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
+HM-CFG-USB in [Fhem][] or as a lan configuration tool for the [CCU][] or the
HomeMatic windows configuration software, also supporting devices using
AES-signing like [KeyMatic][].

### Short hmland HowTo: ###
1. Install prerequisites:
`apt-get install libusb-1.0-0-dev build-essential git`
2. Get the current version of this software (choose **one** option):
- * Get the current version via git (can be easily updated with `git pull`):
+ * Get the current *release*-version as a .tar.gz:
+ 1. Download the latest version from the [releases-directory][].
+ Version 0.100 is used as an example for the following commands.
+ 2. Extract the archive: `tar xzf hmcfgusb-0.100.tar.gz`
+ 3. Change into the new directory: `cd hmcfgusb-0.100`
+ * Get the current *development*-version via git (can be easily updated with `git pull`):
1. `git clone git://git.zerfleddert.de/hmcfgusb`
2. Change into the new directory: `cd hmcfgusb`
- * Get the current version as an archive:
+ * Get the current *development*-version as an archive:
1. [hmcfgusb-HEAD-xxxxxxx.tar.gz][] (xxxxxxx is part of the commit-id.
xxxxxxx is just a placeholder for this HowTo, use your value)
2. Extract the archive: `tar xzf hmcfgusb-HEAD-xxxxxxx.tar.gz`
``define hmusb HMLAN 127.0.0.1:1234``
``attr hmusb hmId <hmId>``
+**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)
