I confirmed with the software author that's the case. Anything stronger than -40dbm is not metered, and instead just gives the "Bat signal" lol.
However, this does present a good point. In my bedroom, where I spend 8+ hours a day, I'm getting bombarded by the site. Starting to wonder if there are any health risks. This level is much stronger than even my WiFi router, which is about -60dbm in my bedroom.
