I've been using a CX4 with a Smart Plug and an XBee Sensor LT with no problems for some time. Recently I ordered an XBee Sensor LTH to add to the existing network.
The new LTH is causing problems. When it first starts up and associates, it's fine for a short time. The ASSC light blinks three times then pauses briefly, then continues this way for a short time. As long as this is happening everything is fine.
But within a couple minutes the ASSC light on the new LTH will start to blink continuously. At this point the CX4 web interface becomes non responsive. This includes operations not related to the LTH. This unresponsiveness goes on indefinitely (I've waited up to 30 min before taking action).
After, removing batteries from LTH, after a while the CX4 will return to its normal, snappy self. Replace batteries in LTH and the whole set of problems start again.
Ideas? Should I return the LTH for a replacement? Is this an issue with the LTH having newer firmware than the existing nework?
