This tiny electromagnetic sounder makes a high pitched "beep" sound when 3V is applied. It can be wired directly to an output pin of the Konnected NodeMCU board and controlled using the Konnected Beep/Blink device handler. You can use this to replicate the door chime capability of many wired alarm systems.
What Does It Sound Like?
Play the sample below:
The number of beeps, beep duration, and pause between beeps are all customizable. However, the tone/pitch of the beep cannot be adjusted.
Not good for a door beep
Piezo works fine but I would have liked it to be louder. I installed additional piezo sounders in old keypad locations and the sound is scratchy. Perhaps noise is picked on the wire between the Konnected Panel and the sounder. Working in Smartthings the beep is very delayed from when doors are opened. Worse is the sound not does not turn off if beep is programmed for less than 5 seconds but I don't want a 5 second beep. For now, I am not using them. Sounder is fine but not useful for my intended purpose.
Died within 1 year of install
While these are fairly cheap, disappointed I had to purchase another one since the first stopped working about a year after install.
worked like a charm until it didn't
I have a Home Assistant integrated Konnected setup. The "Buzzer" configuration was really easy. The volume of the buzzer is a bit on the low side. But after 3 or so days later the output type ports got "unavailable" on the device (including the buzzer), though all sensors still worked. I had to remove the integration, reset the konnected panel and start all over again. Monitoring the situation now
Door chime programming
Im having a hard time getting the door chime to work when our back door opens. Seems like it should be easier then what Im finding online. Maybe its me and my lack of knowledge with samsungs app interface. The rest of the door and window sensors work really will and happy with the Konnected products.
Great Door Beep Device
I was looking to replace the door beep from my traditional alarm system and this did the trick. Using the existing wires going to my 3 old keypads I was able to install the piezo inside each of old keypad housing. This way can have the classic door and window beeps.
