.data - JSON fix — automatically repairs malformed firmware responses
- Static IP: It is mandatory to assign a fixed (static) IP address to your V2C Trydan charger in your router settings. If the IP changes, the integration will stop working.
- Updated Firmware: It is recommended to have the charger updated to the latest official version from V2C.
- HACS: Add this repository as a "Custom Repository" in HACS.
- Restart: Restart Home Assistant.
- Configuration: Go to Settings → Devices & Services → Add Integration → Search for V2C Trydan.
- IP: Enter your charger's static IP address.
