Wens om 868MHz verzenden

Berichtdoor avdl72 » 19 apr 2014, 11:34

Hallo Nodo ontwikkelaars,

Ik ben benieuwd of er een Nodo komt die op 868MHz kan zenden en ontvangen?

Ik heb hier zonwering hangen die middels een Becker Centronic EasyControl EC545-II wordt bediend die in de buismotor is verwerkt, en ik geen mogelijkheid heb om er een KaKu module tussen te zetten.

De 868MHz Nodo zou dan via I2C verbonden kunne worden met de NES om zo toch toegankelijk te zijn vanuit de Webapp.
Volgens mij moet het dan theoretisch kunnen om het raw signaal op te pikken van de bediening en deze dan weer door de Nodo Webapp te laten versturen.

Als je gewoon een small pakt en de zender en ontvanger 868 maakt in plaats van 433 kan je misschien al wat ontvangen en versturen .

De frequentie is niet het enige probleem. Het protocol is veel lastiger. Heb je de originele afstandsbediening nog? Dan zou je het met een rawsignal misschien kunnen doen. Het makkelijkste is om een mega te pakken met daaraan 868MHz zender en ontvanger. Ethernet kaartje is nodig voor de sd card. Je zou dan de commando's kunnen inleren vanaf de afstandsbediening.

Ik heb uiteraard de afstandsbediening nog, dus die kan gebruikt worden om het originele signaal op te vangen.
Ik heb inmiddels wel gezien dat er AM en FM mogelijk is op 868MHz en ik heb niet kunnen achterhalen wat Becker gebruikt.

Ik merk aan de reacties dat er geen standaard oplossing is, en dat het zelf knutselen wordt om het misschien werkend te krijgen. En hier houd mijn electronica kennis ook op, wat het lastig maakt.
