Frequently Asked Questions

Why is Alexa not turning on lights?

Alexa may fail to turn on lights if the “lights” option in Alexa’s “Devices” is turned off, the power supply connected to the Alexa Echo speaker is off, there are some problems with the Wi-Fi source. If you haven’t set the skills and scenes correctly on the Alexa or companion apps, you may notice another problem with Alexa saying: “I don’t know how to set light to that setting.” In the last case, it’s just a matter of trial and error. You need to give it a few days for Alexa to get used to the scenes you created.

Can Alexa turn on lights away from home

Can Alexa control multiple smart lights?

How do I reset my Alexa lights after a power outage?
