Meshtastic Sensor Broadcaster

Periodically reads selected Home Assistant sensors and broadcasts them as a single short text message to a Meshtastic channel.

Options

Option	Description
connection	tcp (node on the network) or serial (node on USB).
host	Node IP/hostname (TCP mode).
serial_port	Device path, e.g. /dev/ttyUSB0 (serial mode).
channel_index	Meshtastic channel index. 0 = primary.
interval	Seconds between broadcasts.
prefix	Optional text/emoji prepended to each message.
sensors	List of {label, entity_id, unit} to include.

Example message: 🏠 T:21.4°C H:48% P:1013hPa

Airtime

Keep messages short and the interval reasonable (>= a few minutes) to stay within LoRa duty-cycle limits and avoid congesting the mesh. Unavailable sensors are skipped automatically.

Serial nodes

Set connection: serial and serial_port to your device. The add-on requests uart/usb access; check the device path under Settings -> System -> Hardware.
