@Homoran Um das ganze nochmal abzuschließen.

ja es ist Signed16BE, trotz dessen, dass es 4 Stellig ist. Bei 32 hatte ich das Problem, dass 2 Werte zusammen genommen wurden.

Modbus Adapter per Ethernet hat heut auch geklappt.

Als nächstes kommen noch meine weiteren Boards dran, dann kann ich endlich sehen, was meine Fußbodenheizung so macht. Wenn ich es von meinem Brettaufbau verteilt fest eingebaut habe

(In jeden Verteiler kommt ein Board mich bis zu 8 Sensoren, und im Keller direkt an der Heizung auch an den Vor/Rücklauf.)

Insgesamt hat mich das nun keine 100€ gekostet. Alternative und sicher einfacher wäre alles in KNX gewesen, aber preislich ist as über Modbus und den günstigen Sensoren kein Vergleich.

@homoran
Naja, wenn man das lesen kann... Aber vielen Dank dir, für deine Unterstützung nun läuft es.

nächster Schritt, schauen, was passiert, wenn's über 25,5°C wird (Länge 1 = FF = 25,5°C)
übernächster Schritt, alles über ModBus to ETH Adapter.

Das alles aber erst, wenn ich wieder Zeit dafür hab.
Vielen Dank nochmal und einen schönen Abend noch!

Es tut :

jetzt nur noch die Werte mit 0,1 multiplizieren und es ist erledigt

wir kommen voran! die 12714179°C aktualisieren sich alle ~1 sekunde (alle 1 Sekunde wird der Wert tatsächlich gesendet, daher ist die Polltime quatsch, ABER!!!! es kommt was an)
Jetzt muss man das nur noch in 8 verschiedene Temperaturwerte aufdröseln, entsprechend umwandeln, dann hätten wir es schon.

12714179 in Hex sind C2 00 C3 und scheint die Antwort auf die Anfrage davor zu sein.

Hab alles andere raus.
Int16be hat aber nur eine Länge von 1, ich brauche aber eine Länge von 2. Der Temperaturwert sieht dann wie folgt aus: erste Ziffer 0 = +, 1=-. Rest ist Hex, muss in's Dec und *0,1. Gibt es dafür einen geeigneten Typ?

da ist kein usb port eingetragen
müsste auch im log zu sehen sein.

Danke, hab ich übersehen:
Nun korrigiert:

Im Log sieht's gerade so aus:

Hier noch, was gerade auf dem Modbus läuft:

wie kommst du daran?
Zwei Zugriffe auf den selben USB gehen nicht!

Ich hab am selben Modbus den USB Converter, auf den nur der ioBroker Zugriff hat, außerdem hängt noch der Modbus to ETH Adapter drin, der im Moment einfach mitliest. Das mitlesen kann ich mir dann im SBSCOM anzeigen lassen. So weiß ich auch, dass die Adresse stimmt und auch die Baudrate richtig eingestellt ist.

Wie kommst du auf 32 Bit Unsigned?
Hab ich nichts in der Anleitung gefundrn

Ich hab bisher auch nur beim Eingangsregister etwa eingetragen, alles andere ist bisher leer. Ist das überhaupt das richtige? Kann ich darüber überhaupt mehrere Werte aus einer Nachricht auslesen?
