Unipi AND Energenie



  • Hi,
    I'm heading down the path to some home automation with my Unipi. as well as a hard wired solution with the Unipi, I have a requirement to operate a few Energenie sockets, and the controller for these requires to use the GPIO pins on the PI.

    My question is, is there any way for devices to "share" or "piggyback" each other on the same PI, or am I going to need to use multiple Raspberry Pi's to achieve this?

    This is what I was hoping to use: https://energenie4u.co.uk/catalogue/product/ENER002-2PI
    as well as the Unipi.

    Thanks.
    Merv.

  • Actually, the same question would be, what if I wanted to put a touch screen as part of my unipi solution? Many of the screens seem to use the GPIO pins, or at least a few of them.

  • I think it will work but you may loose some digital inputs - check the documentation of UniPi and the Energenie board which GPIOs colide and if/what are they used for at UniPi.

    Sharing GPIOs is not recommended.

  • If you have not bought already this, i would go with Razberry.

    It only uses RX/TX so will only loose UART ( serial ) and you will have much more devices to interface with Not only sockets



  • Thanks for the replies.

    It's what I expected, the gpio pins can only be used for one purpose. I'm happier now that I've confirmed that.

    The Zwave device looks nice, but I dont see how it can be used with a Unipi (which uses all 40 of the pins….).

  • As BlackSoll said, Razberry uses only the TX/RX pins. Those are wired out via the UART connector… So you can make a custom cable from the uart connector or even a custom cable between UniPi and RPi...
