I almost fell over reading this! This is a like a dream come true! Hopefully other manufactures (Are you listening CHAMBERLAIN!!!) will follow!

Now Supporting Matter: Seamless Smart Home Connectivity
What’s New:
Our 4th generation thermostats, S40 and L40 — now support Matter!
What is Matter?
Matter is a new universal smart home protocol that enables devices from different brands to work together seamlessly across platforms such as Apple Home, Google Home, and Amazon Alexa.
Why It Matters:
Matter compatibility allows our thermostats to integrate effortlessly with smart home platforms like Apple Home, Google Home, Amazon Alexa, and more — with no hubs or extra integrations required.
How It Works:
Users can view and adjust temperature settings directly from their preferred smart home app — without touching the thermostat. For full feature access, they can still use their thermostat or the Lennox Home App.
Unfortunately, they didn't provide any documentation on how to obtain a Matter pairing code. I'll have to go poke around to see if there's something on the thermostat to generate one.
