MQTT sensor auto publish ?
### Describe the feature request

Would it be possible to add a setting for sensors to auto publish sensor metrics?, I currently have to run mac/attrib/get requests for each sensor x each attribute.

`unifi/protect/9C05D63EF008/ambientlight/get` polling


### Describe the proposed solution

Add a mqtt autopublish period in settings, or detect updates from protect and trigger.


### Describe alternatives you have considered to the enhancement

or easier perhaps, Add a local mqtt loopback timer with a user input for all the topics, and call that internally.

```
-- topics to publish 1 per line
unifi/protect/9C05D63EF008/ambientlight/get
unifi/protect/9C05D63EF008/temperature/get
...
```

```
-- interval(s)
600
```

If I missing something obvious to do this, right now using nodered timers
