+# My ESPHome Config
+
+[ESPHome](https://esphome.io/) is a project for controlling ESP8266 and other
+similar chips. These are commonly used in Chinese smart devices.
+
+This firmware works very well with Home Assistant which is why I use it.
+
+## Smart Bulbs
+
+I currently use the [BlitzWolf_BW LT21](BlitzWolf_BW-LT21) bulbs. The ones I
+bought all came with an old version of the Tuya firmware which allowed me to use
+[Tuba Convert](Tuya-Convert) to flash them without the need to take them apart.
+
+## Wall Switches
+
+I currently use the [Son off Ta](Sonoff-t1) switches with varying numbers of
+buttons.
+
+In order to differentiate between single, double and hold clicks, I don't
+publish the internal binary sensor state (on of off). Instead I create a text
+sensor that can have the states of "single", "double", "hold" or "" (empty
+string).
+
+In order to use this as a home assistant trigger, I do set `Trigger Type` to
+`state`, then the entity is the name of the text sensor.
+
+I leave `from` and `for` blank, and set `to` to `single`, `double`, or `hold`.
