+# SWETUP garage door opener
+# by FoxWhiskey 2023
+#
+# A four-button remote control device most likely based on EV1527 chip.
+# The device is available on AMAZON and a no-name-product branded for the german market.
+# See https://www.amazon.de/-/en/Handheld-Transmitter-Control-Universal-Wireless/dp/B09HWY1KH7
+#
+# The package includes a set of two devices. Each device, however, transmits identical signals, which suggests
+# that no ID is present and all devices are indistinguishable (if not trained to a specific code...)
+# When a button is pressed, the device transmits a 25bit code with following pattern:
+#
+# Bit 1-20  : constant
+# Bit 21-24 : BUTTON
+# Bit 25    : constant
+#
+# The pattern is being repeated as long as the button is held down. So, postprocessing is necessary if duplicates are unwanted.
+#
