can you share your software (perl and/or python scripts) for mixing valves.
Then this water is mixed down to a lower
temperature for each heating circuit: a floor-heating-circuit and a
radiant-heater-circuit.

Not a complete solution by any means, but my control program 'touches' a
heatbeat file each scan (20 seconds or so) and I have a separate monitor
program that looks at the heartbeat file and if it is more than a few
minutes old it sends me an email to say that something has gone wrong.

Hi.
I use some similar relay circuits myself, mostly for controlling large
heaters on a home brewery setup. I do worry about the failure modes
that could occur during use, moreso that the startup state. In
particular, some time ago, I had trouble with my 1-wire network that
would result in owfs
Mike,
I like reliability for my house for an important reason. Whenever it
breaks, my wife points out to me that if we had bough a regular system
this wouldn't be a problem. :(
I tried X10 for some other stuff, and think is just a terrible solution
for almost anything. The X10 lighting is the thi
Hi Mick,
I'm also running a heating system with owfs and 1-wire, some perl and
python scripts and MB-Logic as HMI. I have a wood-burning oven with 18kW
heating water in a 800l buffer. Then this water is mixed down to a lower
temperature for each heating circuit: a floor-heating-circuit and a

If your embedded design uses the w1 kernel module to control the gpio pin,
owfs can use it as a generic 1-wire bus master and allow all the functions
of the DS2770 to be used.
Basically you start the program with the --w1 argument to use w1. You need
to be root to access the kernel module (and com
Hi Jerry,
Your system sounds interesting. I also have a control system based upon
1-wire and Python which controls a solar (hot water) heating system
heating the domestic hot water and a swimming pool. My plan is to
extend it to control the whole of the central heating system as well.

Hi, I'm working in an embedded project. In the project we use atmel
at91sam9g45 processor, it link to dallas 1-wire bus via GPIO to control
ds2770 chip. I don't know how to do that. I find w1 driver in the linux
kenel 3.0.7, it seems meet my need, but i didn't find ds2770 slave in the
kernel source
