+  0.9.1.5 20201021  changed - HASS related ('null', hold back discovery), number of found sensors for RULES
+  -------
   0.9.1.4 20201020  changed - use BearSSL for decryption, revert to old TELEPERIOD-cycle as default
   -------
   0.9.1.3 20200926  changed - Improve HA discovery, make key+MAC case insensitive
