Application examples

Start from documented tasks and check the result at the receiving end.

Scale a sensor value

Convert a raw value of 255 into 25.5 °C and inspect the result before reporting.

Modbus to MQTT

Verify the instrument register first, then map its value and confirm the published message at an independent subscriber.

Avoid repeated alarms

Use the guide example of 30 °C alarm and 28 °C recovery. Report state changes rather than repeating the same alarm.

Detect missing data

The guide example detects 30 seconds without data and reports recovery when valid readings return.

Normalize LoRaWAN messages

Normalize already decoded fields, names and units. Raw radio payloads still need the correct device codec.

Expose fresh data

The read-only guide example returns HTTP 200 for fresh data and 503 when a value is missing or stale.
