The ability to easily integrate different devices with one app was great! I liked that it has multiple languages available, as well as being able to add more if needed. It's super easy to use once you get past your first few minutes trying to figure out how all these things work together in harmony. We used this software primarily because we were looking into connecting our thermostats wirelessly using Z-Wave technology versus having them wired up directly through an ethernet port or power line connection. This made integration much easier than working with other brands/devices without similar features. There wasn't anything negative about Evothingz at this time; however, there are some small issues which could be resolved when updating future versions - such as not allowing users to connect their own home automation hubs via Bluetooth instead of only accepting those from authorized vendors like Home Depot etc. If you're interested in integrating any type of device then look no further, they have everything covered.
