Piface binding

My request might point in direction of a generic communication binding rather than making changes to the Piface binding. Let me know what you think.

I have been looking at Ben's excelent Piface binding, and came to the conclusion that it could do what I need for 95%. My usage is a Raspberry Pi without a Piface board. On my Raspberry I am using Pi4j to monitor pin 0.
Since it is the state of a smokedetector I need some sort of watchdog mechanism on the connection.
I have also ordered a DHT22 humidity sensor. It is not a Dallas 1-Wire sensor, so it needs its own pin and its own software. There are some samples on how to read out the sensor. For transmitting data from my Raspberry to OpenHAB I there need something more flexible than a byte. I need something that will fit values between 0 and 100.

I don't know if you think this points in a completely wrong direction of the Piface binding. I can argue for both that it does and also that it doesn't.

Please let me know if the above is possible to do in the piface binding or I have to start another binding?

Besides from having something that could values in the range 0 to 100, I completely forgot about the temperature part of DHT22. So a string would be nice....

I would suggest doing the DHT22 monitoring in a separate script (calling the software you mentioned) and use the openHAB REST API for sending data back. No need to complicate the PiFace binding for this I don't think.

The watch dog idea is a good one however, it has been on my TODO list for a while. I will hopefully get a chance to implement this soon.

Using the OpenHAB REST API for more complex data sounds like a great idea. I also like to keep stuff uncomplicated ;-)

Doing the watchdog would be fine.

Watchdog has been implemented and pushed to my fork ( https://github.com/sumnerboy12/openhab/commit/3b3e9fafc266436f8c818d64f4549bddf459bea9 ).
