## Source excerpt

[This is article #6 in the Espressif Matter Series of articles. You may read the first part here.] In the previous articles we talked about Matter devices communicating with each other by themselves, or Matter devices participating in multiple ecosystems simultaneously. As you can see in the image here, this lightbulb is part of 2 distinct ecosystems, green and red. Each of these ecosystems don't know about the other, and they are powered by 2 separate organisations (Org1 and Org2).
