MQTT is implemented as M2M API protocol, where NETIO device is publisher providing output status and subscriber allowing control of NETIO power outputs (power sockets 230V or power outlets IEC-320 110/230V). With MQTT-flex the users can easily define the MQTT topics and payloads.

PowerCable firmware – 2.1.0 and later

Broker section

Parameters: Item Description Example/values url MQTT broker URL broker.hivemq.com (mqtts://broker.your-lovely-domain.com - to connect to SSL capable MQTT broker) Port MQTT broker port 1883 Ssl SSL security selector [false|true] Type Communication/setup type option [generic] (reserved for future use) username Credentials for MQTT broker - username freedom password Credentials for MQTT broker - password peace|LOVE|empathy4ALL clientid [optional] MQTT clientid. Max. 32 characters. Variables ${DEVICE_MAC} or ${DEVICE_NAME} can be used. myUniqueID1234 keepalive [optional] MQTT keep alive period in seconds 90

Subscribe topic 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 topics for monitoring of the output state and load:

• netio/<DEVICE_NAME>/output/1/state with payload providing output 1 state value - published when the output state change • netio/<DEVICE_NAME>/output/1/load with payload providing actual load of output 1 – published every 1111 seconds or when load change by 1W
