Store! You call this a store?
OK, I'm not a big-time manufacture with a giant distribution system. But I
do believe in providing a quality product that performs as expected. If
you're not sure what you need, you should call or email me (see my info at the
bottom of the page).
I've tried to provide a wide range of options below, and if I don't have what
you need, I can probably tell you where to get it. If you are a DIY Dude,
just get the bare minimum WEL and build your network from scratch, otherwise the
WEL Starter Kit may be the best for you. One
great thing about the Web Energy Logger (WEL) is that you can be as self sufficient as
you want when it comes to doing it yourself.
All the software you need comes included with every WEL. This includes the
monitoring software on the WEL, and an account on the WELServer.com website for
display and logging purposes.
Here are the options and
prices. Click any image for an enlargement.

This is for someone who wants a turn-key monitoring system.
This includes the WEL 3.3 board (WEL) in a transparent enclosure with a plug-in power
supply (WEL-PWR). It also includes 10 Encapsulated Temperature Sensors
(TSENSE-ENC) and 40 feet of 24AWG twisted
triad wire (BUS40-24AWG) suitable for the
1-Wire bus. Each of these components are describe below with any
associated documentation.
All you need is a CAT5 cable to
plug the WEL into your Local Area Network.
Price: $525 each (+ tax in MD)
(Best value with a $25 saving) |
 |
The bare minimum WEL purchase is just the WEL 3.3 board
mounted in a custom transparent enclosure. You
don't need to purchase anything else from me. I'll show you exactly what
else you need to build your system, from wiring, to temperature sensors and
Watt meters. The WEL will come fully programmed and ready to post
data. Download the
User Manual, or view
the schematic P1,

Price: $375 each (+ tax in MD) |

This is just a simple "Wall Wart" that has the correct voltage (9V) and
current (600mA) for the WEL. The plug has been trimmed off
and the wires are exposed for immediate attachment to the WEL.
Price: $10 each (+ tax in MD) |
 |
Three solid-copper 24AWG wires have been twisted together to make a 1-Wire
bus that's well suited to the harsh conditions in a utility room.
This thinner bus is suited to the smaller telecomm T-Splices supplied with the
Encapsulated Temperature Sensors (below).
In addition to the standard black and yellow bus wires, a red wire is
also included for future expansion, to provide the power that some
sensors require.
Price: $15 each (+ tax in MD) |
 |
This NEW factory-Encapsulated temperature sensor is much more compact than my
previous home-made one.
The face of the sensor itself is exposed through an opening at the front of the housing so it's also
great for sensing air temperatures.
The sensor has 24" flexible 24 AWG leads attached which enable it to be located in small places (like inside an existing thermostat housing).
Small telecomm Tap-Splices are supplied with the sensor to easily add it to an existing 1-wire bus without stripping or soldering.
Anyone using these sensors should order the thinner 24 AWG bus wire (above).
NOTE: See
my
instructions for installing these new
sensors.

This item is an isolated current sense device, which can be used with
the WEL Run Monitor inputs to sense when an HVAC device has been
activated. It's ideal for circulator pumps, GSHP's, heater
elements and any device that draws more than 300 mA. You just slip
the Current Switch over one of the device's power conductors and connect
the red and black wires up to the WEL. The WEL can display if the
device is on or off, and it can record the number of hours that the
device is active each day and month. Price: $22 each (+ tax in MD) |
 |
This board can be used to monitor up to eight 24 vac
thermostat signals. All 8 inputs are optically isolated from the
1-wire bus, and each other. The WEL will register a '1' state when
12-24 vac is
present across a pair of input screw terminals. Each input draws
only 10mA from the 24 vac signal line it is monitoring. This board
does NOT generate the 24 vac, it simply monitors an existing control
signal. An input might be connected across the C and Y1 lines of a
HVAC unit's controller board to detect a Low Cool call.
The board provides a pass-through for the 1-wire bus, and it's
parasitically powered from the bus, so no external supply is
required. (schematic)

This item combines a CR Magnetics' current switch with
one of my 1-wire
Remote Run Monitor module. This enables you to monitor the operation of
devices via the 1-Wire bus, without having to run
lots of individual wire pairs. Just string one long 1-wire bus,
and attach these current switches where you need them. The picture
shown here is before the final heat shrink is added to the 1-Wire Remote
Monitor module. Price: $40 each (+ tax in MD) |
 |
This tiny module can be used to read any contact closure (or
optical switch) and feed the open/closed status onto the WEL's 1-wire
bus. This means you are not limited by the WEL's 8 on-board run
monitor inputs. You can add as many inputs as you like, wherever
you like. The
Ready To Install (RTI) version of this board comes with two pairs of
wires attached. One black/yellow pair is used to connect to the
1-wire bus, and the other black/red pair is used to connect to the
switch to be monitored. The module is sealed using Heat-Shrink.

These are raw un-mounted DS18B20-PAR or DS18S20-PAR temperature Sensors ICs. If you have
plenty of time and a steady hand, you can wire and mount these sensors yourself.
Build you own custom temperature probe. Note: these
are the Parasite-Power version of the chips that only require two
terminals to be connected. (Call if you need to know which sensor I'm
currently shipping: 301-387-2331)
Price: $20 for a pack of 5 sensors (+ tax in MD)

Do It Yourself (DIY) version of this board has no wires attached, so
soldering skills are required. The photo shows a strip of 10
boards. (schematic) Price: $14

Note: I'm trying to make it possible for people to build their own monitoring
systems without requiring a lot of nitty-gritty technical knowledge, but I am
expecting the average user to be somewhat technical, with an eagerness to learn
more about their particular system. This is consistent with what I've
discovered when dealing with people on my site. The ones considering
energy efficiency, or alternative technologies are often willing to get a bit
more "involved" with the process. And it pays off in the end.
So, if you're considering installing a Web Energy Logger in your new home or
business, feel free to call or email me to discuss your thoughts. It's
easy enough for me to ask you a few questions on the phone and help you assess
your need, rather than you having to figure it all out for yourself. It
also helps me to be able to predict likely orders, and make sure I have stock on
hand.
Phil.
The Web Energy Logger is an Internet Appliance that monitors a 1-wire sensor network, and posts live data to a web site for display and analysis.
The WEL was designed for people interested in monitoring the energy distribution of their own homes or businesses.
