 ===== Testing and Next Steps =====
-==== To make it possible to post to AWS Broker set up topic for mqtt_pubslish as update and mqtt_get as get. (fix topic's names in WH register settings) ====
+==== Testing ====
 Okay, so now it is working AWS MQTT communication and tested successfully.
 The next step is to reconfigure MQTT topics from ''iot-test'' to Thing's Shadow ''.../update'' topic.

 ==== Setting up trigger script  ====
-There should be a trigger to change the register's value to post a message to AWS.  For the testing purpose you can do this manually.
+There should be a trigger to change the register's value to post a message to AWS, because of too short duration of scan and superfluity of update frequincy for cloud data processing.

+When you ensure, that data comes to DynamoDB triggered by auxilary WebHMI register change, you can set up the trigger's toggle by script.
 As an example there is two practices such as time dependent (oscillator) or quantity depended (decimation) trigger. \\

 If there is a neccesity to post with predefined frequency, for example 15 second can be done with following script.
 <code lua>
 a1,a2,a3,a4 = 0,0,0,0
