Punt abbey-weather role, entirely replaced by Home Assistant.

The 1-Wire hardware was replaced with an Ecowitt IoT hub and sensors
including wind and rain.

 * The Abbey Weather Role
 
-Birchwood Abbey's weather hosts use the 1-Wire server (from the
-~owserver~ package) and a 1-Wire USB adapter.  They use an
-unprivileged account (~monkey~) to run a SystemD service named
-~weatherd~ (aka "the daemon").  The daemon is a Perl script that runs
-~owread~ and logs the new measurements once per minute.
-
-The log files are collected by Monkey on Core (via ~rsync~), then
-processed and published in campus web pages by The Weather Project's
-code (old, using ~gnuplot(1)~, and so... unpublished).
-
-** The Abbey Weather Hardware
-
-The abbey currently has one weather host, Gate, and a couple 1-Wire
-sensor modules.  The modules measure inside and outside temperature
-and humidity.  Their desired locations are 7-8m from the core servers
-so they are plugged into a custom Y cable, with the inside sensor
-cable spliced into the middle of the outside/main cable.  The proximal
-end's RJ11 plugs into a 1-Wire USB adapter (a DS9490R) plugged into
-Gate.  The outside end goes out the window with the Starlink cable.
-
-** The Abbey Weather Host Setup
-
-The Ansible code in the ~abbey-weather~ role assumes it is working
-with a cloistered host (as described in [[*Cloistering][Cloistering]]) and proceeds in
-two phases.  The first installs the ~ow-server~ package and configures
-it to use a DS9490 (USB adapter) rather than a debugging fake.  After
-the first ~./abbey config new~, the new weather host seems to need a
-reboot before the 1-Wire bus becomes visible via ~owdir~.
-
-After a reboot ~owdir~ should list one or more type 26 device IDs.
-Listing them (e.g. running ~owdir /26.nnnnnnnn~ or ~owdir
-/26.nnnnnnnn/HIH~) should reveal "files" named =temperature= and
-=HIH/humidity=.  These pseudo-file paths are used in the daemon script
-below.  A test session is shown below.
-
-#+BEGIN_EXAMPLE
-monkey@new$ owdir
-...
-    /26.2153B6000000/
-...
-monkey@new$ owdir /26.2153B6000000
-...
-    /26.2153B6000000/temperature
-...
-monkey@new$ owread /26.2153B6000000/temperature; echo
-26.125
-monkey@new$ 
-#+END_EXAMPLE
-
-The second phase of weather host configuration waits for the host-
-specific weather daemon script to appear in the role's =files/=.
-
-** The Abbey Weather Daemons
-
-Different weather hosts, with different 1-Wire devices, need different
-daemon scripts, to call ~owread~ with different paths (containing the
-IDs of each host's devices).  At the moment there is just the
-one weather host, ~anoat~.
