I've been mulling over the possibility of creating an Indigo plug-in that would effectively emulate an alarm system. Here's the background.
GlennNZ has been working on HomeKitLInk Siri for HomeKit integration into Indigo. One of the supported devices in HomeKit is a security system. Having a virtual security system plug-in in Indigo would allow HomeKitLink Siri to see the security system within HomeKit and allow Siri integration.
This virtual security system would expose four security alarm states: triggered, arm away, arm stay, and arm night. Then, within the Home app, one could create automations around these states.
Ideally this could be covered under an Indigo Virtual Device, but these can only have on/off states, and as noted above, this requires four states.
I would appreciate any feedback on this idea.
