Here’s the setup with my MyLatestAqaraMulti-State Sensor P100 might be useful for a few of you - a simple retrofit to solve an old, annoying problem: missing the doorbell whenever I’m in another room.
I would have loved to install one of the great smart video doorbells Aqara offers, but since I live in a rented apartment, the landlord unfortunately didn’t allow it. Rather than replacing the existing intercom or dealing with invasive rewiring, I attached the P100 directly to the back of our existing chime’s speaker housing (held securely in place by a simple rubber band).
In the Aqara Home app, I have it running in Object Monitoring mode to pick up vibrations:
Trigger: Vibration detected by the P100 when someone rings the doorbell.
Actions: It immediately triggers a custom ding-dong chime on my Hub M3, and bridges across to Home Assistant to broadcast the chime to my Google Nest Hub as well.
Now, whenever someone rings at the front door, we get an instant, clear chime across the entire apartment without modifying the building’s wiring or missing a single delivery.
One feature request for the Aqara team: Right now, vibration detection is only available when paired via Zigbee in Object Monitoring mode. It would be fantastic if the P100 could also expose vibration events natively over Thread / Matter rather than being limited to open/close or Zigbee only. Really hoping a future firmware update brings this capability!
Hello, thank you for your suggestion. I think it is a very good usage scenario. It is worth mentioning that at present, your demand can be realized by switching to the Zigbee protocol with either open-close mode or the object detect mode, both of which support sharing vibration as an presence sensor to the third party with the supported Aqara Hub. Would be worth trying and looking forward to your feedback!
Hi, it seems that you are already a user of aqara hub. I am curious, why you prefer to use vibration function on thread instead of zigbee firmware. Is there any special reason besides the need for a Hub?
Hi @ming_wen, thanks for reading the feedback. Do you mean that if I connect the P100 to e.g. an M3 over ZigBee and then share it via Matter, the exposed Matter device should also have the vibration sensor? If so, that’s not the case for me unfortunately anymore. That used to work for a brief while but a M3 update removed that functionality unfortunately.
What is possible though and how I work around this limitation is to use the Signal and Scene Sync feature. I’d expect not users to not find that advanced feature though.
