Hi,

Once again thank you for your great work. I upgraded my EVO from EVO48 to new EVOHD and upgraded IP150 to version 4.42. I can now log in just fine on my panel via IP and panel serial number. I have got the mosquitto broker set up and using MQTT Explorer i can see the paradox topics being publish and refreshed just fine. However, i just dont seem to be able to get this working on homeassistant (it is running via docker-compose on the same raspberry pi as the mosquitto broker and the pai script). I followed the wiki instructions, but i always get the "Intergration has no devices" message under the MQTT integration. I have set up MQTT_HOMEASSISTANT_AUTODISCOVERY_ENABLE = True in pai.conf and added the instructed lines (i.e.under mqtt: the broker IP, username, pass and discovery true) in configuration.yaml. As mentioned via MQTT Explorer i can see that both "paradox" (with correct states/zones events etc) and "homeassistant" (with binary sensors etc) topics are being published and are correctly refreshing. I also did a test via homeassistant->developer tools->mqtt to publish something and i can successfully see it in MQTT Explorer. I can also publish something via MQTT Explorer and see it in homeassistant if i listen for the topic in developer tools (so homeassistant seems to successfully connect to mosquitto MQTT broker). Yet i keep getting the intergration has not devices message in homeassistant. I have restarted the server several times but no luck. Any idea why i cant see my paradox mqtt topic in homeassistant? 
Thank you again for all the excellent work!!
