  • tapping into Vaillant Ebus data

    From Harry Bloomfield Esq@21:1/5 to All on Sun Jan 26 14:10:21 2025
    I am completely clueless software wise, these days, but 40 years ago I
    could manage to get by....

    A few years ago, with a lot of help, I somehow managed to muddle through
    set up a Rpi, to log my weather stations data, which it still continues
    to do, to this day. It appears as neat values, and graphs, as a series
    of webpages, in cumulusmx.

    I now want to tap into the ebus data, of my Vaillant heating system, and control system. Towards this end, I have ordered a ebus, to wifi
    adaptor. One of these - https://www.elecrow.com/ebus-to-wifi-adapter-module-v5-2.html

    I'm fine with setting that up, configuring it to my LAN etc., just
    struggling with the next steps...

    It's been suggested I need a second Rpi, dedicated to the data
    collection from the ebus, something about installing ebusd on it, to
    translate the data, plus some higher level system, to display and
    collate the data? Home Assistant, or similar, but I don't need anything
    fancy, or difficult to set up, and many experts seem to struggle.

    Which of the many Rpi models do I need for this, what memory, and what
    sdcard please?

    Anyone able to explain to an idiot, and in simple terms, how to set it
    all up?

    A usefull extra, would be what I think might be called a mini-NAS. Just
    a USB stick plugged into one of the Rpi's, able to store files,
    accessible to any PC on my network..

    I can't help with those questions, but it might be worth trying in

    It's quite an active newsgroup so you should be able to get some help,
    see you there! :-)

    OK. It looks like that talks to a server running ebusd whatever that is


    It's been suggested I need a second Rpi, dedicated to the data
    collection from the ebus, something about installing ebusd on it, to translate the data, plus some higher level system, to display and
    collate the data? Home Assistant, or similar, but I don't need anything fancy, or difficult to set up, and many experts seem to struggle.

    Dont need a separate Pi. Juts install ebusd on whatever you have

    Which of the many Rpi models do I need for this, what memory, and what
    sdcard please?

    Anything from a [pi zero upwards will do
    Or what you have already

    Anyone able to explain to an idiot, and in simple terms, how to set it
    all up?

    Ebusd will probably write its data to a file.

    Mmm it appears you need to compile ebusd from source, on a Pi etc....
    I spent ten minutes and that was enough to say 'this will not be trivial'

    A usefull extra, would be what I think might be called a mini-NAS. Just
    a USB stick plugged into one of the Rpi's, able to store files,
    accessible to any PC on my network..

    Easy enough that one. Add the stick and export it over the network using
    SAMBA
