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.

Based on Chamberlain's latest move, hell will freeze over before they open up Matter (or at least open up anything genuinely useful via Matter).

What did they do now?

I just bought several of the Konnected IO Blaq boxes during their sale. Now I need to climb up there an connect them. I'm sick and tired of the slow Chamberlain app with advertisements spread across across the top!

Released v3 security which will prevent RATGDO, Konnected, and other devices from working. This will come out on new openers, from what I understand not existing ones. Just to be safe I disabled internet access to my GDO after installing my RATGDO.

My advice is to velcro it beside the door button. I just pigtailed to the door button with short wires. No ladder, no moving the car out of the garage, and all that.

That also helps if you need to do an update on the Blaq, and it won't do an OTA update. You can either plug in your laptop at ground level, or you can easily remove it and do it in the warm/cool house.
