# WLED Binding

This binding allows you to auto discover and use LED strings based on the WLED project: https://github.com/Aircoookie/WLED (opens new window)

# Supported Things

Thing Type ID Description
json A bridge to a WLED device using the JSON API. Add this Thing first.
segment A segment is used to turn a LED strip or string, into 1 or more lights. Each segment is like a separate light globe that can have its own color or effect.

# Discovery

The auto discovery will find your WLED if your network supports mDNS and the UDP port 5353 is not blocked by a fire wall. Before discovering any WLED devices, you may wish to name them by providing a 'Server description' in the WLED web page, CONFIG>User Interface> setup page. openHAB will then discover and auto name your WLED bridge Thing to the name provided as the 'Server description'. Segments will be discovered with an Inbox scan after the bridge Thing is first showing up as ONLINE. Any segments that have been given a name in the WLED firmware, will be given the same name when discovery adds them to the Inbox.

# Bridge Thing Configuration

Parameter Description Required Default
address The full URL to your WLED device. Example is http://192.168.0.2:80 Y
pollTime How often in seconds you want the states of the LED fetched in case you make changes with a non openHAB app, web browser, or the light is auto changing FX or presets. Y 10
saturationThreshold Allows you to use a colorpicker control linked to the masterControls channel to trigger only using the pure white LEDs instead of creating fake white light from the RGB channels. Try setting the value to 12 or leave this on 0 for RGB strings. Y 0

# Bridge Thing Channels

Channel Type Description
globalBrightness Dimmer Changes the brightness of all segments at the same time.
presets String A list of presets that you can select from and will display -1 when no presets are running.
playlists String A list of playlists that you can select from and will display -1 when none are running.
presetCycle Switch Turns ON/OFF the automatic changing from one preset to the next. Only in V0.12.0 and older firmwares.
presetDuration Number:Time How long in seconds it will display a preset for, before it begins to change from one preset to the next with presetCycle turned ON. Only in V0.12.0 and older firmwares.
transformTime Number:Time How long in seconds it takes to transform/morph from one look to the next.
sleep Switch Turns on the sleep or 'night light' timer which can be configured to work in many different ways. Refer to WLED documentation for how this can be setup. The default action is the light will fade to OFF over the next 60 minutes.
sleepMode String Timed Light Mode selects how the light will fade or increase when the sleep timer is turned ON.
sleepDuration Number:Time Time it takes to change/fade to the target brightness.
sleepTargetBrightness Dimmer Sets how bright the light will be after the sleep duration time has expired.
syncSend Switch Sends UDP packets that tell other WLED lights to follow this one.
syncReceive Switch Allows UDP packets from other WLED lights to control this one.
liveOverride String A value of "0" turns off, "1" will override live data to display what you want, and "2" overrides until you reboot the ESP device.
sleepRemaining Number:Time Read only. The time that is left until the sleep timer has finished, 0 when it is not running.

fps Number Read only. The frames per second that the device is showing. Needs firmware 0.14.0 or newer.
syncSendGroups Number The sync groups this light sends to, as a bit mask: group 1 is 1, group 2 is 2, group 3 is 4 and so on up to 128. Needs firmware 0.14.0 or newer.
syncReceiveGroups Number The sync groups this light listens to, same bit mask as above.
mainSegment Number The number of the main segment.
ledMap Number Loads the LED map: 0 is ledmap.json, 1 to 9 are ledmap1.json to ledmap9.json. Write only, the device does not report the active map. Needs firmware 0.14.0 or newer.
liveActive Switch Read only. ON while another device or app sends live data (DDP, E1.31, Art-Net...). Needs firmware 0.14.0 or newer.
liveMode String Read only. The protocol of the live data.
liveSource String Read only. The IP address that sends the live data.
audioReactive Switch Turns the AudioReactive usermod on or off. Only works if the usermod is installed. The value is read from the device settings every 20 poll cycles.
audioSyncMode String Audio sync of the AudioReactive usermod: 0 off, 1 send the audio to other WLED devices, 2 receive the audio. Only works if the usermod is installed.

The bridge Thing also has the properties firmwareVersion, name, ledCount, architecture and brand when the firmware is 0.14.0 or newer.

Channels that were added to the binding are added to existing Things the next time the bridge connects. Channels that the firmware or the LEDs can not use, like whiteTemperature for LEDs without CCT, are removed from the Thing. If you update the firmware of the WLED device or change the LED type afterwards, restart the Things or re-add them to get the matching channels.

# Rule Actions

This binding has these rule Actions that can be used with the json bridge Thing:

Action Description
savePreset(int presetNumber) Saves the current state of the WLED string into a preset slot that you can specify.
savePreset(int presetNumber, String name) Same as above, but also gives the preset a name.
deletePreset(int presetNumber) Deletes a preset slot. Needs firmware 0.13.0 or newer.
reboot() Reboots the WLED device. Needs firmware 0.13.0 or newer.
getPresets() Returns a text with a line for each preset and playlist, with name, brightness, transition time, effects, colors and for playlists the presets, durations and repeat.
getPresetsJson() Returns the presets.json of the device with every setting of every preset.
savePresetState(int slot, String name, String json) Saves a preset with the content you give, like on, bri, transition (in 0.1 seconds) and seg, instead of the current state.
savePlaylist(int slot, String name, String presets, String durations, String transitions, int repeat, int end) Saves a playlist. presets is a list like "1,2,3", durations and transitions are seconds like "10,10,5" (one value is used for all), repeat 0 is forever, end is the preset to apply after the last run.
getSettings() Returns all settings of the device as JSON (/json/cfg).
getSetting(String path) Returns one setting, the path is the names separated by dots, for example um.AudioReactive.sync.mode.
setSettings(String json) Changes settings, the JSON only needs the settings that change. Some settings only work after a reboot().
setSetting(String path, String value) Changes one setting, for example setSetting("um.AudioReactive.sync.mode", "1") to send the audio to other devices.
getStateJson(), getInfoJson() Return the raw /json/state and /json/info.
getNodes() Returns the other WLED devices that this device found in the network.
getLiveLeds() Returns the color of every LED right now.
getEffectData() Returns what each effect uses (names of sliders and colors), from /json/fxdata.
syncClock() Sets the clock of the device to the time of openHAB.
sendState(String json) Sends a raw JSON object to the WLED /json/state API, for features that have no channel. The reply updates the channels.

In Xtend rules, you can use the Actions like this.

getActions("wled", "wled:json:XmasTree").savePreset(5,"Flashy Preset")
logInfo("wled", getActions("wled", "wled:json:XmasTree").getPresets())
getActions("wled", "wled:json:XmasTree").setSetting("um.AudioReactive.sync.mode", "1")
logInfo("wled", getActions("wled", "wled:json:XmasTree").getSetting("um.AudioReactive.sync.mode"))
getActions("wled", "wled:json:XmasTree").savePresetState(6, "Slow Rainbow", '{"on":true,"bri":128,"transition":20,"seg":[{"id":0,"fx":9,"sx":60}]}')
getActions("wled", "wled:json:XmasTree").savePlaylist(7, "Show", "1,2,6", "30,30,60", "2", 0, 0)
getActions("wled", "wled:json:XmasTree").sendState('{"seg":[{"id":0,"fx":9}]}')

# Sitemap Example

If you use the ADMIN>MODEL>Create equipment from Thing feature you can use the below and just change the name before the underscore to match what you named the segment Thing when it was added via the Inbox.
