Connecting both combines the best of each approach.
Advanced Automation Examples
Once you've successfully integrated SmartThings with Home Assistant, you can create sophisticated automations that leverage capabilities of both platforms:
Whole-Home Movie Mode: When you activate "Movie Mode" through either system, it simultaneously dims Philips Hue lights (SmartThings), closes motorized blinds (Home Assistant), pauses robot vacuuming (SmartThings), and provides a notification confirming the scene activation (Home Assistant). This complex automation would be impossible with either platform alone.
Energy-Saving Routines: Monitor power consumption through SmartThings' integration with Samsung Smart Appliances, then use Home Assistant to trigger load-shifting automations. For example, when peak energy rates begin, automatically turn off non-essential devices and delay washing machine cycles until off-peak hours. This sophisticated cost optimization requires data from both platforms.
Occupancy-Based Climate Control: Combine SmartThings' mobile device presence detection with Home Assistant's local sensor data. When the last person leaves home (detected via SmartThings), Home Assistant activates eco-mode thermostat settings and adjusts smart vents. When the first person arrives home, SmartThings triggers a return-home routine that Home Assistant uses to set comfortable pre-arrival temperatures.
Smart Lighting Workflow: Motion sensors (SmartThings) trigger gradual light brightness increases (Home Assistant with zigbee lights) during evening hours, while daytime motion keeps lights at standard levels. When sunset occurs, SmartThings activates warm color temperatures on Philips Hue while Home Assistant simultaneously adjusts all other lighting. This seamless workflow requires bi-directional communication that the integration enables.
Laundry Notifications with Context: When the SmartThings washing machine reports cycle completion, Home Assistant checks current occupancy, room lighting, and time of day. It delivers notifications tailored to context-urgent audio alerts during work hours, gentle reminders in evenings, and automatic laundry room light activation for late-night cycles.
