This guide walks you through connecting your Honeywell Resideo thermostats to Seam. Your thermostats must already be set up and working in the Resideo app before proceeding.

​
1. Create a Resideo account

If you don’t already have one, download the Resideo app and create an account. Add your Honeywell Resideo thermostats in the app and confirm they are online.

​
2. Connect Honeywell Resideo to Seam

Use the login credentials for your Resideo account to log in through the Seam Connect Webview and authorize Seam to access your devices.

​
3. Verify the connection

After completing the Connect Webview, confirm that your Honeywell Resideo thermostats appear in your Seam workspace and show an online status.

​
Troubleshooting

If your devices don’t appear after connecting:
  • Confirm that your Honeywell Resideo thermostats are online in the Resideo app.
  • Verify that you logged in with the same Resideo account that owns the thermostats.
  • Wait a few minutes for the initial sync to complete, then refresh your device list.
