Xfinity centralite 3400 in the UK?

Unfortunately, I don’t think this is possible. It is a passive device that is not powered on most of the time, and only powers up when you interact with it. The benefit is great battery life, the downside is that it is not designed to respond to events; only to generate them.

OK i can understand that, what about when arming or when a code is wrongly inputted?

According to the technical manual for the device (https://www.zipato.com/wp-content/uploads/2015/07/wt-rfid-Zipato-Mini-Keypad-RFiD-Z-Wave-User-Manual-v1.4.pdf) it is possible to set up the way the device beeps to indicate when a code was wrongly inputted (at least I think that’s what it’s saying - it’s a bit hard to make sense of). See the “Sound Notification” section in that PDF if you want to see if you can make more sense of it than me :slight_smile:

Unfortunately, I was never able to make this work. I noted this at the bottom of the readme on the github page for the device handler: https://github.com/seanblanchfield/smartthings-zipato-rfid
It was two years ago, but I do remember trying hard to get my Zipato to respond in any way to the “sound notification” configuration commands, but I couldn’t get it to anything other than the default beeping when you arm/disarm.

I ended up providing feedback by setting up a voice announcement to play on my smart speakers whenever the front door opens in away mode, and a confirmation announcement when the alarm is successfully disarmed. I also indicate the alarm status by temporarily changing the colour of the Hue lights in the hallway whenever the front door opens.
