Why we use MQTT over HTTP for IoT end Devices -

- MQTT actually saves a lot of data. It’s super lightweight, the message header is like 2 bytes only, where HTTP sends a bunch of big text headers every time. So it costs less data and works way better on slow or unstable network.

- MQTT gives instant updates because it works on a push system. The moment new data is ready, server pushes it to your device. But with HTTP you always have to keep asking the server (polling), which is slow and kind of waste data and processing.

- For battery devices, MQTT is honestly a life saver. Since it’s not polling all the time and sending small packets, the device can sleep more and battery last way longer.

- Another big thing is reliability on unstable network. MQTT has QoS levels that make sure your message delivered even if the network dropped for a second. And the “Last Will” thing is awesome — the system knows immediately if your device went offline or crashed.
