For several years I have been using z-wave controllers from Mi Casa Verde / Vera Control, Ltd. to manage and control my z-wave devices. For nearly 3 years I used a VeraLite and was mostly happy with it. Then its z-wave module failed suddenly, never to work again. I replaced it with a VeraPlus last November, but quickly came to dislike the new device. I have to power cycle it every month or so, as it goes unresponsive to network packets. Once, it even took down my entire home network somehow. All local and internet communication just gone. Even DHCP wouldn't work. That was a pain to trace back to the VeraPlus, because it would only kill connectivity after being plugged in to the LAN for about a minute. Power cycling the VeraPlus eventually fixed it, but understandably I no longer trust the device and sooner or later I am going to replace it with something else. So I would like to know if anyone else has a z-wave controller they really like. I was thinking about an Aeotec Z-Stick Gen5 (USB, $45) connected to a raspberry pi, running Domoticz or something. But I am open to any suggestions. This is going to be a complex transition and I'd rather not find out halfway through that one of the things I did with Vera won't work with the new system. My requirements are: * Work with ImperiHome mobile app * No forced "cloud" integration. * Wired ethernet * A simple http API for integration with other systems * Needs to work with a wide variety of z-wave devices. I have power outlets (some with energy usage reporting), dimmer switches (one needs its ramp rate reconfigured by the z-wave controller), and even a drapery motor and a door lock (which I have configured to lock every night at midnight). * Easily back up and restore the entire z-wave network configuration to a new device in case of a hardware failure.
