# 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
[Tuya Convert][Tuya-Convert] to flash them without the need to take them apart.

## Wall Switches

I currently use the [Sonoff T1][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`.
