I have three ECM-1240's watching over my breaker box. One channel monitors the load on the way into the breakers, then I have a CT on each of the 48 circuits leaving the box. The ECM-1240 Engine software has a cool feature where it subtracts all of outgoing loads from the incoming load and...

I just finished up my upgrade from an ECM-1220 to three ECM-1240's. I couldnt quite decide how I wanted to map my 48 breakers onto the 21 available channels so I was looking for an easy way to change things during and after the install. I thought I'd take a chance on using a 50 pair "66 block"...

I've recently had an awning installed over the back deck and have already connected the somfy dry contact interface to a couple of my Elk's outputs. Now, I'd like the Elk to know if the awning is opened or closed. I am sure I could mount a magnetic security contact somewhere to detect when...

I've been playing with logic diagrams lately trying to do a thermostat setback. Now that it's done Im pretty happy with the way it came out and how easy it was to make it happen. Two thing's I've noticed that were a bit odd. It seems there is no way to directly specify a time interval. I...

When looking at objects in the builder I cant help but notice the field named "language" on the scriptlets. This might imply that the language used is configurable somewhere. My guess is that any of the registered scripting languages would work, but I cant find where to make the change. Has...

I am trying to get started with scripting in Premise. I've been looking for just the right example and just the right task to get me started. I noticed that the beam sensor in the garage that indicates the presence of a car doesnt keep the garage "occupied" after the timer expires. The sensor...

I have a zone defined "non-alarm/EOL supervised" and an automation rule that should trigger whenever the zone becomes shorted. I can fire a rule on the transition from NOT SECURE - OPEN --> SECURE, but the transition from NOT SECURE - OPEN --> NOT SECURE - SHORTED doesnt trigger the WHENEVER...

What's the best way to determine whether a parking space is occupied or not? In particular, I'd like to know if there is a car in a stall in the garage. The sensor needs to interface with my Elk, so a dry contact output would be ideal. The driveway sensors I've seen all seem to imply they...

I was a bit surprised the UPB driver doesnt seem to support SA's US2-40. Am I missing something?

Up until recently, I'd been happy with the automation rules I've been using in my elk. After a recent firmware upgrade, I had to restart the system. This led to my garage door opening.... and closing again. So now I need to question my understanding of things. I traced the problem to a rule...

I've been playing with sending commands to my elk via the tcp connection. It's all working great and does what I'd expect. Except for one thing. If I issue an "sw" command, the word is never spoken. It doesnt matter which word I request. I've tried quite a few including the one in the...

I've got most of the pieces... enough to get usage data from the device. But, I know it can do more. Does anyone have the complete protocol spec? The Brultech docs I have all trail off at the end with a promise of future completion.

A few weeks back I received an HA7Net to use for monitoring my oil burner. At first I was quite pleased. I was able to poll all 12 sensors at a rate of about 1 per second. Not great, but mostly good enough. Then I noticed that after getting a few readings, the device would reboot itself and...

I'd like to use a 1-wire network to monitor my heating system. The temperature sensing seems easy. However, I'd also like to monitor run time on my burner and circulators. A CT and something like the HVAC monitor board are almost what I am thinking of, but if I understand it correctly, the...

I've been looking for a "user interface" to my irrigation system but havent found much of interest. The ECXTRA seem oh so close. The idea is that I want a "normal" looking controller out in the garage, mostly for manual override use and use by folks other than myself. Behind the scenes, the...

I have two garage door openers. The newer one is the one I expected problems with. Turns out replacing the lighted button with an Elk relay is no problem. A project for another day is use a couple more relays along with the capacitors from the original button to control the lock and light...

Has any one tried transmitting from an RFXCOM to a Powermid receiver as a way to get IR in to the room? How about the other way... is it possible to 'learn' IR codes by having the RFXCOM listen to the Powermid receiver? It seems that the non north american version of the Powermid uses 433mhz...

I've read the docs a couple of times and am still having trouble getting my mind around how to use two M1DBH. The instructions are pretty clear when it comes to doing home runs from all devices, however, I'd like to have two "homes". The first is at the panel itself and the second is out in...

I really doubt I am the first to think of using the TPMS system in my car to determine when it has arrive or is leaving from the garage. But, I've searched the interwebs a bit havent come up with much. Can RFXCOM decode the signals? How about some other receiver.

I've got a couple of window A/C units that respond to IR commands. I'd really like to control them with my Elk but am at something of a loss for how to go about it. What can I connect to the Elk that will learn and generate IR? What's the best way to get the IR into the rooms that need it?
