Can a Kasa smart light switch be grouped with the "Lights" group in Google Home app? The switches only show up under "Devices linked to you" section at the bottom of the list. The device type is set to "ligh (switch)" but do not appear under the lights section when I click the light bulb icon in the top section of the Home app.
Thanks for reaching out. Devices on the Google Home app are categorized by product, so if they are labeled as switch it will not group with the lights. You can try renaming your switches or assigned them on the same room as where your lights are assigned. Check this guide for more information.
Hope this helps.
