+# Hörmann (Hoermann/Hormann) remote for 868 MHz (Blue Button).
+#
+# This remote control is used for garage doors and gates.
+# Decodes all 868 MHz senders (blue button):
+# - HSM2 868
+# - HSM4 868
+# - HS1 868
+# - HS3 868
+# - HS4 868
+# - HSZ1 868
+# - HSZ2 868
+# - HSP4 868
+# - HSP4-C 868
+# - HSD2-A 868
+# - HSD2-C 868
+#
+# It transmits on 868.3 MHz and uses OOK PWM encoding,
+# Usually 10 repeats of 32 bits with
+# - 5328 us warmup pulse (16 clocks), 333 us gap
+# - 0 is encoded as 667 us pulse and 333 us gap.
+# - 1 is encoded as 333 us pulse and 667 us gap,
+#
+# -X 'n=Hormann,m=OOK_PWM,s=333,l=667,y=5328,r=900'
