# LED-Controller
Simple MQTT-LED-Stripe Controller based on https://wiki.keks.cloud/doku.php?id=projects:ledcontroller
# MQTT Topics
| Topic | Typ | Notice |
|---|---|---|
| led1/status | write-only | Retaines Message and Last will for MQTT Status, 1 = Online, 0 = Offline |
| led1/sync | read-only | Ignore all Setting for LED2 and mirrow LED1 color to the secound stripe, 1 = On, 0 = OFF |
| led1/1/mode | read-only | Set the Mode of LED1 |
| led1/2/mode | read-only | Set the Mode of LED2 |
| led1/1/speed | read-only | How fast the changes of the color will made, bigger number will be slower changes, for LED1 |
| led1/2/speed | read-only | How fast the changes of the color will made, bigger number will be slower changes, for LED2 |
| led1/1/color | read-only | Set Color for LED1, RRRGGGBBB, each color is a int between 000 and 255 |
| led1/2/color | read-only | Set Color for LED2, RRRGGGBBB, each color is a int between 000 and 255 |
# MODE
* on = Just one color, color can changed via MQTT
* fade = Fade
* off = Off (color 000000000)
