I would suggest that we are using a secured channel for the communication by default, if possible.

[ludeeus]

It is possible, but I think that would confuse the potential enduser?
Home Assistant itself and most of the components/platforms do have this as false by defaul?

I do not disagree with the suggestion, but to my knowledge, there is not a standard that a component or a platform should have that enabled by default, it may be something to discuss in https://github.com/home-assistant/architecture?

[amelchio]

I think it makes a difference where the target is located. Devices on the LAN usually do not have valid certificates anyway.

Connections to servers on the internet should default to SSL with verification.

[ludeeus]

I'm not sure if their paid service is running SSL, but the demo versions are not.
For the local version they do not have built-in support for SSL, you would have to run it behind a proxy to get that for a local instance.
I have used a local instance (hassio add-on) while building and testing this.

This looks good to me but I am no device_tracker wizard.

[deanrparry]

very nice indeed :) was using a custom component before which i tweaked with battery etc... any chances that monitored conditions could be added to this to allow additional fields? factoring in if two devices have different fields available etc... then sir you will be a god lol
