Four field notes, written to be read in order or dipped into. Start with the protocol if Matter is new to you; jump straight to the direction you care about if it isn’t. The plugin itself installs from the Indigo Plugin Store — the install guide picks up from there.
What is Matter
The protocol on its own terms — transports and Thread, border routers, commissioning, fabrics and multi-admin, and what “uncertified” actually means. No Indigo, no plugin mechanics.
№ 2 · Matter inThe controller
The share model: your ecosystem commissions the device, the plugin joins as a second admin over plain IP. What lands in Indigo, what has been validated on real hardware over Wi-Fi and Thread, and what to check when it doesn’t work.
№ 3 · Matter outThe bridge
Indigo devices published as one Matter bridge accessory — the opt-in allow-list, the roles you declare, pairing into an ecosystem, and an honest account of exactly what has and hasn’t been proven.
№ 4 · for the curious & plugin devsThe Proving Ground
How all of it is tested — the unit suites, the device zoo, a fifteen-device virtual Matter fleet, the bridge node’s own suite, and live validation on a production server.
