ioBroker v7 as MQTT Broker for your WQHD INSTAR Camera

Q: I installed my MQTT camera according to your guide in ioBroker. But now I do use the MQTT Adapter as my primary MQTT Broker - not as a MQTT Client. And I am unable to update Command Topics through the ioBroker object tree.

A: Start by installing the MQTT Server/broker Adapter:

INSTAR MQTT for ioBroker

Make sure that the prefix field is left empty, you check the option to publish topics if their value changed and set the Quality-of-Service to 1 - At least once:

You can now use a tool like the Mqtt Explorer to test the connection. The exclamation mark should disappear once a connection is established:

After saving the settings and restarting the MQTT adapter, your camera should push out all retained MQTT Status Topics and ioBroker will add them to the Object Tree:

You can now use a tool like Mqtt Explorer to update a Command Topic and see your cameras response in the Status Topic in ioBroker:

Note: In Broker mode the Status Topics will also be resolved to their RAW Value. So instead of seeing a value of {"val":"1"} you will have to work with the raw value 1.
