+ | <b>Why MQTT-flex</b> <br> | ||
There is a lot of approaches in integration of MQTT in devices and systems. One vendor prefer one topic with structured data payload, the another one prefer tree topic structure with simple value in data payload. MQTT-flex is a standard [https://en.wikipedia.org/wiki/MQTT MQTT] with specific configuration approach. The goal of MQTT-flex is to give a user opportunity to integrate NETIO device with any system with different data approach. | There is a lot of approaches in integration of MQTT in devices and systems.

Configuration of MQTT in devices supporting <i>MQTT flex</i> is done by [https://en.wikipedia.org/wiki/JSON JSON (JavaScript Object Notation)]. With MQTT-flex you can easily define the MQTT topics, payloads and device behaviour via text configuration in JSON object format. Since there is then lot of possibilities with such freestyle flexibility allowed, you can find bellow full set of all implemented attributes. | Configuration of MQTT in devices supporting <i>MQTT flex</i> is done by [https://en.wikipedia.org/wiki/JSON JSON (JavaScript Object Notation)].

+ | ''We strongly recommend to create and test MQTT-flex configuration on "local" device what can be easily restarted. The validation of config before saving is not 100% and for example some specific typos can cause a freeze of a device - the solution is to restart a device (unplug/plug input power cable). If the configuration is saved and device is working then there are no known failure case so it is safe to use this configuration on the "remote" devices.'' | ||

+ | This example show Request response implementation in MQTT and toggle action made by Rules. | ||
+ | |||
+ | When message with payload <code>getValues</code> is published to topic <code>broker/gv90018g/COMMAND</code> MQTT flex will create an event with name <code>PROTOCOLS/MQTT/EVENT</code> (fixed name cannot be changed) and value <code>getValues</code>. On this event will act all events and conditions set in MQTT-flex and Rules which are set to listening to change on <code>PROTOCOLS/MQTT/EVENT</code> and equals to value <code>getValues</code>. See <b>bold</b> marked parameters in example configuration below. | ||
+ | |||
+ | Once the triggered action is done it is needed to reset MQTT channel to <code>OK</code> status becaus event are reacting only to change. If the channel is not reset the next even would not be triggered. | ||

The MQTT-flex version of the MQTT protocol can be configured in detail thanks to the “flex” extension.
https://www.netio-products.com/en/glossary/mqtt-flex
Why MQTT-flex
There is a lot of approaches in integration of MQTT in devices and systems. One vendor prefer one topic with structured data payload, the another one prefer tree topic structure with simple value in data payload. MQTT-flex is a standard MQTT with specific configuration approach. The goal of MQTT-flex is to give a user opportunity to integrate NETIO device with any system with different data approach.
Configuration of MQTT in devices supporting MQTT flex is done by JSON (JavaScript Object Notation). With MQTT-flex you can easily define the MQTT topics, payloads and device behaviour via text configuration in JSON object format. Since there is then lot of possibilities with such freestyle flexibility allowed, you can find bellow full set of all implemented attributes.

