Z-Wave

I am getting started on Z-Wave and looking for a controller. I see there are some USB sticks and then a regular controller. Perhaps the controller is best as it would have Wi-FI- so could use Alexa and an cell phone app.
I bagged up my X-10 and sent it to Good Will

It is an RF communications and control protocol (including physical layer) used by some Smart Bulbs, Smart Thermostats, etc., and their associated controllers. Using an optional internet bridge it allows control over arbitrarily long distances..
It seems to be winning the battle against competing protocols for interoperability.

I've been using a Samsung hub for a few years. No complaints. It does both Zwave and Zigbee. One of the cool things about both of these protocols is that each hardwired device (includes plug-in devices) also acts as a repeater, so while the distance limit is 100 feet , devices can be a few hundred feet from the hub itself by virtue of the repeaters.

The practical unit to unit range indoors, particularly for Zigbee on WiFi frequencies, can be less than 40 feet, depending on line of sight obstructions. But the mesh network can still extend the range past 100 feet. Zwave limits the mesh to 4 hops.

I didn't know that about it being limited to 4 hops. It's pretty interesting to see the route it takes sometimes.
