Monitor and control your Trek 4200 over Bluetooth
This Home Assistant integration reads Trek 4200 battery and power information over local Bluetooth and exposes its output controls. It can use a local Bluetooth adapter or an active ESPHome Bluetooth proxy. It requires Home Assistant 2026.10 or newer, and the power station allows only one Bluetooth connection, so the FSPower app must be closed.
