Add SSID information as a device sensor to help monitoring #813
Description
Is your feature request related to a problem? Please describe.
To help in the task to monitoring devices and entities, it would be great to know which SSID the device is connected.
Describe the solution you'd like
I have only LG's HVAC appliances, so my experience is limited only to this device class.
It would be nice to have a sensor with SSID information. In a installation with many different SSIDs (like mine), knowing which HVAC is connect to which SSID (without entering LG Thinq App) one can monitor and take actions based on this information.
If possible or provided by Thinq a great sensor is "BSSID" mac address information too.
Describe alternatives you've considered
If a sensor is not possible / planned an alternative is to add an attribute to the entity.
Additional context
Many integrations have this kind of functionality. I can list some - OpenBEKEN devices (switches, bulbs, power plugs etc) with MQTT integration and Tasmota integration. I guess that ESPHome provides these data too.
