# TinkerForge WARP3 Pro

Source: https://docs.evcc.io/en/chargers/tinkerforge-warp3-pro

If necessary, WARP3's/WARP4's own automatic phase switching will be deactivated by EVCC when connecting to the wallbox (see [docs.warp-charger.com](https://docs.warp-charger.com/docs/mqtt_http/api_reference/evse#evse_phase_auto_switch_warp3)). Phase switching (1p/3p) is only possible on the WARP2 with an additional WARP Energy Manager, and not possible at all on the WARP1, since it does not support CP separation. RFID on the WARP1 is only available if an NFC Bricklet has been retrofitted. On the WARP4, EVCC can identify the vehicle by its MAC address if "Autocharge" or "Read state of charge" is enabled in the wallbox's ISO 15118 settings. Reading the vehicle SoC via ISO 15118 requires "Read state of charge" and is only available on the WARP4 Pro, since it needs the built-in energy meter. The ISO 15118 features require WARP4 firmware 2.12.2 or later.

Supported features: rfid, 1p3p, meter, mA, dim
