Problems with popp hub

[arksantos]

I downloaded the Base module App and the MQTT App on my Popp hub but it seems that something is working wrong. Can I know if the App or the Popp Hub is correctly connected to my MQTT broker in some way? I can see the App active but not if the app or the Pop hub is correctly connected to the mosquitto broker that is running on my computer..

I also installed the mqttspy to send and see which commands are running through the mqtt server. I know that my mqtt server is correctly running because the mqttspy is connected to it and I tried it with other devices with node-red.

I saw a message before downloading the MQTT App telling that this does not work with the Popp hub. Is this message right?

When configuring the MQTT App I can´t leave in blackor in "none" mode the Topic prefix. Can I only send Tag_20B? instead of /zway/Tag_20B?

Thanks
