Server
Hardware
- Raspberry Pi seriell stumm geschalten
- ioBoard Projekt auf Github
Das ioBoard wird über das UART des Raspberry Pis angesprochen. Die Kommunikation zum Raspberry erfolgt über Ethernet, es werden keine weiteren Schnittstellen benötigt.
Software
- raspbian (wheezy)
- ser2net
- lighttpd (optional für Webclient)
- Webserver-Projekt Unterordner web
Konfiguration
In der Konfigurationsdatei /etc/ser2net.conf von ser2net aktiviert man folgende Konfiguration. Alle weiteren können auskommentiert werden:
2001:raw:120:/dev/ttyAMA0:9600 NONE 1STOPBIT 8DATABITS -XONXOFF -LOCAL -RTSCTS
Webserver konfigurieren
$ cd /var/ $ sudo chown pi:pi www/ $ cd cd /var/www/ $ git clone https://github.com/C3MA/uberschalter $ cd uberschalter/web/ $ make
Aktualiseren der lighttpd Konfiguration zu folgender (Muss ggf. erst installiert werden):
server.modules = (
"mod_cgi",
"mod_access",
"mod_alias",
"mod_compress",
"mod_redirect",
# "mod_rewrite",
)
#server.document-root = "/var/www"
server.document-root = "/var/www/uberschalter/web/www"
server.upload-dirs = ( "/var/cache/lighttpd/uploads" )
server.errorlog = "/var/log/lighttpd/error.log"
server.pid-file = "/var/run/lighttpd.pid"
server.username = "www-data"
server.groupname = "www-data"
server.port = 80
index-file.names = ( "index.php", "index.html", "index.lighttpd.html" )
url.access-deny = ( "~", ".inc" )
static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )
compress.cache-dir = "/var/cache/lighttpd/compress/"
compress.filetype = ( "application/javascript", "text/css", "text/html", "text/plain" )

Web
Auf dem RaspberryPi läuft auch Webserver um die Lampen zu steuern: (Zu erreichen im Raum-Netzwerk unter lampi oder 10.23.42.140.)

Mqtt
Doku
Folgende Stati werden in MQTT geschickt:
/room/light/3/command off
/room/light/1/state on
/room/light/2/state on
/room/light/3/state off
/room/light/4/state on
/room/light/5/state on
/room/light/6/state on
/room/light/7/state on
/room/light/8/state on
/room/light/3/command off
/room/light/3/command off
/room/light/3/command on
/room/light/3/state on
Linux Befehl:
$ mosquitto_sub -v -h 10.23.42.31 -t "/room/light/#"
Eine Lampe kann mit folgenden Schema geschalten werden: /room/light/<id>/command (on|off).
Unter Linux wurde das wie folgt getestet:
$ mosquitto_pub -h 10.23.42.31 -t "/room/light/3/command" -m "off"
$ mosquitto_pub -h 10.23.42.31 -t "/room/light/3/command" -m "on"
