I put a bunch of smart light switches in my house about 5 years ago. Two of them have failed in the past year and I reverted them back to dumb switches. I'll probably do the same as they continue to fail over time. I found I rarely use the smart features to their full potential. It helps that my house is built to all the modern codes, so I have switches at convenient places and really only use the "smarts" for table lamps and outdoor lighting.
