Die Temperatursensoren werden über einen JeeLink USB Stick empfangen. Der USB Stick ist als Serielles Gerät in Node Red eingebunden und empfängt die Signale der Temperatursensoren.
Die Konfiguration ist fix hinterlegt im ersten Node.
Die Sensorwerte werden mit dem Sensornamen als Topic angereichert und wenn ein gültiger Feuchtigkeitswert gemeldet wird, wird zusätzlich auch der Taupunkt berechnet und als JSON Daten an MQTT gesendet.
Wegen der Datenflut werden nur Änderungen gesendet. Zusätzlich wird alle 5 Minuten der aktuelle Wert ebenso gesendet, auch wenn dieser nicht geändert hat. Die . Man spart hierdurch beinahe 90% an Daten.
Hier ein Export des Flows:

Guten Tag, gibt es zu dem Thema noch weitere Infos zum Aufbau der Flows ? Leider sieht man ja nur den Inhalt der esrsten Config.
Liebe Grüße
Hallo,
Ich habe einen Export beigelegt. Dieser Flow ist nun schon einige Zeit aktiv und restartet Node Red zuverlässig wenn über 5 Minuten lang keine neuen Temperaturen rein kommen.
Ein Nachteil: Wenn man die Batterien wechselt muss man den Sensor neu konfigurieren.
Inzwischen stelle ich alles um auf Zigbee Mesh Netzwerk, da weit entfernte Technoline Sensoren (im Luftschutzkeller…) doch ab und an Verbindungsprobleme haben.
Vielen Lieben Dank, sie helfen mir damit ungemein weiter.
