readTempSensorMockup starts by checking if there is an existing database file, according to the comments in the source code there should be a new file for each year. If there is no existing file it connects to the database and creates a new file/table. Once the creation has been made or if a file/table exists, a connection to MQTT is established which then fetches the JSON data from tempSensorMockup. Database connection is established and the JSON data is then added to the table by parameters in order to prevent SQL-injection. readTempSensorMockup has a 5 second delay between readings.

Activity diagram is not finished.

Everything is Mostly correct but, after Fetch Json data in the activity diagram there is a missing activity called e.g publish to mqtt due to "await mqttClient.PublishAsync(message); (line 76)".

Thanks for the review!
