Kamstrup M-bus in Home Assistant

[BiLLY_daKid]

Ok, ik ben een redelijke technoob, dus excuseer mijn gebrek aan juiste bewoording.


Ik zou graag de Multical 303 integreren in mijn HA systeem.

HA (met Mosquito ivm Heishamon) draait in een VMbox op een Windows nuc. De 303 is aangesloten op een USB-M-bus convertor en kon ik uitlezen met een tooltje.

Wat ik lees, is dat er eigenlijk altijd een raspberry tussen zit om de M-bus te vertalen naar MQTT telegrammen, en die weer door te zetten naar HA ? Of is het wel mogelijk om direct aan te sluiten?

[AUijtdehaag]

Waar zit de mbus adapter op aangesloten? Op je HA server?

Dan kan je node-red gebruiken
Kamstrup Multical 302 met Pi uitlezen en domoticz
Titel is wat verouderd, inmiddels zit ik al lang op HA

@AUijtdehaag Klopt, de M-bus adapter zit direct op de Nuc. Maar ik heb dus sowiezo een Pi nodig?

[AUijtdehaag]

Kun je geen node red installeren?

Geen pi nodig als hij in de NUC zit

Ik heb geen kennis van VMbox, dus ik weet niet of je de usb poorten ziet in HA?
