# Aqara Multi-State Sensor P100

Aqara Multi-State Sensor P100 is a direct Matter contact-style sensor when used over Thread, but its more unusual object monitoring pitch belongs to the Aqara Zigbee path. Buy it for simple Matter state checks, not for every Aqara mode to appear in every ecosystem.

## Ecosystem Support

- Apple Home: Supported
- Google Home: Supported
- Alexa: Supported
- SmartThings: Supported
- Home Assistant: Supported

## Best For

- Doors, drawers, boxes, and small openings that need Matter state reporting
- Buyers choosing between direct Matter and Aqara-specific Zigbee features
- Homes with Thread already working near the mounting point

## Skip If

- You need Aqara object monitoring inside Apple Home, Google Home, Alexa, or SmartThings
- You do not have a Thread border router
- You want one setup mode to expose every advertised feature everywhere

## Setup Notes

- Choose Thread if you want direct Matter pairing to Apple Home, Google Home, Alexa, SmartThings, or Home Assistant.
- Choose Zigbee only if Aqara Home object monitoring matters more than direct Matter support.
- Decide on the protocol before mounting because the visible feature set changes by mode.

## Known Limitations

- Aqara says Thread mode offers open and close monitoring.
- Aqara says the richer object monitoring mode requires Zigbee and an Aqara hub.
- The Zigbee-only object monitoring features should not be expected in third-party Matter apps.

## Pros

- Direct Matter-over-Thread path for open and closed monitoring
- Can be used on doors, drawers, pet doors, boxes, and similar objects
- Optional Zigbee mode adds Aqara-specific object monitoring
- No Aqara hub is required for the Thread Matter path

## Cons

- Matter over Thread exposes a simpler feature set than Aqara Zigbee mode
- Requires a Matter controller and Thread border router
- Zigbee object monitoring needs an Aqara hub and is not bridged to Matter platforms

## Two protocols, two expectations

The Aqara Multi-State Sensor P100 is one of Aqara's dual-protocol sensors. In Thread mode, it is a direct Matter device for state monitoring. In Zigbee mode, it leans into Aqara-specific object monitoring through an Aqara hub.

That split matters for buyers. Thread is the right choice if the goal is direct Matter pairing. Zigbee is the right choice only if Aqara Home features matter more than platform-wide Matter compatibility.

## What Matter gets you

In Thread mode, the P100 is best understood as a small state sensor for things that open, close, or move between simple positions. That can still be useful for doors, drawers, pet doors, mailboxes, tool cases, or cabinets.

The unusual object monitoring language should be read carefully. Aqara says the richer object monitoring mode is tied to Zigbee and an Aqara hub, and that path should not be assumed to show up in other Matter apps.

## Should you buy it?

Buy the P100 when you want a flexible little direct Matter state sensor and already have Thread. Skip it if the feature that caught your eye is Aqara's Zigbee-only object monitoring and you expect that same detail in Apple Home, Google Home, Alexa, or SmartThings.
