Don't spend any money on hubs. (You don't need one. No one does. ) TP-link has Wi-Fi switches (~$25) that work with Amazon Echo. TP-Link makes smart switches, dimmers, and 3-way switches. TP-Link smart switches come in colors other than white. TP-Link is very reliable. A SmartThings hub costs ~$100. Homeseer costs $150. Why would anyone ever have two hubs? For $110 you can get an echo dot (~20), 3 TP-link switches ($75), 3 Lutron faceplates (~$10) and a small spool of AWG 12 or 14 wire in white (~5). Once you set up the first TP-link switch, Echo will auto-discover the others - no set-up. I use We-Mo (~$45) dimmers, but they are about twice the price of TP-link. In my office and my wife's, I have TP-link switches because the faceplates go better with black switches than with white. I use Lutron's faceplates because the standard plastic or steel faceplates don't are too shallow for smart switches. In my house, the neutral white wire is in the switch box. But I need to run a neutral to the smart switch from the neutral bundle. A 6 inch piece of AWG 12 or 14 wire does the trick.
