MAX! ist eine Heizungssteuerung, die die Raumtemperatur durch funkvernetzte Heizkörperthermostate an den Heizkörpern regelt. MAX! stellt eine Alternative zur FHT und HomeMatic Heizungsteuerung dar.

I’ve been a NetBSD developer for three years and it’s been my primary operating system for a long time too - on everything: routers, laptops, Raspberry Pis, PowerPC mac minis, Vortex86 embedded boards, and servers.

I’ve recently been using FreeBSD a lot at work. We have a lot of servers and embedded boards running it, and I was given the option of installing anything I wanted on my workstation. I chose FreeBSD to maintain a separation of BSDs between my work and home life ;)

I thought I’d write a little bit about some differences that stand out to me. Since everyone that knows me well knows that typical use cases like web hosting aren’t really my jam, and I’m more of an embedded, audio, and graphics person, maybe I can offer a more uncommon perspective.

This pages describes the steps required to migrate a house installation from MAX!Cube solution (using a Cube and MAX! Software from ELV/EQ-3) to FHEM on a Raspberry Pi combined with a CUL. The benefit of such a migration is to gain better logfiles, to get graphs (Desired vs. Actual temperature and Valve position) and more reliable software.

FHEM is a software, written in perl, which enables you to manage (eg. EVL) home automation devices over a Webinterface, with the Help of a radio transmitting USB Stick (CUL/CUN). As an alternative to USB Transmitters/Receivers LAN-devices can be used (CUNO/HM-CFG-LAN). I installed it on a Buffalo WZR-HP-AG300H, which has plenty of memory and storage. You might have to install it on an external usb storage or make a swapfile on the usb drive.
