# FHEM on the Fritz!Box 7390

(as of 2011-07-08)
AVM released after the CeBIT 2011 an image for the Fritz!Box7390 containing fhem, see this link. This image is to be installed in addition to the normal firmware. In order to use the image, you have to install a Lab version of the normal firmware before, because fhem needs the USB-Serial kernel modules in order to talk to the CUL, and these are not yet part of the "normal" firmware.
Version 19798 of this fhem-image (not the Lab firmware) configures 2 CUL devices, the first one talking FS20, the second preconfigured for HomeMatic. Autoconfigure is not enabled by default, so you'll either have to enable it or to enter the devices by hand.
The bad news with this fhem-image is, that it will start fhem in a chroot environment, i.e. you will not be able to trigger arbitrary FritzBox functions out of fhem, e.g. sending mail, enabling WLAN, etc.
This fhem-image contains a stripped down version of the perl package from the AVM fhem-image, a current version of fhem, and a modified installation script. The main difference is starting fhem in a normal (non-chroot) environment, and enabling autocreate.
When installing it, you have to confirm with an extra click that it does not have a valid AVM signature. It will reuse your old logfiles and configuration, unlike the "original" AVM firmware. Autocreate is on, and there are NO CUL devices defined in the initial configuration, you'll have to do this manually, e.g. by following the HOWTO or the command reference.
