Client ID

Topics
– Topics are keywords that the MQTT broker uses to filter messages for the MQTT clients. Topics are organised in a hierarchy,
akin to a folder or directory. For example, a broker may organise topics as:
– home/groundfloor/livingroom/light | home/firstfloor/kitchen/temperature
– When a publisher has a new item of data to distribute, it sends a control message with the data to the connected broker. The
broker then distributes the information to any clients that have subscribed to that topic.
Quality of Service (QoS)
– Quality of Service (QoS) in MQTT messaging is an agreement between sender and receiver on the guarantee of delivering a
message. The PWR4IEC can choose between two levels of QoS:
– QoS Level 0
– The client simply publishes the message, and there is no acknowledgement by the broker (no response is required).
– QoS Level 1
– The broker sends an acknowledgement back to the sender once the message is received; in the event that the
acknowledgement is lost, the sender will realise the message hasn’t got through and will send the message again. The
client will re-send until it gets the broker’s acknowledgement. This means that sending is guaranteed, although the
message may reach the broker more than once.
Keep -alive ping interval
– Keep Alive is a feature of the MQTT protocol that allows an MQTT client to maintain its connection with a broker by sending
regular control packets to the broker. The MQTT client is responsible for setting an appropriate keep-alive interval, for
example: basing it on it’s current signal strength, optimizing the connection for it’s specific circumstances.
– The maximum interval is 18h 12m 15s
– The minimum interval is 0s, eectively deactivating the mechanism
Publish device summary data interval
– Interval the PWR4IEC will publish it’s data
