Once I powered it up, an indicator light was on and flashing orange. I installed the Kasa app and within 2 minutes it was connected and working perfect. It immediately performed a firmware update and continued to work perfect. I was also able to connect it to Alexa without any problem. When its off, there is an indicator or night light so you can see the switch at night. I love this switch and cant wait to install the other two I bought. Love it!
