Hello all.

I don't think this subject has been discussed recently, and for me
it's quite an interesting one. This is my scenario:

A church building is currently heated by ancient gas boiler. 3 zones
(effectively S-plan), 3 thermostats and a 15-year old 3-zone basic
controller (not sure what make off hand). Different parts of the
building are used at different times each week, so someone needs to re-
program the controller every week. The building is not particularly
well insulated, and the timing is greatly affected by the weather (eg.
when it's cold, the heating has to go on at 3am to be warm enough for
10:30am, when the building is used!). Insulating the building better
now would be a huge expense, particularly as plans are being made for
a big extension (or possibly demolition) anyway.

What I really want is a central heating controller that is outside
temperature compensated. I would like the ability to program it from
the comfort of my own home, via the internet. We have a broadband
connection already in the building, so what I need is a heating
controller with an ethernet port.

This is what I've found so far:
Honeywell Hometronic (hugely expensive and radio-based - not sure if
it will work in a non-domestic setting)
Heatmiser.co.uk (not very helpful technical support, but product could
be OK)
Lots of ethernet IO boxes (cheap, but I would need to design hardware/
software to go with them - I am technically able, but lacking in time)

Does anyone have any experience of Hometronic or Heatmiser? Or come
across anyone else who does these things? Surely there must be a
sizeable market for this sort of stuff these days???

Thanks for any help!
Jon.

Ever looked at a Barix Barionet?. These do that sort of remote control
type thing and you can hang thermostats etc on them and remote open
close contacts over the net..

Heatmiser stuff is good. Tech people have been very helpful in person
and on the phone.

Well I don't know how technically literate you are, but I would set up a
broadband connected Linux server with a bunch of relays, and a web
interface, and do the whole controller in software!


Actually, its no bad idea for many homes..could connect up stats and
motorized valves via ethernet over mains..what is needed is a generic
I/O board for a PC..and a tad of software..

I'm in the process of doing something similar, though on a smaller scale).

My plan is to use ZoneMinder (ZM) running on Linux to be a server that I
can VPN into to control X10 connected devices. I want some CCTV in the
mix too, hence ZM is a natural choice.

The central heating part of X10 seems a path well travelled, as does ZM
access via the net.

ZoneMinder - http://www.zoneminder.com/
X10 - http://en.wikipedia.org/wiki/X10_%28...ry_standard%29

Hope that helps.

Thanks for the replies so far. I've never used Linux, but I could do
all of this using Labview, via windows.

I had a look at the Barix Barionet. It looks really good. Lots of IOs,
relay o/p, temp sensor inputs etc etc. I think it's just the job, but
only if I had the time. I have so many other jobs to do, I don't think
I can spare the time to design the software and hardware etc. OTOH, it
would be a lot of fun!

For the time being, does anyone know any alternatives to the Heatmiser
system? (I've decided the Honeywell system is too expensive!)

Cheers,
Jon.

Hello people,
I'm interested in doing similar for remote control of a heating system
via internet,
and while I like heatmiser a lot, it's an expensive approach.
From what I have read so far, only a DIY system would be "cheap", but
this system by proliphix
is cheaper than the heatmiser approach.

http://www.proliphix.com/NT-Basic.aspx

I figure it could be wirelessly hooked up to a router via an ethernet
to wi-fi bridge.

If anyone already has one of these, I'd be very interested to know how
it all works!
I havn't taken the plunge yet!
happy home automating guys (and gals)
cheers Franky

That's pretty much what I've done.
For the I/O, I use the house alarm system which has loads of input
and output ports, which can be monitored and controlled by the
computer. The computer also gets to see from the alarm system when
you're at home, in bed, away, etc, and automatically modifies the
heating behaviour accordingly (and heating of hot water). The
computer interfaces directly to the room stats via an i/o board
which drives a number of digital temperature sensors and
monitors the room thermostat set positions.
