If you want to see the install process, go to YouTube and search for “Installing a WEMO Light Switch reviewy mcreviewface”. It’s easy, with even just a dangerously small amount of DIY know-how.
Works great; have it set up with my Google Home, as well as the timers built into the WeMo app. No worry about expensive “smart bulbs”, no problems with shoddy manufacturing and bad specs for sizing, and no issues with connectivity.
If you’re thinking about making your home a little smarter, and don’t need a colour changing bulb, I would highly recommend these over a smart light bulb.
