@ -6,8 +6,30 @@ The mod takes the colors from the first few pixels and sends them to the lights.
## Configuration
First, enter how often the data will be sent to the lights (in ms).
Then enter the IPs for the lights to be controlled, in order. There is currently a limit of 10 devices that can be controled, but that number
- Interval (ms)
- How frequently to update the WiZ lights, in milliseconds.
- Setting too low may causse ESP to become unresponsive.
- Send Delay (ms)
- An optional millisecond delay after updating each WiZ light.
- Can help smooth out effects when using a larger number of WiZ lights
- Use Enhanced White
- Enables using the WiZ lights onboard white LEDs instead of sending maximum RGB values.
- Tunable with warm and cool LEDs as supported by WiZ bulbs
- Note: Only sent when max RGB value is set, need to have automatic brightness limiter disabled
- ToDo: Have better logic for white value mixing to better take advantage of the lights capabilities
- Always Force Update
- Can be enabled to always send update message to light, even when color matches what was previously sent.
- Force update every x minutes
- Configuration option to allow adjusting the default force update timeout of 5 minutes.
- Setting to 0 has the same impact as enabling Always Force Update
-
Then enter the IPs for the lights to be controlled, in order. There is currently a limit of 15 devices that can be controled, but that number
can be easily changed by updating _MAX_WIZ_LIGHTS_.
## Related project
If you use these lights and python, make sure to check out the [pywizlight](https://github.com/sbidy/pywizlight) project. I learned how to
format the messages to control the lights from that project.
