MQTT
The integration MQTT can be configured within the settings.
You need to enable the MQTT Integration inside Home Assistant.
As soon as you have enabled the MQTT integration, you can proceed with the MQTT setup of yahac.
Configuration
Using the Settings entry of the yahac menu, you will see again the configuration window.
Provide all your relevant data and save. Don't forget to hit the checkbox to register yahac a entity into Home Assistant and restart yahac once.
MQTT Integration
During the startup, yahac will create (if not already done) a new MQTT integration. Within this integration, you will find all your yahac clients.
yahac sensors
Each yahac instance you run on your computers will create automatically a new sensor. This sensor can now be used in automations, e.g. keep on a light or heating, etc.
The naming of each sensor has the prefix 'yahac_' and the computers' name without any special characters.
