JeeLink USB receiver LED control	Not working Local		LED on/off option not working; closed stale Saved copy The problem As I activated the lacrosse integration for my Docker Installation of Homeassistant, working with the Jeelink and the device is OK. But as mentioned here: https://www.home-assistant.io/integrations/lacrosse Turning ON/OFF the LED should work with the command: led boolean (Optional, default: false) That I integrated inside of my sensors.yaml like following: `platform: lacrosse #device: /dev/ttyUSB0 device: /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_AI03DAN7-if00-port0 baud: 57600 led: false` Using false oder true does not have any effect. ### What version of Home Assistant Core has … Excerpt saved from GitHub on 2026-10-23.
