SmartApp
Event Handler SmartApps
Solution Module SmartApps
Service Manager SmartApps
Subscribe events and call a handler method
Built-in apps in dashboard
Be used to connect to your external devices
Device Type
Hub Connected Devices
Cloud Connected Devices
LAN-Connected Devices
ZigBee Home Automation Devices Z-Wave Devices
Authenticate via a standard OAuth2 flow Communicate via HTTP-based APIs
Communicate via REST or with SOAP requests using UPnP (Universal Plug and Play)
Device Type Handler
1. Event Subscription
2. Scheduled Events
3. Endpoint Triggers
SmartApp Execution
call a method at a particular time, e.g. runIn()
attribute changes -> creates an event (triggers a subscription, calls a handler method)
create an endpoint accessible over the web that calls a method within your SmartApp
