 <\/p>\n
Grundkonfiguration PILIGHT:<\/span><\/h5>\n
sudo nano \/etc\/pilight\/config.json<\/pre>\n
hier werden folgende Einstellungen getroffen:<\/p>\n
{\r\n        \"devices\": {},\r\n        \"rules\": {},\r\n        \"gui\": {},\r\n        \"settings\": {\r\n                \"log-level\": 4,\r\n                \"pid-file\": \"\/var\/run\/pilight.pid\",\r\n                \"log-file\": \"\/var\/log\/pilight.log\",\r\n                \"send-repeats\": 10,\r\n                \"receive-repeats\": 1,\r\n                \"webserver-enable\": 1,\r\n                \"webserver-root\": \"\/usr\/local\/share\/pilight\/\",\r\n                \"webserver-port\": 5001,\r\n                \"webserver-cache\": 1,\r\n                \"firmware-update\": 0\r\n        },\r\n        \"hardware\": {\r\n                \"433gpio\": {\r\n                        \"sender\": 1,\r\n                        \"receiver\": 0<\/span><\/strong>\r\n                }\r\n        },\r\n        \"registry\": {\r\n                \"pilight\": {\r\n                        \"version\": {\r\n                                \"current\": \"5.0\"\r\n                        }\r\n                }\r\n        }\r\n<\/pre>\n
Die Einstellungen ,,sender“ und ,,receiver“ m\u00fcssen ge\u00e4ndert werden und an eure Pinbelegung angepasst werden.<\/p>\n
(0 entspricht Pin 11 und 1 entspricht PIN 12, laut WiringX<\/a> Pinbelegung)<\/p>\n
 <\/p>\n
Abfrage:<\/span><\/h5>\n
Um die Abfrage des Temperatursensors zu erm\u00f6glichen, habe ich ein \u00a0Script geschrieben, das nach der ID des Sensors (diese kann mit „pilight-receive<\/em>“ herausgefunden werden) filtert und die Ergebnisse dann in den Dateien „\/tmp\/Temperatur<\/strong>“ und „\/tmp\/HUM<\/strong>“ speichert.<\/p>\n
Abfragescript \u00a0(SHELL) Speicherort:“\/root\/auswerte“:<\/span><\/h6>\n
#!\/bin\/sh\r\ndienst=`ps -aux |grep pilight-receive|wc -l`\r\nif [ \"$dienst\" -le 1 ]\r\nthen\r\npilight-receive > \/tmp\/r-log 2>&1 &\r\necho Dienst wurde neu gestartet\r\nfi\r\n\r\nte=`cat \/tmp\/r-log |grep 1288 -a --text -C 2|tail -n2|awk '{ print $2; }'|sed 's\/,\/\/g'`\r\nTEMP=`echo $te |awk '{print $1}'` > \/tmp\/Temperatur\r\nHUM=`echo $te |awk '{print $2}'` >\/tmp\/HUM\r\n\r\n\/\/echo $TEMP\r\n\/\/echo $HUM\r\n\r\necho 0 > \/tmp\/r-log\r\n<\/pre>\n
 <\/p>\n
Das Script muss nun mit „chmod 777 \/root\/auswerte<\/em>“ ausf\u00fchrbar gemacht werden.<\/p>\n
Um das Script nun regelm\u00e4\u00dfig aus zu f\u00fchren muss ein cronjob angelegt werden.<\/p>\n
„crontab -r<\/em>“ zum anlegen des cronjobs:<\/span><\/h6>\n
*\/2 * * * * \/root\/auswerte\r\n<\/pre>\n
 <\/p>\n
<\/h5>\n
Die Ergebnisse werden nun alle 2 Minuten in\u00a0die beiden Dateien geschrieben.<\/p>\n","protected":false},"excerpt":{"rendered":"
