I have had enough with the lack of support and answers to my questions/concerns. The changes and updates recently made and the focus more on Nest and/or garage door opening compatibility instead of Amazon Echo and Linear devices has gotten me all wound up. I have several Wink Bulbs on a Wink hub just so I can use my Echo to control them. I use two apps now to operate my devices, with 2 (Linear FS20z-1 & WD500Z-1) not working properly. I have to continually remove and re-add these two switches, only to be frustrated when I cannot connect again. These 2 particular devices are located in my garage, which does require my A+ to communicate through 2 walls and across a small patch of my back yard. However, my A+ has no problem at all communicating with my Aeon plug located in my shed even further away. I have addressecd this issue many many times to no avail. I understand Securifi has stated they are doing their best, but addressing things that the average user does not care about has convinced me to spend yet more money and buy a Smart Things Hub. It is compatible with my Echo and supports all of my devices. I now have an over-priced, over-hyped WiFi router in my home.
