Had a quick search regarding iButtons on this forum and it indicates they might be supported, however I am struggling to find out which UCM etc I would need.

They run using the 1-Wire protocol???

Any ideas?? Would be looking to use this as an alternate method of disarming Comfort.

iButtons seems like a good idea but I am not sure ir
  1. people would like to carry it around, especially women
  2. The methods of presenting the ibutton to a reader are practical, ie it must make contact to something which can read it
These seem to be more suitable for an industrial or office /access control



Do you have any ideas in mind?

It sounds like my project :-)

I designed a RIO module for Comfort that reads 4 x 1-wire temperature sensors and updates Comfort Counters|Sensors with values read. I am sure a different type of device can be added but it would require some code changes to handle whatever it needs to do. It's currently in Beta phase with Chiu and Julian being the lucky ones that are going to toy around with it.

The current model 1.0 of my 'Arduino RIO' doesn't have much code space left and it might not be able to handle any further development. Perhaps I will upgrade the cpu to something bigger like a M0 processor but it's too early to tell.

The thought process behind this was as follows ......

Elderly relatives can use iButton as opposed to trying to enter code on small keypad (KP06 in my case)

Each user can have their own iButton to identify themselves (same as individual codes)

Can use magnetic iButton reader as place to keep keys. User presents iButton to reader (disarms alarm). When they leave the house, grab keys from reader and Comfort starts arming

Finally for the Geeks. 2-factor authentication. User needs passcode (something you know) and present iButton to reader (something you have) to disarm alarm.

From what I understand, the iButton presents a unique string of data (that could be stored the same way Comfort stores IR codes?) in order to identify itself

Anyone could take the keys from the reader and he would be able to disarm it any time. Isnt that a risk?

My situation is residential. If they took my keys, they would also have my car! Just as if they were on the worktop.

All my family are able to disarm the system - This option would suit a particular scenario.

Would also need a system to cancel arm if not the last occupant, however in this instance you just wouldn't, dock your keys (the electronics would take care of the two methods)

Hi,

I integrated iButton for easy arming/disarming at the front door. The button is connected to a door switch which temporarily activates a switch. Lost or stolen buttons can easily be deactivated. This switch is connected to my Comfort input as DigitalNC zone type and a OnResponse of the following:

If SecurityMode = SecurityOff And AlarmState < Alert Then
KeyswitchArm AwayMode
Else
KeyswitchArm SecurityOff
End If

Works like a charm!

Cool....Do you have a link to the iButton module you are using?? I am guessing this takes care of the enrolment etc of new 'buttons'?
