MQTT - OZW and other

Hello all,

I had a lot of issues since I use OZW, but I think it’s the MQTT Mosquitto Broker the problem, I thing the integration SEEMPortal with the MQTT crash the OZW.

Yesterday, I start a new clean installation of Hassio (On a NUC), I put the OZW and Mosquitto MQTT (without any configuration) and it’s work.

I want to add the SEEMPortal but for the SEEMPortal I need to put a Login and Password for MQTT but for OpenZwave I have any config MQTT.

It’s possible is this my problem ?
CAn I install an another MQTT ?

Thx a lot
