?! — Address Query
This command queries for the WMT700 address.
When you use a question mark (?) as the address character with
the a! command, WMT700 responds as if it was being addressed
on the SDI-12 bus. Regardless of its address, WMT700 responds
to the command, which allows you to determine the address for
the wind sensor.
NOTE
If more than one WMT700 is connected to the bus, they all respond,
causing a bus contention.

where
a
= Single-digit WMT700 address that corresponds to the
first character of the address value
<CR><LF> = Terminates the response.
