:description: Simple visualisation of Home Assistant states using a Neopixel stripe
|
|
:image: /cookbook/images/infostrip-detail.jpg
|
|
:keywords: Neopixel
|
|
|
|
Showing the current status of sensor states using a Neopixel (WS2812B) strip is a simple way to communicate states to the user.
|
|
Compared to a dashboard screen the infostrip can only communicate the information like a binary sensor.
|
|
|
|
- color (e.g., red = error/warning, orange = warning, green = ok, blue = active)
|
|
- intensity (off, scaled brightness)
|
|
- mode (continuous vs. flashing, flashing or strobe is not recommend)
|
|
- light position on stripe

Home Assistant configuration
|
|
----------------------------
|
|
|
|
The automation to show the CO2 warning light (e.g. red if CO2 > 1000 ppm) is done in Home Assistant, but could also be implemented using ESPHome :ref:`Automations <automation>`.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Turn on a light with the related color
|
