MQTT Sensor 提供的数据过多

Question

I have a setting with:

• MQTT temperature sensor
• Mosquitto broker
• Azure Cloud

The problem is that the sensor sends data every minute and there is no way to reduce these intervals to every 15 minutes (in Device).

Is there a possibility with the Mosquitto Broker to receive data only every 15 minutes or to forward the data to the cloud only every 15 minutes?

Thank you in advance

Answer 1

A real simple way to do this is to use Node-Red with an MQTT receiver node and connect it to a RateLimit node, setting it to 1 every 15 min. Modify the topic on the outbound send to something else and use that topic for the Azure Cloud.
