I bought my first light switch (Ezex C2O model). I only bought one because I wanted to make sure it works well before replacing all the switches in my house.
I bought this model because it doesn’t need a neutral wire (no neutral wires in my house) and because it appeared in the SmartThings supported device list (I didn’t want to be bothered with any custom device handlers).
Installation and setup was easier than I expected. Seemed to be working great, and no flicker or other weirdness that I read about with no-neutral switches.
BUT… SmartThings doesn’t update the status when I use the physical switch. For example, if I turn on the light using the physical switch, it still appears Off in SmartThings. To turn it off using SmartThings, I need to click the button twice. Once to “turn it on” (which does nothing because the actual light is already on), then a second time to actually turn it off. This is annoying, and also makes it useless for automation. If I set an automation to turn off lights when I’m not home, it won’t work because SmartThings thinks the light is already off if it was turned on using the physical switch.
Is this normal? (I’m guessing no)
What can I do about it? Can I submit a bug report somehow? Should I be submitting it to SmartThings or Ezex?
Can anyone recommend good SmartThings-compatible switches that don’t require a neutral wire and work with 220V?
