Home of FHEM

FHEM (TM) is a GPL'd perl server for house automation. It is used to automate some common tasks in the household like switching lamps / shutters / heating / etc. and to log events like temperature / humidity / power consumption.

The program runs as a server, you can control it via web or smartphone frontends, telnet or TCP/IP directly.

In order to use FHEM you'll need a 24/7 server (NAS, RPi, PC, MacMini, etc) with a perl interpreter and some attached hardware like the CUL-, EnOcean-, Z-Wave-USB-Stick, etc. to access the actors and sensors.

It is pronounced without the h, like in feminine.

Installation

Debian/Ubuntu/Raspbian
• Install this package. For a better integration check out debian.fhem.de
Unix / OSX
• Make sure you have perl. Most certainly you will need the Device::SerialPort perl module, install it with "sudo cpan Device::SerialPort" or "apt-get install libdevice-serialport-perl".
• Download the .tar.gz package, unpack it, and change to the unpacked directory.
• start FHEM directly from this directory (perl fhem.pl fhem.cfg).
Windows
• See the FHEM Installation Windows for a detailed description.
• If you are using cygwin for your perl installation you can follow the guidelines for Unix.
Fritz!BOX

As of Fritz!OS 6.20 AVM decided to remove all possibilities to start "foreign" programs automatically after a reboot, that is why I advise against deploying FHEM on the Fritz!BOX, see also this discussion (in german). If you still insist:

On the FB7390 or FB7490 install this image. Note: it is needed additionally to the OS image from AVM.

On the FB7270 unpack this zip file to a USB-Disk, attach the disk to the FritzBox, log in, and start FHEM from there.

• support for a lot of protocols used in house automation, audio/video devices, weather services, online calendars and more.
  
• autocreating devices/logs when receiving data from a new device: start FHEM and watch how the plots of your sensors are appearing automatically.
• logging events to files or a database, with regexp filters
• notifying external programs or scripts when receiving certain events
• timed commands (e.g. switching a lamp on from sunset till midnight)
• lot of interfaces: simple text, JSON, XML, each of them over plain TCP/IP, SSL or HTTP.
• modular architecture with currently over 430 modules, easy to add your special device
• lot of frontends, choose your favorite
