/* change log:
 * 1.03	2021/10/02 trust/pairing, screensaver, less momory
 * 1.04 2021/11/09 no screensaver on V1 boards, auto detect 
 *                 board, logging (telnet, syslog, mqtt), falish
 *                 reporting much like the ACL nodes. Support V3
 *                 boards.
 * 1.05 2024/01/17 Remove dependency on EPS32_analogWrite polyfill - as it
 *                 is no longer compatible with HAL & a native method has
 *                 been added since.
