So I got a new router and some (not all) of my Things stopped transmitting their data to the hub. My Things consist of 1 motion detector and 2 general purpose open/close sensors, all Samsung ST. After the new router, only 1 o/c sensor was registering changes, although the hub claimed it could see all 3.
Based on a different thread here which suggested I should delete the location and redo it, I went ahead and started over with a new location. However, now I cannot detect any of the Things (although my Droid does show up as a presence sensor). I have tried doing both a power cycle and reset on the hub to no avail. The LEDs are solid green and switch to blinking when it tries to search for new Things, but it never finds any.
