I have exactly the same problem as towsled On a Honeywell Lynx L5100 panel. I can see the status change in Indigo if I arm it locally, via the web or on the iOS App, but it will not arm via Indigo - and I am getting the same error messages in the Log and I can trigger a status update just fine.
Action Group Arm Stay
Honeywell TC2 Security Security panel Honeywell Alarm stay arming.
Honeywell TC2 Security Error Error in plugin execution ExecuteAction:
Traceback (most recent call last):

Ive been hoping to integrate this panel with Indigo for soooo long, so hope this is fixable - it looks like a great plugin if we can fix this issue
Thanks
