Is there a little box that I could buy which would have an Ethernet port (and
IP) that I could attach to my home network and would allow me to use my computer
to monitor the status of the mains voltages circuits (of my central heating
system)?

Most of the "smart" UPSes can monitor mains voltage, and have the added
benefit of keeping your PC going even when it reaches zero volts :-)

One of the better APC SmartUPS boxes will do what you want. The cheaper
ones have USB rather than Ethernet (although many come with software to
allow the control and status information to be passed over a LAN as well).

I think that the original poster wanted something that would monitor
voltages in his heating system which a simple UPS won't do all that
well..

Have a look at

http://www.moxa.com

they do devices similar like COM port to IP converters could have sworn
that I saw something like this around a while ago also look at

http://www.barix.com

they do some sort of remote data stuff....and

http://www.s-connect.ltd.uk/

almost certain one of those has what you want but don't expect it to be
cheap tho!....

Depends how far you want to go, but you could try these guys:-

If voltage is what he is interested in, then they actually keep detailed
logs... he may also find it cheaper than dedicated lan aware A to D kit.

At that sort of level you could even go as far as embedded PC solutions
with a PCI A to D card...!

As you say, it depends on how much you want to pay.

You are sticking your toe into very deep water ... Google for "home
automation" and you'll find more "little boxes" than you could probably ever
wish for.

X10 is another relevant search term.

Cheers,

I thought X10 did controlling rather than monitoring?

It does. This is just an easy way to locate home automation
references.

Well he did say voltages within his heating system, so that implies more
than one voltage and not necessarily just the supply voltage

Thank you.

Yes those are the sort of thing that I am looking for :-)

I am planing to provide a zone valve control box for my replacement C/H boiler.
Looks like it will be worth extending my home cat 5e cabling as part of the job.

I bought a Linksys 'slug' for my Topfield PVR for £57. Amazing what you can get
for your money nowadays - Even from Cisco who have a car park full of Porches.

Their Tasman Drive office car park (San Jose) went very distinctly
empty after the dot com bust, and I've not noticed it full ever since,
although it's probably just over a year since I last went past.

Most people who had stock options in 7 and 8 figures left and/or
cashed in their chips long before the dotcom bust. Those who joined
near or at the peak have options that are underwater (i.e. option
price market trading price so no point in exercising). A few
unfortunates exercised at the peak, didn't make provision for CGT and
were unable to pay the tax when the stock fell.

You might have heard the expressions B2B (business to business) and
B2C (business to consumer). This was B2R. (back to reality).

Its much easier to just use some timer/thermostat units in the places you
want to control, end switches on the zone valves and wire OR them to boiler
on.
Use a 12v relay for boiler on if it needs mains and you can wire it all the
rest yourself, legally.

Yes, but not half as interesting.

You can wire it all legally anyway, mains or no mains.

That looks like a very useful piece of kit. Anyone ever used one and can
