WLED


WLED is a fast and feature-rich implementation of an ESP8266/ESP32 webserver to control NeoPixel (WS2812B, WS2811, SK6812, APA102, and similar) LED’s.

Configuration

This integration can be configured using the integrations in the Home Assistant frontend.

Menu: Configuration -> Integrations.

In most cases, the WLED devices will be automatically discovered by Home Assistant. Those automatically discovered WLED devices are listed on the integrations page.

If for some reason (e.g., due to lack of mDNS support on your network), the WLED device isn’t discovered, it can be added manually.

Click on the + sign to add an integration and click on WLED. After completing the configuration flow, the WLED integration will be available.

Lights

This integration adds the WLED device as a light in Home Assistant. Home Assistant treats every segment of the LED strip as a separate light entity.

Only native supported features of a light in Home Assistant are supported (which includes effects).

Sensors

This integration provides sensors for the following information from WLED:

  • Estimated current (in mA).
  • Uptime (disabled by default)
  • Free memory (in bytes, disabled by default).
  • Wi-Fi Signal Strength (in %m disabled by default).
  • Wi-Fi Signal Strength (RSSI in dBm).
  • Wi-Fi Channel (disabled by default).
  • Wi-Fi BSSID (disabled by default).

Switches

The integration will create a number of switches:

  • Nightlight.
  • Sync Receive.
  • Sync Send.

Services

Currently, the WLED integration provides one service for controlling effect. More services for other WLED features are expected to be added in the future.

Service wled.effect

This service allows for controlling the WLED effect.

Service Data Attribute Required Description
entity_id no A WLED entity ID, or list entity IDs, to apply the effect to. Use entity_id: all to target all WLED entities.
effect no Name or ID of the WLED light effect.
intensity no Intensity of the effect.
speed no Speed of the effect. Number between 0 (slow) and 255 (fast).
reverse no Reverse the effect. Either true to reverse or false otherwise.

A list of all available effects (and the behavior of the intensity for each effect) is documented in the WLED Wiki.
