OK, I'm not a big 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.

WEL Starter Kit Enc. (p/n WEL-SK-ENC) This is for someone who wants a turn-key monitoring system. This includes the latest WEL 4.5 Processor (WEL) in a transparent enclosure with a high-efficiency plug-in power supply (WEL-PWR). It also includes 10 Temperature Sensors, 40 feet of 24AWG twisted triad wire (BUS40-24AWG) suitable for the 1-Wire bus, plus 25 inline-crimps Each of these components are describe below with any associated documentation. You can also choose from 6 different combinations of Epoxy Potted (TSENSE-POT), or 1" Stainless Steel (TSENSE-SS1-1M) temperature probes. The potted sensors are great for measuring air temperatures, and the Steel ones are easy to strap to pipes for measuring water temperature.
Price: $535 each (+ tax in MD)
(Best value with a $21 saving)

The bare minimum WEL purchase is just the WEL 4.5 Processor mounted in a custom transparent enclosure (same as the one used in the starter kit). 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

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: $20 each (+ tax in MD) |

Note: The wire colors for this device are NOT-Logical. Red is Gnd, and Black is the 1-Wire Bus. Wiring Tips Price: $12 each (+ tax in MD) |

All 8 Thermostat 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 1mA 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 W1 lines of a HVAC unit's controller board to detect a Low Heat call. Installation can be tricky, so read the User Guide, for more details.
Price: $95, or $85 without the box. See pull down
list above. Make your selection before adding to cart. (+ tax in MD) |

The WEL counts pulses over each 1 minute interval, and can apply any desired scale to convert to real-world units, like GPM. It can also apply a range of "treatments" enabling it to accumulate total counts or calculate total flow or power usage on a per/day and per/month basis. There are two flavors of this device. The standard unit can read 6 pulse streams, but the minimal unit is built to just read 2 pulse streams. You can also choose to use it with, or without, a plastic enclosure. For more information, read the User Guide

One example use for this module would be to monitor a set of 8 pumps for run-times. The WELCS-8 would be mounted near the pumps, and individual Current Switches would be attached to each pump power feed. The WELCS-8 would be connected to a single 1-wire bus run, and no dedicated power would be required at that location. This unit is parasitically powered from the 1-wire bus). Note: The alternative would be to run a set of 8 Current Switch wires back to the WEL. This solution would be less expansice, but possibly also less convenient.
Price: $85 including the enclosure. (+ tax in MD) |

This small module makes it easy to create a star hub next to your WEL.
Putting lots of solid wires into a single screw terminal isn't the best wiring practice, so instead, you can use this hub to tie several wire runs together.
It has 6 terminal blocks that are all just wired together. Two 3-wire and four 2-wire terminal blocks make it easy to form a hub, or attach in a group of sensors.
Each terminal is labeled with my standard wire color code: Black (Gnd), Yellow (Bus), Red (Pwr), and there are 4 mounting holes if you want to attach it to the wall.
Using a hub like this also makes it easy to disconnect a bus run for testing, or for upgrades. (Click pic for expanded view).
Note: Since this is just a passive wiring hub, you still shouldn't use it to add a long branch to an existing bus run.
Splitting a long bus run part way down it's length can degrade the signal sufficianty to cause sensor reading problems.
Always have the center of a network star located right at the WEL, and keep any branches off a long run as short as possible.

They are Gel filled for a moisture proof connection, and they have a cool two step connection process. First you clip them on the bus with finger pressure, then you insert the sensor wire, and crimp them with pliers or crimp tool (see below). Watch my you-tube video for tips on how to install them. Price: $8 for a pack of 25 crimps (+ tax in MD) |

These are soldly built and have flat jaw design with a hard stop that prevents over-crimping. |

..... like Fire or Flood or Lightning. And then there are times when we just do something DUMB ..... like wiring power to the wrong terminals, or dropping the WEL in a bucket of water. Sometimes you just need a new WEL because ... well... don't ask! In these cases if you just send me your dead WEL with all the parts intact, I'll send you a brand new one to replace it. Since you've already paid for the software on your WEL, I'll discount the replacement unit by 50%. If you send me a Configuration Backup file (UserBlock.dat) for your old WEL I'll even load it for you.
When you purchase, add a note to tell me which WEL this is a replacement for.
I'll need to have your unit in hand before I send the replacement, so use the address below to mail/ship me your dead WEL.

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.
