I have to agree..
 
I would not use X10 either. Weeder Board or something similar http://www.weedtech.com/wtdio-m.html.
 
I love misterhouse, but I am planning on building a similar processing system ; )  and I am going to be doing it with an arduino. I would probably build one controller for each brewing system. You can still do lots of monitoring directly through this board to collect your stats or setup MH to do this for you. This way your brewing doesn't rely on a computer to keep running. If one arduino goes down all batches don't stop running, plus with MH pulling data you can get notification if there are any issues on any of the segments. There are temperature sensors (1-wire and other), relay boards, alcohol sensors etc for arduino....

Let me know how you make out. Sounds like a fun project

I'm going to try to save you some headache right now. Don't go with x10!
It's just way too unreliable. The last thing you want to do is put it on a mission critical system like a brewery. Spoiled batches all over the place.
Since you're building this all, I would recommend you go with your own, fully wired relays. They are easy to control with pretty much any micro controller board, such as an arduino

Also, while misterhouse is great and has lots if features, are you sure you wouldn't be open to going with a simpler, lower level system, made just for controlling and hardware and automation? I can't recommend anything specific that. Would work out of the box, but it's been done before, I know. Mister house would take some programming of your own as well.

Hello all --

I am in the process of building a small brewery, and have been looking
for ways to record and control as much as possible remotely. Add to this
that I am a FOSS advocate, and a bit technical, and it seems a natural
fit to use something like Misterhouse.

Here is some information to start with:

I would like to use a Raspberry Pi as the system controller. It will run
Debian. It needs to have web-based inspection and control, as well as be
able to run timed events, respond to measured items, and run macros.

I live in the UK, so parts have to be 240V compatible.

The brewery has three brewing vessels, and up to eight fermentation and
conditioning tanks.

Of the brewing vessels, two are fitted with two 3KW electric heaters
each. This is a total draw of 12KW during full-run, which is just under
13A draw each.

There are a number of pumps involved. They have a load of less than 1A each.

I would like to continuously monitor temperature in all brewing vessels,
as well as all the fermentation and conditioning tanks. I would like
some nice Cacti graphs of this.

I would like to have some sort of volume gauge for the brewing,
fermentations, and conditioning vessels as well.

It would be great to find a hydrometer that I could get remote output
from, but I haven't seen anything that works.

So I break the requirements down into the following:

Power control: this seems a no-brainer with X10, the CM15, AD10E (I am
doing all new wiring), and AM12E. Misterhouse seems very well prepared
for this.

Temperature monitoring: I have read some results from using USB
controlled thermometers, but if anyone has any experience, especially
with something that can take continual exposure to temperatures over
100C without damage, I am very happy to listen.

Volume monitoring and hydrometer (specific gravity) readings: I am sure
there is something out there, but I don't really have any idea where to
start.

If anyone has any ideas, suggestions, or sees any obvious pitfalls,
please let me know. I have done some web research over the last couple
weeks, and will start the power wiring next week, so I'd like to be sure
of at least the X10 part before I commit.

Kind regards,

travis
