 ===== Configure WebHMI =====
-There is a [[iot#webhmi_as_mqtt_publisher_client|WebHMI as MQTT Client]] considered [[iot|here]]. The only difference is the Broker's settings, that time you need to connect to AWS and identification is related to certificates also.

-Be sure that your bunch of certificate files are valid and binded to your Thing in AWS, to [[aws-integration#test_connection_via_pc_client|test it using MQTT.fx]] is highly recommended.
+Be sure that your bunch of certificate files are valid and binded to your Thing in AWS, to [[iot:tutorial:aws-integration#test_connection_via_pc_client|test it using MQTT.fx]] is highly recommended.
 The first thing is to create connection to AWS MQTT Broker. Click at "New connection".

 Firstly select the "Device model: MQTT".
 Fill in the "Device address" from IoT Core [[http://docs.webhmi.com.ua/_media/wiki:iot:aws:shadow:aws_console_iot_interact_topics.png|Interact]] menu and 8883 port accoiding to [[https://docs.aws.amazon.com/iot/latest/developerguide/protocols.html|AWS Developer Guide]]

 Go to MQTT tab to copypaste certificates to WebHMI connection settings.
 At the moment you should configure MQTT.fx to work with AWS IoT Core Thing's Shadow. So, you have all files downloaded such as .pem and .crt.

 Pick the **TSL version v1.2** at the final.

 Now, there is a connection configured. Let's create a register which would correspond to MQTT topic. \\

-So to test the connection, let's act WebHMI as subscriber and act MQTT.fx as publisher and vice versa to see the both of clients works well.

-For know, it is WebHMI can post the data from real devices to various AWS Things, visualise with QuickSight tool and store this data in DynamoDB with possibility to import as .csv file to S3 bucket for example.

-==== JSON formatted payload ====
-It is widely used MQTT payload format JSON.
-Let’s write a small script which will use inbuild library to encode any WebHMI register values to JSON formatted strings.
-Here is the code example to encode a string type message with Amazon Web Services (AWS) [[https://docs.aws.amazon.com/iot/latest/developerguide/device-shadow-document-syntax.html|Thing Report Shadow]] JSON format.
-<code lua - AWS_thing_report.lua>
-function main (userId)
-    local decoded =
-    {
-    state =
-        {
-        reported =
-            {
-            timestamp       =   os.date("%Y-%m-%dT%H:%M:%S", os.time() - 3 * 60 * 60),
-            message         =   "Hello, WebHMI!"
-            }
-        }
-    }
-    encoded = cjson.encode( decoded )
-                                        DEBUG(encoded)
-    WriteReg("mqtt_publish", encoded); -- Test Publish (iot-test@MQTT WebHMI Client)
-end
-</code>
-To check the result of script work let’s check “iot-test” subscribed topic in MQTT.fx.
