The team at https://buildwithmatter.com is doing a great job getting the word out and explaining Matter to a broader audience.
One webinar/podcast that stands out for me is a chat between Amir Pasdar and Sujata Neidig where they talk about some background stories and advanced topics around Matter.
In the talk, you will learn more about
- History of Project CHIP / Matter
- Comparison to other technologies
- How existing standards helped build the new Matter standard
- How the standard will evolve
- A lot of background around the alliance, the brand etc.
- How NXP helps manufacturers to adopt Matter
Very recommended if you already know a bit about Matter and you are still hungry for details!
