Regarding the pulse output. I copied this excerpt from page 25/26 of the manual from wattnode. The pulse output are typical open collectors. There is some knowledge required to hook these up. The total kWh is a simple function of counting the pulses. The instantaneous kW is a calculation...

Apologies not necessary. This doesn't look any different from the wattnode. I only saw pulse output meters on the website at similar prices as wattnode. Please note I don't endorse either...I just endorse the facts.

It is easy to connect the pulse output version to a meter, but you sacrifice information that the network version has -that's why it's more money. I know what you're getting at, but just because the information is there doesn't mean it is exposed without paying for the software. If you want...

For the LonWorks version: The electrical standard (rs-485) doesn't have much relavance to ease of integration, having the correct drivers available to poll the device does. What do you plan on integrating it with? The device is packed with useful information, but the software is more than the...

I'm not sure I understand the question, but I monitor my power so I can see power demand from various appliances and see where my biggest users are and try to reduce my consumption some. I can also trigger various events if specific condtions exist. I can set up my own automatic cash totalizer...

I did this with UPB and my PLC. You can do this with a UPB controller and the UPB i/o module..caution though; this requires some modifications of the OEM fan controller circuitry and isn't too difficult. Essentially, I replaced the manually operated swithces/pull chains with relays and used my...

"... Measures real power usage (voltage*ampere) in steps of 1 Watt/Hr. ..." These are lame, especially for the cost, and don't measure real power. They measure apparent power (S or VA). You get billed for real power (P measured in kW for instantaneous or kWh for total usage) so comparing this...

Hi, thanks. It is my home security/automation system. I used a D4-450 CPU from Automation Direct for centralized control. It's on the top backplane. The three below it are local expansion units. The is a variety of I/O; DC inputs and outputs, AC inputs and outputs, relay outputs, analog...

I have the unit between my floor joists in the basement near the front of the house. I can reliably transmit from anywhere inside (raised ranch ~1800ft^2+bsmt) and about a 50' radius outside +/- a few feet. I think it's one of the best components of my system for its simplicity and...

http://www.hobbyengineering.com/H1744.html I use one of these for remote control commands. Just wire the dry contacts into your controllers inputs and write your code. They work great. So good, I pulled my garage door motor control board out and made my own so I can control it from my system...

Not and ELK, but I couldn't resist any longer. The close up is the DVR pc.

********* Sure but it needs to be a constructive comment that he can use to improve things. What kind of graphics were you thinking of? He has the fancy overlay examples for the garage door. Are you looking for a more decorative font for the event log or what exactly? Also what would be an...

Better graphics of course. ODBC connectivity. and more. I don't care about media control. I have no interest in it, just like this this software. The guy wanted an honest comment. I gave it.

Recirculation pumps?? I circulate my hot water through a loop without a pump. Do you know if your water heater is the lowest point of your water circuit (in the basement typically) you can use the effects of convection currents to circulate the water? Of course if your heater is not at the...

It's just unimpressive, from all angles and missed its prime by 15+ years. Oh well, maybe version 3 will add some nice enhancements.

Here's some pictures of my power monitoring set up. The graph is a quicky and I noticed some labeling errors as I uploaded the picture. I'm not telling what the error is though. :P I also see I need to increase the scale of the top graph. It maxed out when I ran the shop vac. It shows the kW...

The 8035 and 8036 (8036 offers a lot more information than the 8035) are superior for power monitoring because they do all the calculations locally. You read the modbus registers to get the values. If you don't have a modbus master than they won't do you any good. They are a standard in...

you too - you're preaching to the choir Sorry to ruffle your feathers, but I bet there isn't one person here that hasn't spent money to upgrade and existing component of their system. It's evolution. My wife hates it. I've bought upgrades to things I haven't even installed yet only because I...

you're preaching to the choir

Yes, my thoughts precisely! :P Not to start any friction here, but I know there isn't any standard electrician in my phone book that has the foggiest idea about integration of electrical and home automation/security. Oh the money it would cost if you could find some people qualified to do it...
