Announcing SmartThings-Connected Thermostats Support

Announcing SmartThings-Connected Thermostats Support

This week, we’re excited to announce a new facet of our SmartThings integration. We already supported SmartThings-connected smart locks, and now we’ve added support for thermostats connected to SmartThings Hubs. Because SmartThings acts as a bridge to Z-Wave thermostats, expanding our integration support to SmartThings-connected thermostats gives you access to a broader range of hardware without limiting connectivity to Wi-Fi-only devices.

Our expanded SmartThings integration means that you can now gain control over thermostats from providers for which we haven’t yet built native integrations. Think of the possibilities: If it works with SmartThings, it works with Seam!

Getting Started

Are you already running SmartThings in your Seam workspace? If so, there’s no need to rebuild. Just connect new thermostats, and you’re ready to go! See our getting started guide.

2025.06.06 Changelog

New

• Credential creation through user identities: To simplify the credential creation flow, we’ve eliminated the need to create an ACS user explicitly. When you work with credentials, access groups, and so on, you can specify the user identity and ACS system, and Seam now creates a corresponding ACS user automatically and links it to the user identity. For an example, see our mobile key quick start.
• Sync devices on demand: We’ve added a new endpoint to enable you to sync a connected account’s devices manually as a fallback mechanism. Use /connected_accounts/sync and specify the connected_account_id of the account that you want to sync.

Changed

• Speedier phone registrations: We sped up key steps within the mobile credential creation process. We’ve cut down the amount of time from issuing a mobile key to your guest unlocking their door to mere seconds.
• Improved Honeywell available HVAC modes detection: We improved the accuracy of our available HVAC modes detection for Honeywell Resideo devices.
• Salto KS OAuth support: We changed the authentication mechanism for our Salto KS lock integration to use the industry-standard OAuth for improved privacy and security. To connect any new Salto KS accounts to Seam, use the salto_ks provider key. For instructions, see Customize the Brands to Display in Your Connect Webviews.
