I have the same issue
Works for me.
Might be a problem with the PI-GPIO Module (https://github.com/rakeshpai/pi-gpio/) and newer Raspberry Models: https://github.com/rakeshpai/pi-gpio/pull/2
I have the first revision

Thank you for your feedback,
I will check the pi-gpio code maybe we will find a solution. I use Model B with 512MB RAM.
Off-topic: I modified the arduino code to read DHT22 sensors with success.
Thank you again.
I have installed the newest Raspian on my Raspberry to identify the problem, there might be some changes in the GPIO device. heimcontrol.js is looking in /sys/devices/virtual/gpio/gpio17/
, but this device does not exist in the new Raspian version.
{ [Error: ENOENT, open '/sys/devices/virtual/gpio/gpio17/value']
errno: 34,
code: 'ENOENT',

Look, what i find:
https://github.com/quick2wire/quick2wire-gpio-admin
we need to export the gpio pins...
I will try, and i will come back ...
Barni
After export, it's possible to set the direction in the gpio settings page, but in the main window does not sensing the state of the pin, it's always down. :(
I hope to help you with tis information.
Ok,
If i export with the following command:
gpio-admin export 22
and set in the settings panel in web interface PIN 15 -- INPUT
Everything is ok.
Ps. yesterday the export was with sudo gpio-admin export 22 ---> maybe this was the problem.
For mongopi stabilty improovement: turn on journalling for mongopi, because without jurnalling mongod deamon doas not start after power failure, or without proper shutdown.
I think the case is closed.
Thank you for your help.
I want to use the raspberry-s gpio port for reading inputs also, output its working great.
I want to see the state of the relays, even after system restart, and for this i wanted to use some of the gpio ports to see if it's on or off.
First of all I cannot set on the gpio settings page the direction to input, every tine when i hit save, it comes back to output.
I went to the database, and i changed there, from output to input, but alway i have the down state, even if i see with command line gpio readall the changing state.
Thank you.
