I am upset the wemo wall switches requires a neutral wire. I would rather have wall switches instead of connected bulbs, otherwise, whenever guests and other family members use the switch to turn off the light, you have to manually turn it back on before you can use the echo. I do use tcp connected bulbs with the wink for dimming using the echo.
I know it is going to cost extra but maybe a combination of wall switches and connected bulbs that can dim may be what is needed in your case.
