greginkansas: @ take a look at www.anarduino.com/miniwireless/ this is what I am using for all new nodes --Papa: Greg, I am looking at the anarduino miniwireless at least for future light switch nodes, but I probably won't be able to get to this for a couple months. Have you used the miniwireless to trigger a relay? If so, which relay & could you directly connect the arduino digital pin to the relay's DC input or did you need to use a transistor to help?Same chip as a UNO as far as I know. I still had some relays from years ago with 5V 20ma windings so no transistors. I have some X10 stuff and am getting more Inseton modules so I use them for 110V stuff. My MiniWireless outputs so far have been using motor modules, L298 I think

Papa, Computourist, Greg,
Apologies for the delayed response. I got busy and didn't get much time to play on this until last week.
Finally I was able to identify the issues that were resulting in erratic behavior.
There were multiple issues- 1. Node power cable that was supplying 12v was very thin, perhaps 30awg. 2. There was a short circuit in my soldering. Two pins were soldered together. Typically I do a continuity test for adjacent pins, but for some reason I guess I didn't look at this very closely. 3. In my gateway setup, I had kept the USB cable connected to the Uno and other end of the usb was open. For some reason, that open usb was below the UNO and causing a short in the gateway.
After fixing these issues in the listed order, the communication between the Node and Gateway started working normal. - Only handful of messages were getting lost. I would say 1 in 20 messages, which is a good and acceptable ratio - Messages were received less than 100ms. Some took 20ms and some 80ms. Earlier the message were taking anywhere between 100ms and 5 secs.
Just wanted to share the learning with the group.
Sam

It seems like most of the communication issues are not a strong power supply or bad wiring. Some give up or we do not hear from them any more. Thanks for letting us know.

Yes, Sam, thanks for the update. Your account underscores the need to check connections as we assemble & develop good troubleshooting methods for glitches.
