      I am trying to get direct access to the Digital In and the relays on the UniPi through Node-red. If I run an i2c scan I can see all the devices as specified in the hardware manual. I can connect I01-I06 & I11 through the rpi-gpio nodes, but no more. Any tips for disabling SPI to free up the other gpio ports? I havn't done the cabling mod for pins 13&14 yet but plan to.

      If I can interface with the hardware on the UniPi 1.1 directly I would prefer this as the only reason to use EVOK would be to get the inputs and outputs into Node-red... this would mean i'd skip all the EVOK stuff, less to reconfigure in the case of a hardware failure and less to go wrong software wise.

          @tomas_hora Thanks for the link but it doesn't explain why the gpio ports are unavailable when SPI is disabled. I used the raspi-config method.

            @sjp770 Ended up being a newer version of Node-Red was required.

            I2C relays are still a pain if anyone find a node based solution to those.
