I connected my Piezo Buzzer to my Alarm Panel Add-on board as shown on the "Wiring a Piezo Buzzer for Door Chime" installation instructions.  At first, I believe I was hearing a sound when I opened my door.  To test the range of the sound, I started walking around the house and pressing the beep button on the SmartApps panel to trigger the sound.  It was working like that for a while but then there was no sound when I opened any door.  At first I had it wired to the OUT and GND pins on the board.  Then I moved it to the OUT and GND on the terminal block and then onto terminal 4 and GND.  Nothing was helping.  Now, I can't even get the beep sound when I put it back on the OUT and GND pins on the board.

I'm still getting signals when I open or close any of the circuits but the buzzer is not working at all.  I did enable the Low Level Trigger via the SmartApps and verified the buzzer is still functioning.

Not sure what else I can share in this message but any help would be much appreciated.

  • I'm having the same problem.

  • I removed the configuration and reinstalled everything.  During the re-configuration, I put the buzzer on the main Alarm Panel instead of the Add-on.  I still don't get a beep when I open doors or windows but I can now enable the buzzer through smartthings and hear the beep.


    Still trying to figure it all out.

  • You are using the smart lighting smart app right? I was struggling with this earlier until I found out that you had to set it to go off with open/close sensors in smart lighting!
  • I eventually figured out the need to configure it in smart lighting as well.  But, in the interim, the piezo suddenly was not visible to Smartthings as a switch.  I tried rebooting the konnected board, which did not help.  I have my piezo connected to the out, so I can have it wired upstairs near the old Vivint panel.  I was able to re-list it as a momentary switch on konnected, and could then be found again.  After that, I was able to see it again in Smartthings and configure it in smart lighting to activate with doors are opened.


    Not optimal, in my mind, but working for the time being...

  • I'm not sure what you mean by the Smart Lighting app but I'm certainly willing to give it a try.  Is there some more details you could provide on your solution?

  • in the Automation tab of Smartthings:

    1. Tap SmartApps
    2. Add A SmartApp, then 
    3. Lights & Switches, then 
    4. Smart Lights, then 
    5. Which Device to Control, check the piezo, then
    6. How to trigger the action, check open/close, then check the sensor you want to beep, etc
    Hope that helps.

  •  The piezo connection is a bit confusing (mainly on how it appears in SmartThings). As per https://docs.konnected.io/security-alarm-system/wiring/door-chime/ there are 3 ways. My question is how to appear it as a buzzer based on each way.


    1. Connect to OUT and GND on Add-on card (use the female-female connector): I see a ALARM/OUT option to configure. Is this to be configured as a beep/blink switch in SmartLights?

    2. Connect to OUT screw terminal and G (use the female-male connector): Same question as above.

    3. Connect to a Zone: I did that as a zone on the add-on (for now). Configured it as a beep/blink switch.


    So, confused on using the first 2 configurations.

    Also, people are mentioning customizing beeps, # of beeps, low-level trigger etc. I do not see those options. Can someone tell me the steps to these options? Thx.


    NOTE: I accidently chose ALARM/OUT on the Add-on to configure and gave a name. Now i cannot delete the name and still save the config. I cannot remove the ALARM/OUT entry so why this force check?


  • Not 100% sure I get your questions but let me try to answer them anyways. 


    With the female to female connectors, you would connect directly to the pins on the left edge of the add on board (positive to the 5V pin, and the other to the ground (GND). 


    For the male to female connectors, they're mainly for hooking up the buzzer to one of the zones and one of the grounds (the screws on the bottom). Again, the positive will go to a zone, and the other to the GND. 


    For the customization, you're going to have to locate the piezo buzzer (or whatever you named it) under the tab my home. After you tap on it and enter the piezo screen, you can click on the settings cog on the top right to customize the beeps. 

  • The piezzo is polarity sensitive too, it didn't work for me at first because i had the wires swapped LOl
