The Honeywell Lyric integration integrates the Lyric thermostat platform into Home Assistant.

In Apple Home through HomeKit Bridge

What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.

Entity	Shows up as	Note
`climate`	Thermostat
`binary_sensor`	Sensor (motion, contact, leak, smoke…)
`sensor`	Sensor (humidity, temperature)
`select`	Mode picker (as switches)

2 reports below say how a device from this integration behaves in the Home app.

What people report

Cloud-only Honeywell Lyric thermostats work but users report repeated auth/unavailable problems; one user switched to the local HomeKit integration instead.

Honeywell Lyric thermostat (Fahrenheit display)	Partly works Cloud	Works in Home Half-degree setpoint does get set, visible in Home app	Half-degree Celsius setpoints round down in HA UI; value is set correctly on device Saved copy The problem When the Lyric thermostat (device) is set to display Degrees Fahrenheit, control in HomeAssistant (in Celsius) will round up or down to a whole degree Celsius.
