The HM-CFG-USB can be used to send and receive [BidCoS-Packets][] to control
[HomeMatic][] home automation devices (like remote controllable sockets,
This repository contains, amongst others, an application, which emulates the
HomeMatic LAN configuration adapter-protocol to make it possible to use the
-HM-CFG-USB in [Fhem][] or as a lan configuration tool for the CCU or the

AES-signing like [KeyMatic][].

### Short hmland HowTo: ###
``define hmusb HMLAN 127.0.0.1:1234``
``attr hmusb hmId <hmId>``
-**Important compatibility information:**
-If older Fhem-versions (before 2015-06-19) or other software ([Homegear][],
-[LXCCU][], a real [CCU][], Windows configuration software, ...) is used
-to connect to hmland, the `-I` switch might be needed to impersonate a
-LAN-interface (this replaces the identity string HM-USB-IF with HM-LAN-IF).
+**Important compatibility information:**
+If older Fhem-versions (before 2015-06-19) or [Homegear][] before 2015-07-01
+is used to connect to hmland, the `-I` switch might be needed to
+impersonate a LAN-interface (this replaces the identity string HM-USB-IF with
+HM-LAN-IF). eQ-3 rfd (CCU and configuration software) works without this switch.
Software which needs this will not keep a stable connection open to
hmland without this switch. It was the hardcoded default in versions
< 0.100.
This incompatibility is needed so connecting software is able to
differentiate between HM-CFG-LAN and HM-CFG-USB.
+**Important security information:**
+Versions before 0.101 do not correctly transmit the AES channel-mask
+to the HM-CFG-USB, which results in signature-requests not being generated
+by the device in most cases. This can lead to processing of unsigned messages
+by the host-software. If you are relying on authenticated messages
+(with e.g. aesCommReq in Fhem) from devices like door-sensors and remotes,
+you should upgrade to at least version 0.101.

### Updating the HM-CFG-USB firmware to version 0.967: ###
1. Compile the hmcfgusb utilities like in the hmland HowTo above
(steps 1 to 5) and stay in the directory
-2. Download the new firmware: [hmusbif.03c7.enc][]:
+2. Download the new firmware: [hmusbif.03c7.enc][] (extracted from the
+ [Firmware update tool][]):
`wget https://git.zerfleddert.de/hmcfgusb/firmware/hmusbif.03c7.enc`
3. Make sure that hmland is not running
4. Flash the update to the USB-stick:
`./flash-hmcfgusb hmusbif.03c7.enc` (You might need to use `sudo` for this)

### Updating HomemMatic devices over the air (OTA) (also for CUL devices): ###
the new firmware to the device with serial *KEQ0123456*:
`./flash-ota -f hm_cc_rt_dn_update_V1_4_001_141020.eq3 -s KEQ0123456 -c /dev/ttyACM0`
+**Automatic firmware-updates:**
+The options `-C` (HMID of central), `-D` (HMID of device) and `-K` (AES key w/
+index) can be used to send a device to the bootloader automatically without
+manually rebooting the device while pressing buttons:
+
+`./flash-ota -f hm_cc_rt_dn_update_V1_4_001_141020.eq3 -C ABCDEF -D 012345 -K 01:00112233445566778899AABBCCDDEEFF`
+
+`-K` is only needed, when AES signing is active on the device.

+signing-requests with culfw-devices.
