In the example illustration in Figure la the received signal strength indicator value RSSIv is illustrated at the Internet of Things device 20a and in the example illustration in Figure la the first wireless communication network connection lwcnc between the Internet of Things device 20a, 20b, 20c and the communication node 40 is also illustrated.
The processing circuitry 102a, 102b, 102c is configured to send, from the Internet of Things device 20a, 20b, 20c to the remote Internet of Things server 800 via the wireless communication node 40, a test request message via the first wireless communication network connection lwcnc, and receive, at the Internet of Things device 20a, 20b, 20c from the remote Internet of Things server 800 via the wireless communication node 40, a test response message via the first wireless communication network connection lwcnc, determine, based on the received test response message, at least any of a data transfer rate value TRv and a data transfer latency value TLv indicative of the Internet connection quality, and determine a quality of connection value QoCv, based on the obtained received signal strength indicator value RSSIv and at least any of the data transfer rate value TRv and the data transfer latency value TLv to determine if the quality of connection value QoCv is above a predefined threshold level.
According to some embodiments the connectivity performance test is initiated by the remote Internet of Things server 800. According to some embodiments the connectivity performance test is initiated by the Internet of Things device 20a, 20b, 20c. According to some embodiments the connectivity performance test is initiated by the electronic device 700. According to some embodiments the connectivity performance test is initiated by the electronic device 700 by input of a user of the electronic device 700.
An advantage with this first aspect is that the quality of connection value QoCv is used to verify that the Internet connection is a reliable Internet connection for a desired operation of the Internet of Things device 20a, 20b, 20c dependent on the received signal strength indicator value RSSIv and on and at least any of the data transfer rate value TRv and the data transfer latency TLv value to verify that the Internet connection is a reliable Internet connection according to the predefined threshold level.
A person installing the Internet of Things device 20a, 20b, 20c can hence confirm that the location where the Internet of Things device is installed is sufficient for the operation of the Internet of Things device. With reference to the example illustration Figure la, a user installing the Internet of Things device 20a, 20b, 20c can initiate the connectivity performance test from the electronic device 700. Before finalizing the installation of the Internet of Things device 20a, 20b, 20c the user can perform the connectivity performance test to verify a reliable Internet connection for an Internet of Things device 20a, 20b, 20c.
According to some embodiments the quality of connection value QoCv can be expressed as a function of the received signal strength indicator value RSSIv, the data transfer rate value TRv and the data transfer latency value TLv:
QoCv = f (RSSIv + TRv + TLv)

According to some embodiments the quality of connection value QoCv is dependent on that the received signal strength indicator value RSSIv is above a predefined threshold level.
In an example, a too low received signal strength indicator value RSSIv may not be accepted due to the risk that there is an interruption from time to time if the Internet connection.
According to some embodiments the quality of connection value QoCv is dependent on that the data transfer rate value TRv is above a predefined threshold level. In an example measuring the surrounding temperature may require a very low data transfer rate, while for example transferring high resolution live streaming video may require a very high data transfer rate value TRv.
According to some embodiments the quality of connection value QoCv is dependent on that the data transfer latency value TLv is above a predefined threshold level. In an example in a door operation control system, interrupt opening or closing of a door must occur instantly, while checking the light condition at the door must not occur instantly.
According to some embodiments the quality of connection value QoCv is continuously determined at a predetermined frequency to determine if the quality of connection value QoCv falls below the predefined threshold level.
An advantage with this embodiment is that the Internet connection can be verified as a reliable Internet connection for an Internet of Things device 20a, 20b, 20c over time as long as the quality of connection value QoCv is above the predefined threshold level which gives comfort in the operation of the Internet of Things device 20a, 20b, 20c over time.
