Question:
MQTT topic transform in Mosquitto
Description:
I'm working on integrating a Shelly sensor(https://shelly.cloud/) into an existed IoT system FIWARE(https://www.fiware.org/). The sensor can publish the monitoring data via MQTT with JSON payload.
Shelly sensor published the data at topic
{SHELLY_ID}
/events/rpc, but the FIWARE can only subscribe on topic /json/api-key/device-id/attrs. The topic of publication and subscription are different now. In our application, we use Mosquitto as an MQTT broker, is it possible to do the topic transform in Mosquitto broker?
I think Mosquitto has full knowledge of topics and can do the topic mapping and transformation easily. Does anyone have an idea or information for this? I think it's much easier than to re-build and customize the FIWARE system.
