  Version yyyymmdd  Action    Description
  --------------------------------------------------------------------------------------------

  0.9.8.0 20200705  integrate - add YEE-RC, NLIGHT and MJYD2S, add NRFUSE
  ---
  0.9.7.0 20200624  integrate - fix BEARSSL-decryption, remove MBEDTLS, prepare night light sensors
  ---
  0.9.6.1 20200622  integrate - use BEARSSL-lib for decryption as default, make decryption optional
  ---
  0.9.6.0 20200618  integrate - add decryption for LYWSD03
  ---
  0.9.5.0 20200328  integrate - add dew point, multi-page-web ui, refactoring, command interface,
                                simple beacon
  ---
  0.9.4.0 20200304  integrate - sensor types can be ignored (default for LYWSD03),
                                add CGD1 (Alarm clock), correct PDU-types for LYWSD02
  ---
  0.9.3.0 20200222  integrate - use now the correct id-word instead of MAC-OUI,
                                add CGG1
  ---
  0.9.2.0 20200212  integrate - "backports" from MI-HM10, change reading pattern,
                                add missing PDU-types, renaming driver
  ---
  0.9.1.0 20200117  integrate - Added support for the LYWSD02
  ---
  0.9.0.0 20191127  started - further development by Christian Baars
                    base    - code base from cbm80amiga, floe, Dmitry.GR
                    forked  - from arendst/tasmota            - https://github.com/arendst/Tasmota
