I am developing a Matter thermostat device and would like to understand the specific requirements for supporting the Adaptive Temperature feature in the Apple Home app.

What we have tested:

We built a standard Matter 1.4 thermostat that implements the Thermostat cluster with support for Cool, Heat, and Auto modes. We successfully added this device to a HomePod running iOS 26.2 (or later). However, the Adaptive Temperature button does not appear in the device settings within the Home app.

Our questions:

Are there additional Matter cluster attributes or features beyond the standard Matter 1.4 Thermostat cluster that are required for Adaptive Temperature to be recognized by Apple Home?

Does Adaptive Temperature require any specific device type or optional feature (e.g., occupancy sensing, local temperature reporting intervals, or support for Auto mode in a particular way)?

Is there any special entitlement or capability that must be enabled in the Apple Developer account (e.g., under Certificates, Identifiers & Profiles) for a Matter device to expose Adaptive Temperature?

Are there known reference implementations or test cases we can follow to validate Adaptive Temperature support?

Any documentation, technical specifications, or guidance would be greatly appreciated.

Thank you.

At this point, we haven't published any guidance on Matter thermostat support. Can you file a bug on this and then post the bug number back here? I'd like to discuss this with the team to see what information I can provide; however, I also need a bug to document this as a formal request. As part of that bug, I'd also appreciate any additional information you can provide about your product (vendor, general product plan, etc.). Once you post the bug number back here, I'll follow up with the team and see what I can find out.

However, one small comment here:

Is there any special entitlement or capability that must be enabled in the Apple Developer account (e.g., under Certificates, Identifiers & Profiles) for a Matter device to expose Adaptive Temperature?

No, I don't think anything like that is involved. Generally speaking, none of Home.app's accessory support REQUIRES[1] a vendor-specific app to be installed or "involved".

[1] The only exception I can think of are smart locks, which often require a vendor-specific app to be involved for initial setup and management.
