Emerson Sensi HomeKit Thermostat features:

From across the room or across the country, your Emerson Sensi HomeKit thermostat makes it easy to remotely control and schedule your home comfort. Designed to work with the wires you already have, Sensi thermostat does not require a common wire (c-wire) for most installations, so it is compatible with the HVAC equipment in many homes. A c-wire is required for heat-only, cool-only and heat pump (without aux) systems, and for use with Apple homekit. Check compatibility on our website. The intuitive app walks you through each step of installation with custom configured instructions, removing all the frustration from the installation process so you can be up and running in no time, no experience required.
