Samsung SmartThings and Apple HomeKit: How to Use Both Together
SmartThings and HomeKit can work in the same home. This guide covers the SmartThings HomeKit Bridge app, Matter Multi-Admin, and which SmartThings devices work natively with HomeKit.
SmartThings and HomeKit: The Official Integration
Samsung offers an official HomeKit integration through the SmartThings app. In SmartThings, go to Menu → Automations → SmartApps and look for the HomeKit Integration or HomeKit Bridge feature. This exposes all SmartThings-connected devices as a single HomeKit bridge, making them appear in the Home app as individual accessories.
This official bridge works for lights, switches, plugs, thermostats, and sensors connected to SmartThings. It requires a SmartThings Hub (V2 or V3) and the SmartThings app on an iOS device to complete the HomeKit pairing. Once set up, the SmartThings bridge appears in the Home app alongside directly-paired HomeKit devices.
Matter as the Better Long-Term Solution
The SmartThings HomeKit Bridge works, but it's a cloud-dependent integration that can have latency issues. A better approach for new devices is using Matter: SmartThings Hub V3 and the SmartThings Station support Matter and Thread, allowing Matter-certified devices to be controlled by both SmartThings and HomeKit via Multi-Admin.
For example, a Yale Assure Lock 2 (Matter) can be paired to SmartThings for advanced automation rules and also to HomeKit for Siri control and Home app access — completely independently, with both platforms having direct control of the physical device.
Devices That Work With Both
Many popular devices support both SmartThings and HomeKit natively: Philips Hue (via Hue Bridge), ecobee thermostats, Yale Assure Lock 2 (Matter), TP-Link Kasa EP25 (Matter), Aqara Hub M2 accessories, and Samsung SmartThings multipurpose and motion sensors (via the HomeKit Bridge).
Check HubMatch for any specific device — filter by SmartThings and HomeKit to see which devices work natively with both platforms without workarounds.
SmartThings-Exclusive Features
SmartThings has advanced automation capabilities that HomeKit doesn't offer natively: location presence without an iPhone (using SmartTags or other location devices), deeper Samsung appliance integration (washers, dryers, refrigerators), third-party Zigbee and Z-Wave devices that haven't been HomeKit-certified, and Samsung SmartThings Energy for monitoring whole-home energy usage.
For users with Samsung appliances, SmartThings remains the best automation layer. Adding HomeKit via the Bridge or Matter gives you Siri control and the polished Home app UI for everyday use, while SmartThings handles the complex multi-device automations in the background.
