## WMBUS NODEMCU V3 + CC1101 for Diehl IZAR RC 868 I R4 PL
## HARDWARE:  NODEMCU V3 ESP8266 80MHz, 80KB RAM, 4MB Flash
##
## CC1101 TESTCASE FOR ALL WATERMETERS
##
## usage:  1. Using Homassistant API (discovery + devices)
##         2. Optional uses backup component
##         3. Optinal usese syslog component
##
## This version shows data from the all watermeters.
## Use this for frist test to find your watermeterID.
##
## DO NOT USE THIS CONFIGURATION FOR PRODUCTION
