 Most Speedtest.net servers require TCP port 8080 outbound to function. Without this port open you may experience significant delays or no results at all. See note on their [help page](https://www.speedtest.net/help).

 ## Integration Sensors
 
 The following sensors are added by the integration:
 
 sensors:
-  - Ping sensor: Reaction time in ms of your connection (how fast you get a response after you’ve sent out a request).
-  - Download sensor: The download speed (Mbit/s).
-  - Upload sensor: The upload speed (Mbit/s).

 ### Service
 
-Once loaded, the `speedtestdotnet` integration will expose a service (`speedtestdotnet.speedtest`) that can be called to run a Speedtest.net speed test on demand. This service takes no parameters. This can be useful if you have enabled manual mode.
