Quiet, scoped, exactly where it should be.
Only two MQTT brokers answer — calliope and mainsail. Both are Mainsail/Klipper hosts, which is the expected pattern. No stray brokers, no public exposure, no unauthenticated brokers on phones or cameras.
What's good
- MQTT footprint is minimal and predictable.
- Porchlight's own Home Assistant bridge talks to calliope's broker — that's the intended T2R6 path.
Worth a look
- Worth confirming the calliope and mainsail brokers require auth — Porchlight can't tell from a port scan alone.
