In my firewall logs, I see that the HA server wants to connect to “https://mqtt.messagehub.de/”. The domain is shut down and is blocked by the firewall. Does anyone know which integration or APP is transmitting home?
Thanks
What integrations and addons do you have installed?
It could be any of them.
Specifically which of those not listed as local or installed from HACS(3rd party not official)
Since it’s “de” domain is there anything specifically German related.
