+### Available Characters for HOSTNAME

+  ASSUMPTIONS
+  1. A "name" (Net, Host, Gateway, or Domain name) is a text string up
+   to 24 characters drawn from the alphabet (A-Z), digits (0-9), minus
+   sign (-), and period (.).  Note that periods are only allowed when
+   they serve to delimit components of "domain style names". (See
+   RFC-921, "Domain Name System Implementation Schedule", for
+   background).  No blank or space characters are permitted as part of a
+   name. No distinction is made between upper and lower case.  The first
+   character must be an alpha character.  The last character must not be
+   a minus sign or period.  A host which serves as a GATEWAY should have
+   "-GATEWAY" or "-GW" as part of its name.  Hosts which do not serve as
+   Internet gateways should not use "-GATEWAY" and "-GW" as part of
+   their names. A host which is a TAC should have "-TAC" as the last
+   part of its host name, if it is a DoD host.  Single character names
+   or nicknames are not allowed.

 Initially I had one MQTT configurable topic planned called TOPIC but soon found out that when two sonoffs come online with the same topic this would be a challenge at least...
