Setup & gotchas

💡 Inside the US smart-home community, Lutron is the answer to 'I want lighting that just works for 10 years.' The Pro Bridge unlocks the local API; the standard Bridge does not.
🔗 Lutron exposes a stable local TELNET/LEAP API — Home Assistant, Hubitat, and openHAB all integrate it natively without cloud. That makes it a pragmatic 'closed-but-open-enough' choice.
