+# Friedland EVO door bell
+#
+# This decodes the transmissions from the Friedland EVO wireless door bell buttons. The
+# Friedland doorbell system allows multiple buttons and multiple bells and will make a
+# different sound depending on which door button was pressed. This has only been tested with
+# 2 different buttons.
+#
+# In order to eliminate other transmissions the match function has been used with part of
+# the data that was the same between the two tested variants. This may not hold true for
+# different devices so be prepared to remove/adjust as needed.
+#
+# The frequency is around 433.8Mhz
+#
+# Note: The buttons send out the same data 12 times so you may need to write a filter
+# to pipe the output through to remove them
