   39: Read data from utility meters

   Devices like smoke detectors or meters for water or heat are sending their readings via a protocol called Wireless M-Bus.

   Again, I'm surprised by how many devices seem to be around! Thanks for the tip, @envy :)

   https://wmbusmeters.org is a really nice tool for decoding the messages.
