I have all of my wiring terminating on 110 blocks, including the keypad RS485 bus for 3 keypads. They are connected to one of the Elk active hubs. While I wouldn't install 66 blocks in any new installation, I don't think that the low-speed RS485 signaling is going to work any different than in...
I think alot of this becomes easier to deal with if you operate the Zigbee radio in "API" mode vs. "transparent mode" so you can explicitly address individual Zigbee radios when you send and receive frames, rather than just treating the Zigbee radio as long, dumb, virtual wire. In transparent...
Anyone notice errors in the frames emitted by the ECM1240 after doing an upgrade to the new version of firmware? I notice that running the Interface Application on the serial connection, I get a frame error with every frame that's received. The data being decoded looks OK, but a cursory...
Can you share your changes? I'll try to merge them into my code base (which has about to undergo some serious updates, when I get the time) and carry them forward.

What about if the series connected CTs are connected to the DUAL and COM inputs? If the CT settings are set as such in the interface program, will the right settings be configured in the ECM-1240?
Beware, you might have a problem with the size of the wire on the 50A branch circuit. I was originally going to monitor the power consumed by my fancy electric double-wall-oven, but found that the conductor was too large to fit through the 40A micro-CT.

I've got an ECM-1240 with the Zigbee radio and the Zigbee/USB dongle. I've written some code to run on my FreeBSD system to talk to the ECM-1240, and is a server that can accept TCP connections from one or more clients. Each client that opens a connection to the TCP port the server process...
If you do the wireless version, you can drop in a repeater or two to extend the range. I would personally be concerned with a very long RS-232 cable, not because of the data rate (though it is single-ended vs. a differential pair, so you'll have to worry about noise being picked up). My worry...
Just to follow-up: It's all working now!
The problem that I had all was due to having the wrong version of the USB Zigbee dongle firmware. While it might not be clear from the Brultech web site, there are two different versions, the repeater version (that I ended up with by mistake) and the...
I just received mine in the mail today, and am trying to get the wireless dongle to talk to the ECM-1240. There's really no documentation to speak of to help you set that up, and screwing around with the interface application tells me I got the USB drivers installed because I can talk to the...
I just placed an order for the "A+/200" product and a USB Zigbee adapter. Has anyone received one yet and can estimate order processing/shipping time?
I too am keenly interested in the protocol documentation, as I need to integrated into my homebrew home automation system. Presently, it...
I've noticed that occasionally I'm getting messages from the Elk M1 (via the M1-XEP Ethernet interface) with an incorrect checksum on some "AS" messages. Usually, I'll see correct messages like:
1EAS000000001111111100000000000E
but every so often, the broken version of this message with a bad...
I've finally made it back out to the site with the funky BR-R1-A board, and my first bit of testing by moving the calibration jumper seems to indicate that the A/D converter is working fine. I got from a reading of 10.23V to a much more reasonable calibration value of 3.45V:

I had a similar problem with my barometric sensor probe, as you can see in this posting a few months ago. Some one suggested a defective sensor, but I haven't heard any other suggestions from HB. Complicating the debugging for me is that the sensor is at a remote location that I've not had a...
