 # EspHoMaTriX (ehmtx)
 A simple DIY status display, build with a flexible 8x32 RGB LED panel implemented with [esphome.io](https://esphome.io)

 # Introduction
 
 There are some "RGB-matrix" status displays/clocks out there, the commercial one from Lametric and some very good d.i.y.-alternatives. 
 
 - [LaMetric](https://lametric.com/en-US/) commercial ~ 199€
 - [Ulanzi TC001](https://de.aliexpress.com/item/1005005008682055.html) commercial ~ 50€

-- [PixelIt](https://docs.bastelbunker.de/pixelit/)

+- [PixelIt](https://docs.bastelbunker.de/pixelit/) (project is under active development)
 
 The other d.i.y. solutions have their pros and cons. I tried both and used AwTrix for a long time. But the cons are so big (after my opinion) that i started an esphome.io variant. Targeted to an optimized homeassistant integration. The main reason, for me is the homeassistant integration!

 ## icons/animations
 Download and install all needed icons (.jpg/.png)/animations (.gif) under the "ehmtx"-key. All icons are automagically scaled to 8x8 on compile-time. But this doesn't work well for gif's!
 You can also specify an url to directly download an image file. The urls will only be downloaded once at compile time, so there is no additional traffic on the hosting website.

 Removes a screen from the display by icon name. If this screen is actually display while sending this command the screen will be displayed until its "show_screen"-time has ended.

+For example if you have multiple icons named weather_sunny, weather_rain & weather_cloudy, you can issue a del_screen weather_* to remove whichever screen is currently in a slot and replace it with a new weather screen.

 ### use in automations from homeassistant
 
 The easiest way to use ehmtx as a status display is to use the icon names as trigger id. In my example i have an icon named "wind" when the sensor.wind_speed has a new state this automation sends the new data to the screen with the icon named "wind" and so on.
