Since I never got the Fast(dot)com and Speedtest Sensors to work properly for me and I do have several Network Edge Points I like to monitor I created tis Docker Container with Fast(dot)com CLI sending data directly to an MQTT Broker.
You can then add the MQTT Data easily to Home Assistant or other Systems.
Maybe someone else finds this useful as well

This seems promising, but right out of the box I am seeing issues with mosquitto_pub and options being passed for publish. Anyone else experiencing similar issues?
Sending Data to MQTT (192.168.1.81:1883) - No Auth
Error: Unknown option '1.6'.
Use 'mosquitto_pub --help' to see usage.
Error: Unknown option '38'.
Use 'mosquitto_pub --help' to see usage.
Waiting for 3600 Seconds to continue...
The 1.6 and 38 are obviously the values from the results.
Resolved my issue. When installing via unRaid, there were additional docker variables that caused an MQTT-pub issue. Removing the unneeded variables, restart, resolved the issue.
