Hi @AxelMarquez - the PubSubClient needs to re-subscribe to the 'dsc/Set' topic after publishing to another topic so it can listen for commands. If you're curious there are also some examples of this in the PubSubClient library examples. |

Good day 😊
Looking at the MQTT examples (HomeAssistant & HomeBridge), the mqtt.subscribe function is called every time dsc.StatusChanged = true in the loop(). But mqtt.subscribe is called as well when mqtt connects/re-connects.
I would assume the subscribe is only needed when connecting/re-connecting, is there a reason to have it in the loop()?
Many thanks for your support and awesome library!
