Room sensor accessories (Honeywell Home RCHTSENSOR) paired to a T9/T10 thermostat are not being surfaced as entities

[clutch2sft]

The problem

Room sensor accessories (Honeywell Home RCHTSENSOR) paired to a T9/T10 thermostat
are not being surfaced as entities, despite the room data being present in the
raw API response the integration already receives, and despite this feature
being added in #104343.

The device page only shows 3 entities: the climate entity, "Indoor temperature",
and "Setpoint status". No Room Priority select entity is created, and no
per-sensor Room Temperature / Room Humidity sensor entities are created.

The Resideo mobile app shows the thermostat and all paired room sensors
correctly, confirming the sensors are live and paired on Honeywell's side.

Full lyric-related output from a clean setup (fresh OAuth re-auth, not just a
reload/restart of an existing entry). MAC address, device serial, internal
device ID, location ID, street address, and account username have been
redacted; all other fields are exactly as received.

What version of Home Assistant Core has the issue?

2026.7.2

What was the last working version of Home Assistant Core?

"Download diagnostics" option is available from either the integration page
or the device page.

Additional information

@dalinicus

Note the 'groups': [{'id': 0, 'name': 'default', 'rooms': [0, 1, 2, 3], 'groupOfGroups': []}]
field — this shows 4 paired rooms on this thermostat. Only one coordinator
(lyric_coordinator) is ever set up or run; no second coordinator, API call,
or platform setup for room accessories/priority is attempted, and no
errors are logged. The feature appears to silently no-op for this device
rather than fail visibly.

Additional information

Room sensor support was added in #104343 and is documented at
https://www.home-assistant.io/integrations/lyric/#selects, which states
it should be available "for T9 and T10 thermostats with at least one
paired room sensor." This device is model T9-T10 with 4 rooms present in
groups.rooms, so it should qualify per that description, but the
relevant select/sensor entities never materialize on either a config
entry reload or a full delete-and-reconfigure.

Following the request to verify uniqueness I did find:

Related but distinct from
#116668, where the priority API call is attempted and fails with a 400 for an unsupported (non-T9/T10) device. In this case, no priority/accessory call is attempted at all, despite the device being a supported T9-T10 model.
