| | 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][]. |

| | 23 | ### Short hmland HowTo: ### |
| | 24 | |
| | 25 | 1. Install prerequisites: |
| | 26 | `apt-get install libusb-1.0-0-dev build-essential git` |
| | 27 | 2. Get the current version of this software (choose **one** option): |
| | 28 | * Get the current *release*-version as a .tar.gz: |
| | 29 | 1. Download the latest version from the [releases-directory][]. |
| | 30 | Version 0.100 is used as an example for the following commands. |
| | 31 | 2. Extract the archive: `tar xzf hmcfgusb-0.100.tar.gz` |
| | 32 | 3. Change into the new directory: `cd hmcfgusb-0.100` |
| | 33 | * Get the current *development*-version via git (can be easily updated with `git pull`): |
| | 34 | 1. `git clone git://git.zerfleddert.de/hmcfgusb` |
| | 35 | 2. Change into the new directory: `cd hmcfgusb` |
| | 36 | * Get the current *development*-version as an archive: |
| | 37 | 1. [hmcfgusb-HEAD-xxxxxxx.tar.gz][] (xxxxxxx is part of the commit-id. |
| | 38 | xxxxxxx is just a placeholder for this HowTo, use your value) |
| | 39 | 2. Extract the archive: `tar xzf hmcfgusb-HEAD-xxxxxxx.tar.gz` |
| | 40 | 3. Change into the new directory: `cd hmcfgusb-HEAD-xxxxxxx` |
| | 41 | 3. Build the code: `make` |
| | 42 | 4. Optional: Install udev-rules so normal users can access the device: |
| | 43 | `sudo cp hmcfgusb.rules /etc/udev/rules.d/` |
| | 44 | 5. Plug in the HM-CFG-USB |
| | 45 | 6. Run hmland (with debugging the first time, see `-h` switch): |
| | 46 | `./hmland -p 1234 -D` |
| | 47 | 7. Configure Fhem to use your new HMLAN device: |
| | 48 | ``define hmusb HMLAN 127.0.0.1:1234`` |
| | 49 | ``attr hmusb hmId <hmId>`` |
| | 50 | |
| | 51 | **Important compatibility information:** |
| | 52 | If older Fhem-versions (before 2015-06-19) or [Homegear][] before 2015-07-01 |
| | 53 | is used to connect to hmland, the `-I` switch might be needed to |
| | 54 | impersonate a LAN-interface (this replaces the identity string HM-USB-IF with |
| | 55 | HM-LAN-IF). eQ-3 rfd (CCU and configuration software) works without this switch. |
| | 56 | Software which needs this will not keep a stable connection open to |
| | 57 | hmland without this switch. It was the hardcoded default in versions |
| | 58 | < 0.100. |
| | 59 | |
| | 60 | This incompatibility is needed so connecting software is able to |
| | 61 | differentiate between HM-CFG-LAN and HM-CFG-USB. |
| | 62 | |
| | 63 | **Important security information:** |
| | 64 | Versions before 0.101 do not correctly transmit the AES channel-mask |
| | 65 | to the HM-CFG-USB, which results in signature-requests not being generated |
| | 66 | by the device in most cases. This can lead to processing of unsigned messages |
| | 67 | by the host-software. If you are relying on authenticated messages |
| | 68 | (with e.g. aesCommReq in Fhem) from devices like door-sensors and remotes, |
| | 69 | you should upgrade to at least version 0.101. |

| | 75 | ### Updating the HM-CFG-USB firmware to version 0.967: ### |
| | 76 | |
| | 77 | 1. Compile the hmcfgusb utilities like in the hmland HowTo above |
| | 78 | (steps 1 to 5) and stay in the directory |
| | 79 | 2. Download the new firmware: [hmusbif.03c7.enc][] (extracted from the |
| | 80 | [Firmware update tool][]): |
| | 81 | `wget https://git.zerfleddert.de/hmcfgusb/firmware/hmusbif.03c7.enc` |
| | 82 | 3. Make sure that hmland is not running |
| | 83 | 4. Flash the update to the USB-stick: |
| | 84 | `./flash-hmcfgusb hmusbif.03c7.enc` (You might need to use `sudo` for this) |
| | 85 | |
| | 86 | [hmusbif.03c7.enc]: https://git.zerfleddert.de/hmcfgusb/firmware/hmusbif.03c7.enc |
| | 87 | [Firmware update tool]: http://www.eq-3.de/Downloads/Software/Firmware%20Update%20Tool/HM-CFG-USB-2_FW-UpdateTool-Usersoftware_V1_1_eQ-3_140619.zip |
| | 88 | |
| | 89 | ### Updating HomemMatic devices over the air (OTA) (also for CUL devices): ### |
| | 90 | |
| | 91 | 1. Compile the hmcfgusb utilities like in the hmland HowTo above |
| | 92 | (steps 1 to 5) and stay in the directory |
| | 93 | 2. Download the new firmware from [eQ-3][], in this example the HM-CC-RT-DN |
| | 94 | firmware version 1.4 |
| | 95 | 3. Extract the tgz-file: `tar xvzf hm_cc_rt_dn_update_V1_4_001_141020.tgz` |
| | 96 | 4. Make sure that hmland is not running |
| | 97 | * When using the **[HM-CFG-USB(2)][]**, flash the new firmware to the device |
| | 98 | with serial *KEQ0123456*: |
| | 99 | `./flash-ota -f hm_cc_rt_dn_update_V1_4_001_141020.eq3 -s KEQ0123456` |
| | 100 | * When using a **[culfw][]**-based device (**[CUL][]/[COC][]/...**), flash |
| | 101 | the new firmware to the device with serial *KEQ0123456*: |
| | 102 | `./flash-ota -f hm_cc_rt_dn_update_V1_4_001_141020.eq3 -s KEQ0123456 -c /dev/ttyACM0` |
| | 103 | |
| | 104 | **Automatic firmware-updates:** |
| | 105 | The options `-C` (HMID of central), `-D` (HMID of device) and `-K` (AES key w/ |
| | 106 | index) can be used to send a device to the bootloader automatically without |
| | 107 | manually rebooting the device while pressing buttons: |
| | 108 | |
| | 109 | `./flash-ota -f hm_cc_rt_dn_update_V1_4_001_141020.eq3 -C ABCDEF -D 012345 -K 01:00112233445566778899AABBCCDDEEFF` |
| | 110 | |
| | 111 | `-K` is only needed, when AES signing is active on the device. |