Simple MQTT-flex configuration + explanation
We strongly recommend to create and test MQTT-flex configuration on "local" device what can be easily restarted. The validation of config before saving is not 100% and for example some specific typos can cause a freeze of a device - the solution is to restart a device (unplug/plug input power cable). If the configuration is saved and device is working then there are no known failure case so it is safe to use this configuration on the "remote" devices.
{ "config":{ "broker":{ "url":"broker.hivemq.com", "protocol":"mqtt", "port":1883, "ssl":false, "type":"generic", "username":"freedom", "password":"peace|LOVE|empathy4ALL" }, "subscribe":[{ "topic":"netio/${DEVICE_NAME}/output/1/action", "qos":0, "target":"OUTPUTS/1/ACTION", "action":"${payload}" } ], "publish":[{ "topic":"netio/${DEVICE_NAME}/output/1/state", "qos":0, "retain":false, "payload":"${OUTPUTS/1/STATE}", "events":[ { "type":"timer", "period":"1000" } ] } ] } }
Client Configuration (broker section)
Put here MQTT client connection setup
This configuration example set NETIO device to connect to broker.hivemq.com with mqtt protocol, no ssl connection with credetials freedom/peace|love|empathy4ALL.
"broker":{ "url":"broker.hivemq.com", "protocol":"mqtt", "port":1883, "ssl":false, "type":"generic", "username":"freedom", "password":"peace|LOVE|empathy4ALL" },
Device Control (subscribe section)
Put here array of topics where to subscribe
Device output 1 is controlled with action received by subscription to netio/${DEVICE_NAME}/output/1/action topic with QOS 0
"subscribe":[{ "topic":"netio/${DEVICE_NAME}/output/1/action", "qos":0, "target":"OUTPUTS/1/ACTION", "action":"${payload}" } ],
Output State monitoring (publish section)
Put here array of topics where to publish.
Device send every 1000 s message to topic with QOS 0, retain true information with output 1 state
"publish":[{ "topic":"netio/${DEVICE_NAME}/output/1/state", "qos":0, "retain":true, "payload":"${OUTPUTS/1/STATE}", "events":[ { "type":"timer", "period":"1000" } ] } ]
Config sections
Broker
here you have to define URL or IP address of machine hosting MQTT broker, level of security used for protocol, auth data and optionally some specific MQTT attributes, which are in the spec, but not mandatory required
Attributes table overview
Item | Presence | Possible Values | Description | JSON Config Usage |
---|---|---|---|---|
url | mandatory | MQTT broker URL | "url":"broker.hivemq.com" | |
port | mandatory | 1 - 65535 | MQTT broker port | "port":1883 |
protocol | mandatory | protocol spec - mqtt | "protocol": "mqtt" | |
ssl | mandatory | true, false | Use SSL crypted communication selector | "ssl":false |
type | mandatory | generic | Communication/setup type option | "type":"generic" |
username | mandatory | regexp+len | Credentials for MQTT broker. Max. 128 characters (since FW 3.2.4). | "username":"freedom" |
password | mandatory | regexp+len | Credentials for MQTT broker. Max. 256 characters (since FW 3.2.4). | "password":"peace|LOVE|empathy4ALL" |
clientid | optional | regexp+len | MQTT clientid. Max. 128 characters (since FW 3.2.4). Variables ${DEVICE_MAC} or ${DEVICE_NAME} can be used | "clientid":"myEcoTable01" |
keepalive | optional | 1 - 65535 | MQTT keep alive period in seconds | "keepalive":90 |
Note 1: clientid attribute is mandatory for MQTT(s) communication. When not configured, random ID will be generated.
Note 2: To proper communication with MS Azure - it is necessary to set up IoT Hub to use TLS 1.2
See section "TLS 1.2 enforcement available in select regions" in following guidelines https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-tls-support
Examples
Standard setup
Security (SSL / TLS) secured setup
You can enable MQTTs by using the encrypted port 8883 + "ssl":true.
Variables used setup
Subscribe
Hints to usage
When receive message in topic do action on target.
actiondef: When message in topic match actiondef payload do action on target.
Attributes table overview
Item | Presence | Possible Values | Description | JSON Config Usage |
---|---|---|---|---|
topic | mandatory | see table below | specification of the topic, which MQTT-flex device listens from broker and act accordingly. Max. 128 characters. The "#" can be used since FW 3.2.4 - see note under this table. | "topic":"netio/${DEVICE_NAME}/output/1/action" |
qos | mandatory | 0, 1 or 2 | MQTT's Quality of Sevice - definition {here|http://docs.oasis-open.org/mqtt/mqtt/v3.1.1/errata01/os/mqtt-v3.1.1-errata01-os-complete.html#_Toc442180912} | "qos":0 |
target | mandatory | internal definition of action, which can be performed above the specified output | "target":"OUTPUTS/1/ACTION" | |
action | mandatory | a payload or a value the action attribute needs to have passed to | "action":"${payload}" | |
actiondefNot supported yet | optional | |||
jsonNot supported yet | optional |
Note: The "#" wildcard can be used in subscribe topic definition. The multi-level wildcard character MUST be specified either on its own or following a topic level separator. In either case it MUST be the last character specified in the Topic.
For example, if a Device subscribes to “devices/{device_id}/messages/devicebound/#”, it would receive messages published using these topic names:
“devices/{device_id}/messages/devicebound/”
“devices/{device_id}/messages/devicebound/{property_bag}”
This should be usefull for use with MS Azure - IoT hub.
MQTT Subscribe as event to trigger action FW 4.0.0+
This feature allow to subscribe to specific MQTT topic and pass payload to Rules or MQTT-flex as event.
target: PROTOCOLS/MQTT/EVENT
"subscribe": [ { "action": "${payload}", "qos": 0, "target": "PROTOCOLS/MQTT/EVENT", "topic": "broker/12345/MQTT_EVENT/" } ]
Examples
Toggle output with standard payload
Toggle output with custom payload
Subscribe to more than one topic
Trigger Rule and MQTT publish from MQTT subscribe FW 4.0.0+
This example show Request response implementation in MQTT and toggle action made by Rules.
When message with payload getValues
is published to topic broker/gv90018g/COMMAND
MQTT flex will create an event with name PROTOCOLS/MQTT/EVENT
(fixed name cannot be changed) and value getValues
. On this event will act all events and conditions set in MQTT-flex and Rules which are set to listening to change on PROTOCOLS/MQTT/EVENT
and equals to value getValues
. See bold marked parameters in example configuration below.
Once the triggered action is done it is needed to reset MQTT channel to OK
status becaus event are reacting only to change. If the channel is not reset the next even would not be triggered.
Rules Configuration:
{ "conditions": { "PROTOCOLS/MQTT/EVENT": "getValues" }, "actions": { "OUTPUTS/1/ACTION": 4 } }
MQTT Configuration:
{ "broker":{ "clientid":"netio${DEVICE_SN}", "keepalive":30, "password":"abcdefghijk", "port":8883, "protocol":"mqtt", "ssl":true, "type":"generic", "url":"broker.cloud.netio.eu", "username":"gv90018g" }, "groupEvents":[ { "events":[ { "source":"PROTOCOLS/MQTT/EVENT", "type":"change", "value":"getValues" } ], "appliedTopics":[ "broker/gv90018g/OUTPUTS/1/STATE", "broker/gv90018g/COMMAND" ] } ], "publish":[ { "payload":"${OUTPUTS/1/STATE}", "qos":0, "retain":true, "topic":"broker/gv90018g/OUTPUTS/1/STATE" }, { "payload":"OK", "qos":0, "retain":true, "topic":"broker/gv90018g/COMMAND" } ], "subscribe":[ { "action":"${payload}", "qos":0, "target":"PROTOCOLS/MQTT/EVENT", "topic":"broker/gv90018g/COMMAND" } ] }
Subscribe topic payload values specification for control of the output:
netio/<DEVICE_NAME>/output/1/action with payload for output control : (0 – off, 1 – on, 2 – short off, 3 – short on, 4 – toggle, 5 – no change)
Publish
when you need to send some data from device towards the broker, you have to specify it in the publish section - you can send measurement data as they are implemented, or you can use translation tables to send some pre-defined strings or even send JSON object. these attributes can be send periodicaly every time the timer reached specified value in seconds or based on value change (something like delta principle, but using only value differrence within defined period)
Hints to usage
When event send message with payload to topic.

