Battery level not exposed through MQTT

[fredilarsen]

I see there is a reference to the battery level in the code.
Is it easy to expose this in a "battery" MQTT topic?

It would be very advantageous to be able to include the Airthings device in battery monitoring in Home Assistant.

It is exposed

The MQTT topic is:

airthings/60:98:66:xx:xx:xx/battery
