I've had several P110 energy monitoring smart sockets where the relay has locked up. Usually a couple of taps frees them up. I've taken one apart, and they don't come apart easily and required tape/glue to secure the case again. I found a cover shell to 3D print. I looked at the possibility us using a mosfet but it is too large. I've modified one to have a socketed, user replaceable relay.

I have much older KASA switches that do not exhibit this problem.

Are any of the newer smart sockets better and what are the version numbers and SKU?