Publish current on change (delta)
Publish output state
Publish to more than one topic with different events
Target / Source
In MQTT-flex we use targets and sources specify where to apply some change or get value. Practically it means addressing of INPUTS/OUTPUTS and adding command or variable.
- source - specifies from where the value will be read (specifies the source of data for payload, change detection, delta calculation)
- target - specifies where the data should be sent or command applied (e.g. specifies the target for ACTION)
INPUT / OUTPUT (Target) selection
NETIO Devices can have inputs and outputs which can be different type. When you want to work with some variable you have to specify on which I/O. For doing that in MQTT-flex is implemented structured addressing with "/" separator. See the steps below how to compose source or target.
- At first specify if requested variable is from/for INPUT or OUTPUT using keywords "OUTPUTS" or "INPUTS" .
- Add "/" separator
- Specify the number of INPUT/OUTPUT to 1(or TOTAL for summary statistics if available)
- Add "/" separator
- Specify requested variable or command
Note: Not all of OUTPUTS/INPUTS support all variables. Available variables are closely connected with the device functions and I/O features.
Note2: INPUTS available only on NETIO PowerDIN 4PZ
Examples:
adressing controll of output 3
OUTPUTS/3/ACTION
getting voltage on output 1
OUTPUTS/1/VOLTAGE
getting state of input 1
INPUTS/1/STATE
Group EventsFW 4.0.0+
Group events are smart way how to keep configuration simple. It is not replacement of publish section specification but it is extension to trigger group of different topics to be published on the same event.
See the example below. There is specific event on status change on every output and additionally the device sends periodic status every 60 seconds.

Extended MQTT flex JSON config examples
Default NETIO MQTT-flex configuration
This example demonstrates setup for connection to public broker.hivemq.com
, measurement reporting and output control.
The device cabe be controlled via netio/${DEVICE_NAME}/output/1/action topic
by sending standard NETIO action values:
- 0 - OFF
- 1 - ON
- 2 - SHORT OFF
- 3 - SHORT ON
- 4 - TOGGLE
- 5 - NO ACTION.
The device report measurements:
- Output state - every 15 minutes or by change
- Voltage [V]- every 5 minutes or by change of 1 V
- Current [mA]- every 5 minutes or by change of 50 mA
- Load(Power) [W]- every 5 minutes or by change of 10 W
- Energy(Consumption) [Wh]- every 15 minutes or by change of 1Wh
- True Power Factor (TPF) [-]- every 5 minutes or by change of 0.02
- Frequency [Hz]- every 1 hour or by change of 0.1 Hz
For register all values, you can use wildcard netio/${DEVICE_NAME}/output/1/#
