Suggestion for IAQ re MQTT
I use the IAQ sensor through MQTT. Working fine, really.
Just one point:
Could you improve the firmware so it will mark it mqtt messages as "retain"?
When connecting to the mqtt topic the client currently does not get any information. When the retain flag is set the client will get the last information at least. Otherwise it has to wait for the next update.
With "retain" you get immediately a status.
