How To Turn on Lights With Alexa
I use Alexa to turn on my lights. We have set up our house to have Smart Lights or Smart Switches in every room. We can turn the lights on or off anywhere in the house. This requires using Smart Things or Hubitat to control.
“Alexa, turn [name of room] lights on”
“Alexa, turn [name of room] lights off.

You can also group lights together using the Smart Things or Hubitat. We have group the downstairs lights together. When we go to bed, we just say “Alexa, turn downstairs off”
