Click the link below to view the Honeywell Lyric thermostat data sheet. Keep in mind this Lyric thermostat data sheet is for the older generation 1 thermostat but, everything will remain the same and can be applied to the newer generation 2 lyric thermostat.
The only thing you will have to keep in mind is that the generation one lyric thermostat will not be compatible with Apple HomeKit or Siri voice functions as generation 2 will be.
The Lyric thermostat is not just a standalone Wi-Fi thermostat Honeywell has developed a whole wireless connected platform around the thermostat. The Lyric wireless connected platform includes a whole line of encrypted security products and at the front line of the Lyric security system is the Lyric Controller. The Honeywell Lyric controller is the main control panel for both security and home automation features and has built upon many years of Honeywell wireless professional security systems.

To clarify a common question the Honeywell Lyric security system doesn't utilize the Lyric App it uses a different application and its called Total Connect 2.0. You may be thinking that is a bit confusing so I will simply.
Total connect 2.0 is for control of your security and home automation features including basic functionality of your Lyric thermostat. But, as far as being able to use Siri and Apple HomeKit this will only apply to your Lyric thermostat. For example: You can't ask Siri to arm or disarm your security system you will only be able to control features of the Lyric thermostat specifically from Siri.
The reason why is because Apple HomeKit and Siri are only able to connect to the Lyric app. So in conclusion, You are able to integrate the Lyric thermostat into the Lyric security system and be able to control and setup smart scenes through total connect 2.0. But, if you want to control your Lyric thermostat via voice commands through Apple HomeKit and Siri this will be done through the Lyric app.
At the end of the day you are able to have the best of both worlds still because both the Lyric App and Total Connect 2.0 can exist together to provide you with all the functionality.
