   1 This repository contains utilities to use the [HM-CFG-USB(2)][] (HomeMatic USB
   2 Konfigurations-Adapter) from [ELV][] on Linux/Unix by using [libusb 1.0][].
   3
   4 The HM-CFG-USB can be used to send and receive [BidCoS-Packets][] to control
   5 [HomeMatic][] home automation devices (like remote controllable sockets,
   6 switches, sensors, ...).
   7
   8 This repository contains, amongst others, an application, which emulates the
   9 HomeMatic LAN configuration adapter-protocol to make it possible to use the
  10 HM-CFG-USB in [Fhem][] or as a lan configuration tool for the CCU or the
  11 HomeMatic windows configuration software, also supporting devices using
  12 AES-signing like [KeyMatic][].

  22 ### Short hmland HowTo: ###
  23
  24 1.  Install prerequisites:
  25     `apt-get install libusb-1.0-0-dev build-essential git`
  26 2.  Get the current version of this software (choose **one** option):
  27     *   Get the current *release*-version as a .tar.gz:
  28         1.  Download the latest version from the [releases-directory][].
  29             Version 0.100 is used as an example for the following commands.
  30         2.  Extract the archive: `tar xzf hmcfgusb-0.100.tar.gz`
  31         3.  Change into the new directory: `cd hmcfgusb-0.100`
  32     *   Get the current *development*-version via git (can be easily updated with `git pull`):
  33         1.  `git clone git://git.zerfleddert.de/hmcfgusb`
  34         2.  Change into the new directory: `cd hmcfgusb`
  35     *   Get the current *development*-version as an archive:
  36         1.  [hmcfgusb-HEAD-xxxxxxx.tar.gz][] (xxxxxxx is part of the commit-id.
  37             xxxxxxx is just a placeholder for this HowTo, use your value)
  38         2.  Extract the archive: `tar xzf hmcfgusb-HEAD-xxxxxxx.tar.gz`
  39         3.  Change into the new directory: `cd hmcfgusb-HEAD-xxxxxxx`
  40 3.  Build the code: `make`
  41 4.  Optional: Install udev-rules so normal users can access the device:
  42     `sudo cp hmcfgusb.rules /etc/udev/rules.d/`
  43 5.  Plug in the HM-CFG-USB
  44 6.  Run hmland (with debugging the first time, see `-h` switch):
  45     `./hmland -p 1234 -D`
  46 7.  Configure Fhem to use your new HMLAN device:
  47     ``define hmusb HMLAN 127.0.0.1:1234``
  48     ``attr hmusb hmId <hmId>``
  49
  50 **Important compatibility information:**
  51 If older Fhem-versions (before 2015-06-19) or other software ([Homegear][],
  52 [LXCCU][], a real [CCU][], Windows configuration software, ...) is used
  53 to connect to hmland, the `-I` switch might be needed to impersonate a
  54 LAN-interface (this replaces the identity string HM-USB-IF with HM-LAN-IF).
  55 Software which needs this will not keep a stable connection open to
  56 hmland without this switch. It was the hardcoded default in versions
  57 < 0.100.
  58
  59 This incompatibility is needed so connecting software is able to
  60 differentiate between HM-CFG-LAN and HM-CFG-USB.

  68 ### Updating the HM-CFG-USB firmware to version 0.967: ###
  69
  70 1.  Compile the hmcfgusb utilities like in the hmland HowTo above
  71     (steps 1 to 5) and stay in the directory
  72 2.  Download the new firmware: [hmusbif.03c7.enc][]:
  73     `wget https://git.zerfleddert.de/hmcfgusb/firmware/hmusbif.03c7.enc`
  74 3.  Make sure that hmland is not running
  75 4.  Flash the update to the USB-stick:
  76     `./flash-hmcfgusb hmusbif.03c7.enc` (You might need to use `sudo` for this)

  80 ### Updating HomemMatic devices over the air (OTA) (also for CUL devices): ###
  81
  82 1.  Compile the hmcfgusb utilities like in the hmland HowTo above
  83     (steps 1 to 5) and stay in the directory
  84 2.  Download the new firmware from [eQ-3][], in this example the HM-CC-RT-DN
  85     firmware version 1.4
  86 3.  Extract the tgz-file: `tar xvzf hm_cc_rt_dn_update_V1_4_001_141020.tgz`
  87 4.  Make sure that hmland is not running
  88 *   When using the **[HM-CFG-USB(2)][]**, flash the new firmware to the device
  89     with serial *KEQ0123456*:
  90      `./flash-ota -f hm_cc_rt_dn_update_V1_4_001_141020.eq3 -s KEQ0123456`
  91 *   When using a **[culfw][]**-based device (**[CUL][]/[COC][]/...**), flash
  92     the new firmware to the device with serial *KEQ0123456*:
  93      `./flash-ota -f hm_cc_rt_dn_update_V1_4_001_141020.eq3 -s KEQ0123456 -c /dev/ttyACM0`
