This article shows how to write your own home-assistant integration. When I wanted to write a mock for home-assistant it become really complicated. For a newbie to home-assistant the documentation was not very helpful. Or to be fair a simple and complete step-by-step guide would have been nice.

Requirements

• I used homeassistant-core commit hash 24ea5eb9b583e44aa170bd8806ddecce7ac09175 which was the latest in the moment of writing.

From scratch to configuration

Normally it should be easy to extend a popular platform like homeassistant with your own extension. For learning I like to build a waterheating device which is implemented as a heatpump-mock which can be integrated into homeassistant. I like to use the predifined Entity Water heater. You can also read the offical documentation for more information.

Its well known that JMeter can run in a distributed environment. This means that the complete environment has one controller (called master by JMeter) and multiple runners (which are called slaves by JMeter). I prefer to use the words controller over master and runner over slave. Even JMeter is an old tool it was difficult for me to set it up, because a simple guide for setting up was missing and the terms used by JMeter were misleading for me.

Der Dummschreibtest ist damit hoffentlich bestanden.
