ESPHome custom sensors and actuators

ESPHome is a product from Nabu Casa, like Home Assistant is also one of them.

Introduction

Not every sensor is available on the market as a complete product. Sometimes the only way is to create one yourself.
It’s also fun to build your own. It’s also possible to combine multiple sensors together with one ESP board.

The ESP board is a small mini computer with onboard WiFi. ESPHome makes it easy to program these boards.

You define for each ESP board the connected sensors in a template. In the template, you define your ESP board and which and how the sensors are connected. The sensor registers itself automatically to Home Assistant (or sends its data to a MQTT server).
