...more stuff, more questions. The Composite Class module and the garage door example are very interesting. I'm having two problems though. When I try to bind an Elk output to the garage door's GarageDoorOpener, it seems fine. But when I look at in the browser, I dont see the opener or any...

Thanks 123. It's a lot to digest, but it seems to be just what I was looking for.

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 was just being conservative. If you were to use 1% or better precision resistors you could probably push it further. I havent played with the A/D conversion in the Elk so I dont know how much slop there is there. Things could change based on temperature or battery vs AC power. Either way...

I've got nearly 60 UPB switches, mostly SA US2-40's. I am very happy with the purchase. UPB is pretty rock solid. The number of switches doesnt really matter. The upstart tool let's you check out signal strength to and between devices. Unless you have an odd source of intermittent noise...

Voltage levels sound like a great idea for applications like presence detection where the response time of the system is not important. In my case, when a user presses the button, they expect a response right away. In the Elk there are two ways to trigger a rule in response to a zone change...

It's an attempt to save on wires and input zones. The most straight forward approach would be to connect each momentary rocker to two different zones. One zone would keep an eye on the top of the rocker while the other would monitor the bottom. Rules could then be defined to activate on the...

I was thinking the same thing. I was hoping someone would confirm it though. It sure sounds like a bug in that a transition is happening. I was hoping to keep it simple. And yet another is to use a second zone for each switch. If it was just one switch I'd consider it, but have three of...

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...

I gave a couple of these a try. I wired one up, turned the sensitivity all the way up, and walked around the garage with it. It worked quite well. There is an LED to indicate detection so that made the experiments easy. If it's a car you are trying to detect the range is better than the...

So if my math is right, the floor 100" away (say) will read 1.0v with the Elk reporting 1/12*256=21 while a car roof 40 inches away will read .4v/12*256=8. Is the Elk's A/D converter stable enough at low voltages to consistently notice a .5v difference? I'd think that it would be but I havent...

I think both the pressure sensitive mat and the ultra sonic sensors are great ideas. I looked for the mat at Harbor Freight... seems like it would take some work to get it ready to be parked on. With easy access to the rafters, an ultrasonic sensor would be perfect, out of the way, easy to...

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...

Is flow control disabled? If so, try enabling hardware flow control. If you are using hardware flow control try disabling it. ...other than that, I've got nothin'

Just a wild guess, but are the flow control options the same in both cases? Try turning off flow control. Other stuff to check... are you using the same rs232 cable in both cases? If not a pin could be broken. have you tried the edgeport with a different rs232 device and found bi-directional...

One of the cool things about the UPB protocol is that every packet sent contains the ID of the source device. So the data is there. It's just a simple matter of programming ;) Multi-button switches like the US2-40 are a little trickier because they dont indicate which button was pressed...

Now that's very cool. It's been about a week now and I am really starting to like premise. I'll have to take a look at what you've done, but the way you describe it makes me think it might not be what I was hoping for. It's not about the light being on. That can happen for many reasons, like...

I havent added a device but I would like to. The download that 123 pointed me to already knew about the US2-40. Oddly, the older driver knew about the SA UML but the newer one is calling it a WS1D6. I have a couple of SA US22-40's and a couple of PCS FMD2's that I'd like to be to control. I...

Thanks 123, That did the trick.

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