I deplyed it in my Raspberry Pi 5 using belana, but the graph didn't show any data. and When I checked speedtest service log in belana I found the following:

Hey @aboFaisal

It looks like Paho MQTT bumped by a major version which included some breaking changes: https://eclipse.dev/paho/files/paho.mqtt.python/html/changelog.html

And the version wasn't pinned in this project. I'll pin it to version 1.6.1 for now since I can't spot a super urgent reason to use the latest (i.e. no security issues) and the migration to 2.0 looks like it might take a while (PRs welcome).

I'm on it.

Pinning to 1.6.1 gets this project working again - so I'll PR that change now.
