Take a look at the homie convention:

3.3 QoS and retained messages

The nature of the Homie convention makes it safe about duplicate messages, so the recommended QoS for reliability is QoS 1 . All messages MUST be sent as retained , UNLESS stated otherwise.

So if your device can’t do it you have to configure your broker to do it. Storing and saving QoS=0 Messages with retained flag is within the MQTT spec 3.3(?). The broker even „should“ keep those messages.
