Generelles

Auf diesem Raspberry läuft ein Brickd und ein Brick-MQTT-Proxy um die Sensordaten von dem Tischtennisschläger ins MQTT zu bringen.

Es ist ein OverlayFS via raspi-config konfiguriert.

Hardwaremodule:

Modul	ID
Master Brick 2.1	6rK33e
Sound Intensity Bricklet	voE
UV Light Bricklet	xpa
Accelerometer Bricklet	v6Z
Temperature Bricklet	tfj

brickd

brickd läuft auf dem RaspberryPi und kommuniziert via USB mit den Tinkerforge Modulen. Via TCP auf Port 4223 kann man die Daten abfragen. Tinkerforge stellt Bibliotheken für diverse Programmiersprachen bereit und bietet auch eine GUI brickv dafür an.

Die Installation ist am einfachsten über die von Tickerforge bereitgestellten APT Repos. Siehe hier: https://www.tinkerforge.com/de/doc/Software/APT_Repository.html#apt-repository

Danach einfach via apt install brickd installieren.

brickd MQTT Proxy

Tinkerforge stellt auch ein Programm bereit um die Daten zu einem MQTT Server zu schicken. Installation via apt install tinkerforge-mqtt ebenfalls aus den Repos, siehe oben. Mit dem Paket kommt ein Service tinkerforge_mqtt.service.

Konfiguration

/etc/tinkerforge_mqtt.cmdline:

--broker-host homeassistant.local
--broker-username mqtt_tennis
--broker-password SECURE
--init-file /etc/tinkerforge_mqtt.init
--debug

/etc/tinkerforge_mqtt.init:
