Cloud-to-cloud THERMOSTAT DeviceTypeCheck failed

JSBP — Sat, 23 Aug 2025 10:30:39 GMT

Hi all,

Currently I am working on a Thermostat integration, I have to update the client secret for the account linking because it is expiring very very soon 😞 Unfortunately, the integration then has to be tested.

In the first step: "Check Device Types" - "Check the device type with Developer Console configuration." it fails directly with the error "DeviceTypeCheck failed: No bridge device is found in THERMOSTAT.: expected false to be true".

What does the error mean? In do not understand what goes wrong.

The thermostat doesn't use a bridge device, it is directly connected to wifi and internet.

How can I get this test passed?

I have already updated the "Device type" in the develop step to be only "Thermostat".

In the sync response I have the "deviceInfo" with manufacturer, model, hwversoin and swversion.

This is the only failing test, how to solve this?

Thanks for sharing. Can you please share the full sync response?
Also, double check that under Device Types section in Developer Console the configuration is set up to not require a bridge. You may need to deselect an option or modify a setting that specifies a dependency on a bridge.
After making these changes, save the new configuration and re-run the test.
