Samotech 323 Driver or Hardware problem

Hi there.

I have a slight dimmer problem with my Samotech 323 ZigBee dimmer.

I've noticed that when I physically turn the dimmer on (by pressing the button) then the device within the app doesn't recognize the dimmers state as being on. Only when I alter the brightness by turning the dimmer (after turning on by pressing) does the state update to "on". I've tried the following 3 drivers but they yield the same result:

  • Generic ZigBee Dimmer
  • RGB Genie dimmer
  • ZigBee generic dimmer (with presence)

NB, the off command and state is recognised in the app once the button is pressed to the off position but not the on position

My use case is that upon physically turning the light on, I want an action to occur but it won't because the hub doesn't seem to recognise the switch has been turned to the on state.

Very odd that turning off is flawlessly recognised by the hub. I appreciate this may be a driver or dimmer hardware issue, does anyone know which one is at fault. Please help.... Appreciated...Stu

Is it this one?

Can you post the device model, manufacturer and application version as shown on the HE device details section?

Hi @kkossev thanks for taking the time to look at this for me. Yes, this is the device in question. Here's the details as requested. :crossed_fingers:

@kkossev, I have another 4 of these which I bought and installed last year. None of these suffer from this issue. When I've looked closer, they have a different model number and also a different firmware. I assume this is the issue. It seems odd that a newer version works in a less effective manner. Is there any way I can repair these do you think? See info below from my older working model.

Thank You @kkossev, I now know the cause which is very frustrating. It would appear that the model variant of my SM323 has a software bug or even dodgy hardware. See this post Driver dilemma - Samotech SM323 dimmers - #4 by stueyhughes
