thank you all for your inputs. My home is brand new, I have not looked at my three way switches yet, but I'm pretty sure they will have a neutral wire and that should not be a problem. As for the echo plus hub, I could return in but our have has three bedrooms and a den, so I can use it as an Alexa control spot anyway. So my set up is I have three bedrooms and an office/den. I will have ceiling fans in all the rooms eventually, including the great room. Our ceilings are 9-6 so a ceiling fan is way up there and yanking a pull chain is not an option.
I thing the Wink hub will help me connect the fan speed controllers fine, as it supports Z-wave, Zigbee, and a whole bunch others. Im going to try that Smart Switch 5A- Wifi Remote Light Switch Universal Module Relay, from amazon and see if it will fit in my ceiling fan light kits. If it does that, then I have a cheap, $11.00 light kit fix so Alexa can control the ceiling fan lights. IF I can just get my ceiling fans automated that will be a big step.
THen I have to check into the smart thermostat, the Nest and make sure it work's with my unit and let Alexa control that.
