README: add links for culfw and devices

[hmcfgusb] / README.md

This repository contains utilities to use the [HM-CFG-USB(2)][] (HomeMatic USB
Konfigurations-Adapter) from [ELV][] on Linux/Unix by using [libusb 1.0][].

The HM-CFG-USB can be used to send and receive [BidCoS-Packets][] to control
[HomeMatic][] home automation devices (like remote controllable sockets,
switches, sensors, ...).

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
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`):
        1.  `git clone git://git.zerfleddert.de/hmcfgusb`
        2.  Change into the new directory: `cd hmcfgusb`
    *   Get the current 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`
        3.  Change into the new directory: `cd hmcfgusb-HEAD-xxxxxxx`
3.  Build the code: `make`
4.  Optional: Install udev-rules so normal users can access the device:
    `sudo cp hmcfgusb.rules /etc/udev/rules.d/`
5.  Plug in the HM-CFG-USB
6.  Run hmland (with debugging the first time, see `-h` switch):
    `./hmland -p 1234 -D`
7.  Configure Fhem to use your new HMLAN device:  
    ``define hmusb HMLAN 127.0.0.1:1234``  
    ``attr hmusb hmId <hmId>``

### 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][]:
    `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)

[hmusbif.03c7.enc]: https://git.zerfleddert.de/hmcfgusb/firmware/hmusbif.03c7.enc

### Updating HomemMatic devices over the air (OTA): ###

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 from [eQ-3][], in this example the HM-CC-RT-DN
    firmware version 1.4
3.  Extract the tgz-file: `tar xvzf hm_cc_rt_dn_update_V1_4_001_141020.tgz`
4.  Make sure that hmland is not running
*   When using the **HM-CFG-USB**, flash the new firmware to the device with
    serial *KEQ0123456*:  
     `./flash-ota -f hm_cc_rt_dn_update_V1_4_001_141020.eq3 -s KEQ0123456`
*   When using a **[culfw][]**-based device (**[CUL][]/[COC][]/...**), flash
    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`
