ESPHome adds a Bluetooth connection to Delta AC wallboxes, letting makers start or stop a charging session and read the charger’s state, power, energy and charging time. The connection also exposes the charger’s model, serial number and firmware versions.
The component pairs and signs in with the configured PIN and password before polling. An optional time source keeps the charger’s clock in step. The accompanying guide covers finding its Bluetooth address and configuring the readings and controls.
