summary: The LoRa gateway in the potting shed: where it hangs, what it publishes to, how it is checked

# LoRa gateway

Receives the readings from every `sensor-node.md` and publishes them to the broker.

- Where: potting shed, 2 m up, outdoor antenna. Power over Ethernet from the shed switch.
- Publishes to: `mqtt-broker.md`, topic `greenhouse/<house>/<node>/<metric>`.
- Health: `checks.md` pings it every minute; the inventory row is in `state.md`.
