Support Request: Need help/examples for the mqtt part
### Describe Your Problem

I don't know what i can put in the two option fields, and how

@banboobee as far as I understand, you wrote the mqtt part. Please could you provide a little guide or help page in the wiki?

### MQTT Url
 The field hint just shows an IP but you need to give a full URL with `mqtt://192.168.x.x`. Does it work when using tls by `mqtts:` instead?

### MQTT Options
What are the possible options and how to place more than one? I think one can put username, password, psk and other mqtt-stuff, or?

### MQTT Pub Options
Are there any other options other than retain?
