I wanted to use the mqtt binding of openhab to connect to a cloud mqtt broker.
I know that tcp connection works but for such external connections I very much prefer to use encryption. I am not sure if the mqtt binding supports secure connections.
I have some other topics where we are instructed to create a java keystore, create a pair of certs etc etc but it is not needed in my case. As I am using the client to connect to a server in the cloud I only need to trust the server’s certificate so basically I need to have their root cert in openhab’s trustore.
Is this possible ? What’s the cert truststore of openhab ? I do not want to create a certificate myself because the cloud server does not need it
