Hi Bob,
You can send the device to me so I can test to see if I get the same response…or if you can find a way to isolate the EZX10RF so it can’t receive signal by removing the antenna or putting a tin can around it and see if that stops it, you can better tell if it’s RF interference that is being interpreted as a bright command or something internal that would be generating that signal.
Our engineer says that it’s next to impossible for it to generate the signal by itself…so he suspects that there is some stray RF signal that the EZX10RF is seeing as a bright signal.
