There are plenty of reports of this problem and you keep saying this is a hardware issue and needs to be handled under warranty but how can 8 devices that work fine all suddenly have the same problem...

If this isn't added soon then I will have to buy from another manufacturer as I need to be able to control devices based on electricity price. I don't want a remote switch I want a smart switch!

@Stella.Q This short time is taking a while! It's a shame I like the product but without being able to be integrated with other systems they are not smart
