I’m using Z-Wave dimmer outlets I found super cheap on eBay.
They REALLY need to be close to the hub JUST to initially add them to the network.
But then, the mesh networking takes over, and I have one of these in the far backside of my house, outside, in a metal box, controlling the garden lighting system. No problems at all!
Mesh networking is great!
BTW: This is why I am VERY concerned about alternative networking protocols such as BLE (Bluetooth Low Energy), which are in the “Motes” product. The range of these must be very limited. They are not plugged in, and, as far as I know, don’t have any mesh-networking or signal-repeating. There are workarounds (multiple hubs as repeaters?)…
In short, I’m grateful SmartThings works well with Z-Wave and presume that ZigBee mesh will also work well (though I’m hoping for expanded support of XBee too; and integration with LAN WiFi means that if you have a strong WiFi (technology always improving and ways to repeat signals, etc.) then IP devices will also be promising).
