BUILT WITH SEAM

From smart locks to thermostats. The Hospitable story.

“Once smart locks were solved, hosts began asking for thermostats to cut energy costs —so once again, we turned to Seam.”

Tim ParryProduct Manager, Hospitable

THE RESULTS

Seam’s April 2026 customer story described how Hospitable connected thermostats across brands in a matter of days. The story reported more than 1,000 connected thermostats shortly after launch.

A few lines of code. A more comfortable space.

Set a temperature, schedule a preset, hand control back, and keep your app in sync with webhooks.

Set a cooling target

Request a set point on a thermostat that supports cooling. Track the action result to confirm the setting.

1await seam.thermostats.cool({
2  device_id: "408641ab-d0f5-475c-b8a5-9b9096405f9a",
3  cooling_set_point_fahrenheit: 75,
4});

Create an occupied preset

Save a comfort range for a device that supports heat-cool mode, then activate it or schedule it for later.

1await seam.thermostats.createClimatePreset({
2  device_id: "ba9b816d-c255-46b9-a16d-971e6f535dd3",

6  hvac_mode_setting: "heat_cool",
7  cooling_set_point_celsius: 25,
8  heating_set_point_celsius: 20,
9});

Resume the thermostat’s schedule

Release Seam’s hold and resume the device’s existing weekly program. This keeps the current HVAC mode and does not reset or recreate the schedule.

Check that can_activate_weekly_program is true, then track the action attempt to completion. Available on compatible Honeywell Resideo, ecobee, and Sensi thermostats.

React to temperature events

Receive temperature changes and threshold alerts at your webhook endpoint. Update your app when conditions change or notify a property manager when a room gets too hot or cold.

Example webhook payloads. Configure a temperature threshold to receive threshold alerts.

NATIVE SCHEDULES

Make a change. Then hand control back.

Temporary adjustments should have an end. Release Seam’s hold on supported thermostats and resume the schedule already configured on the device.

Resume the thermostat’s current weekly program.
Keep its current HVAC mode.
Use Seam again when your next workflow starts.
