Smart Thermostats & Climate Automation

Haven can connect to the smart thermostats you already own and switch the home to a comfortable occupied climate before check-in, then back to an energy-saving away setting at checkout. Guests can also adjust the temperature from the guide during their stay.

Thermostats use the same Seam connection as smart locks. Google Nest owners can also link their Google account to Haven directly — see Google Nest: connect directly.

Which thermostats work

Haven connects through Seam (the same stable catalog as smart locks). After you sign in, Haven syncs every device on that account that Seam reports as a thermostat. Haven does not keep a separate brand allowlist — if the device appears after Connect or Sync, Haven can write occupied and eco presets and schedule them around the stay.

Seam's API thermostat device types (common examples):

Brand	Seam device type
Google Nest	`nest_thermostat`
ecobee	`ecobee_thermostat`
Honeywell Resideo	`honeywell_resideo_thermostat`
Sensi	`sensi_thermostat`
tado	`tado_thermostat`
SmartThings	`smartthings_thermostat`

You do not need a separate Haven setup per brand. Heat, cool, or heat-cool depends on what that device reports (can_hvac_heat, can_hvac_cool, can_hvac_heat_cool). Setpoints are in Fahrenheit, 50–90 °F.

Locks on the same Seam account are set up separately — see Smart Locks. A PMS connection does not hide this section (unlike smart locks).

Connect and assign

Thermostats are set up per property, on the property's Edit Listing page. They need a paid Haven plan and a card on file. Your first month is free; after that each connected device costs $8/month at cost — the same as a smart lock. See Door Codes & Smart Locks for how the per-device charge works.

Open Edit Listing and go to the Smart thermostat section (search "thermostat" in the editor search bar).
Click Connect thermostat if you have not already linked a Seam account for locks. Sign in to your thermostat provider and return to Haven.
If locks are already connected, tap Sync — Nest, ecobee, Honeywell Resideo, Sensi, tado, and SmartThings devices on that account appear here.
Choose the device and click Assign to this property.

New assignments start at 70°F / 74°F for comfort and 60°F / 82°F for away, with comfort starting 1 hour before check-in and away starting at checkout.

Google Nest: connect directly

If the Smart thermostat section shows a Connect Google Nest directly button, you can link your Nest thermostats without Seam. Haven talks to Google's own Device Access API, so the connection is between your Google account and Haven only.

Click Connect Google Nest directly. You leave Haven for Google's partner-connection screen.
Sign in with the Google account that owns the thermostats in the Google Home app, tick the thermostats you want Haven to see, and allow access.
Google returns you to Haven. The thermostats appear in the device list with a Google Nest label; choose one and click Assign to this property.

Everything else works the same as a Seam thermostat: the same $8/month per device, the same comfort/away schedule relative to check-in and checkout, the same Set comfort / Set away tests, and the same Guest control in the web guide.

A few Nest-specific notes:

Nest thermostats speak Celsius; Haven converts your Fahrenheit setpoints and rounds to the nearest half degree, which is what the Nest app itself does.
Haven does not use the Nest Eco setting. At the end of a stay it sends your Away heat and cool numbers as ordinary setpoints, so what you enter here is exactly what the thermostat holds. If a guest (or you) had put the thermostat in Eco, Haven takes it out of Eco before applying comfort.
Google limits each thermostat to a handful of commands per minute. Haven sends at most three per change and spaces retries ten minutes apart, so a device that is offline or refusing commands does not get hammered.
If you remove Haven from your Google account (in the Google Home app, under Works with Google), the device shows reauthorization required in Settings → Smart Devices until you connect again. Devices Google stops returning drop out of the list and out of billing on the next sync.
Google requires the Google account to be a personal (gmail.com) account, not a Workspace account.

If you see No access to partner on Google's screen, Haven's Google integration is not yet approved for your account. Use the Seam connection meanwhile, or contact Haven support.

Climate schedule

Once assigned, Climate schedule is relative to this listing's check-in and checkout times. The clocks update if those times change.

Comfort starts — how long before check-in to warm or cool the home.
Comfort heat / cool — setpoints used during the stay.
Away starts — how long after checkout (or at checkout) to drop to the away setting.
Away heat / cool — setpoints when there is no stay.
Guest control — lets guests change the thermostat from the web guide during the stay (not yet in the native mobile app).

The guide shows guests a Thermostat tile on its Home tab from the time their arrival details unlock through the end of the stay. To keep the tile off the guide, turn off its switch under Edit Listing → Arrival → Guide layout & tabs (listed as Thermostat). The schedule still runs.

These save automatically. Heat or cool rows only appear when the device reports that mode.

Test the thermostat, sync, and remove

Set comfort / Set away — sends a real command to the assigned device using the temperatures currently on this page, so you can watch it change. This is not a dry run.
Test sync — pulls the latest device list and status from your provider. Use this after adding a new thermostat in your provider app. It does not change the temperature.
Remove thermostat — unassigns the device from the property. Haven stops scheduling climate for that property until you assign a thermostat again.

How it runs on a booking

For each confirmed reservation Haven:

Writes occupied and eco presets to the thermostat (Seam) or records the stay window (Google Nest direct).
Schedules occupied climate for the stay window (comfort start through away start). Seam runs that schedule on the device; for Google Nest, Haven sends the comfort setpoints when the window opens and the away setpoints when it closes.
Falls back to away at checkout, or immediately if the reservation is cancelled.

Troubleshooting

The thermostat doesn't change — open your thermostat app to check the device's status and connectivity, then click Set comfort or Set away on the Smart thermostat page.
No thermostats found — confirm the device is set up and online in your provider app, then click Sync.
