Is the ISY a multitasking based device?
Yes. The ISY is running in a continuous loop(s) (multitask) doing a variety of things such as sensing user input, a button press somewhere, a web service request, and also sensing all the “state” changes on the network. Triggers are notified when there are changes in the state of the devices on the network and, based on the defined conditions, they perform tasks such as sending an sms/text/page, turning on/off a device/scene etc.
