Hi there,
not exactly a FHZ1000 question, but still somewhat related ;)
I think about installing several HomeMatic-Funk-Stellantrieb devices
to all the radiators in my appartment.
In a perfect World I would then be able to control these devices
using some kind of Modem Device connected to one of my embedded Linux
Computers or homeserver via USB or serial Port.
Unfortunately there is no such thing as a perfect World.
Am I right in the assumption, that the so called BidCos protocol is
not only proprietary but also undocumented?
Is it further correct, that the BidCos based devices are at least
using a bidirectional protocol?

The latter one is about half the price of the first one which could
corroborate this belief.
I don't think, that I really need these strange thermostat devices.
Theses ones should be easily replaceable by an array of 1-wire temperature
sensors conencted to the already mentioned Linux based devices.
Any further hints?
Sven
P.S.: BTW, would Zigbee be a more standard aproach to do things like
this the way they should be done?

... and while you're at it, you can control the radiators with cheaper
(10€ or so) wired solutions. Controlling these with 1wire is however a
bit more tricky because they need PWM-modulated 220V power. (I'm
thinking about doing the same thing.)

Definitely.
