I have been a Vera user , all flavors , for more than 8 years now, I have tried Ui1.5.x.x and UI7.x.x ,I have tried the Vera Edge with approx 40 sensors and modules and using PLEG for controlling most all aspects of the Home automation. I found the Vera Edge could not handle all the Automation, tech support worked with me for 3 weeks to try to get the Edge to cooperate . I finally sent it back to where I bought the Unit. I changed over to my Veralite and my Vera3 and split the work up between the 2 controllers. I run Mysensor Ethernet Gateway on both of my controllers, 1 gateway for 2 Veras.
I have Zwave motion sensors,Zwave modules, Zwave dimmer modules, Zwave Honeywell Thermostat and Temperature and Humid sensors that are Zwave. I have Mysensor door/window sensor built with Attiny 85, so much cheaper to build than using
Nano or Pro-Mini I also have Scene controllers built with pro-Mini that control ceiling fans remotely, bedroom lights remotely, Entertainment Centers remotely. You get the Idea. Now nothing is perfect I have had my glitches but for FREE their is no other controller I will use , unless someone comes up with one as reliable and cost effect as MCV.
