# SONOFF AirGuard PM2.5/PM10 Matter Air Quality Monitor (SAWF-07P)

SONOFF AirGuard SAWF-07P is a useful Matter monitor when smoke, cooking, or filtration is the question and a visible particle reading should also reach a smart-home app. Its platform support is unusually well documented, but Alexa gets less data than the other ecosystems and eWeLink keeps the history and alert settings.

## Ecosystem Support

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

## Best For

- Rooms where cooking, candles, outdoor smoke, or an air purifier make particle trends useful
- Wi-Fi Matter homes that do not want to add Thread infrastructure for another sensor
- Apple Home, Google Home, SmartThings, or Home Assistant users who want documented particulate, temperature, and humidity values

## Skip If

- Carbon dioxide or ventilation is the main air-quality question
- Alexa must receive numeric PM2.5 or PM10 concentration and humidity
- The monitor needs to run without a cable or mount flat against a wall
- Historical charts and alert configuration must work without eWeLink

## Setup Notes

- Place the monitor indoors on its desktop stand with the intake and exhaust vents uncovered.
- Provide continuous 5 V, 1 A power over USB-C and reliable 2.4 GHz Wi-Fi at the final location.
- Add the monitor from a compatible Matter app for the shared ecosystem path, or use eWeLink when history, exports, thresholds, and alert settings are required.
- Confirm the particulate value, temperature, humidity, and automation conditions exposed by the chosen platform before relying on an air-cleaner routine.

## Known Limitations

- SONOFF's Matter table shows numeric PM2.5 or PM10 concentration and humidity in four ecosystems, while Alexa receives only an air-quality level and no humidity value.
- Humidity in Apple Home requires iOS 26 or later according to SONOFF's product page.
- The local controls switch the displayed detection mode between PM2.5 and PM10; verify that the selected mode matches the particle problem being tracked.
- One history paragraph on the current product page mistakenly says CO2, while the exact SAWF-07P support page documents PM2.5 and PM10 history.
- Matterhome has not tested commissioning, sensor accuracy, alert behavior, or ecosystem automation support.

## Pros

- Shows PM2.5 or PM10 concentration, temperature, and humidity on a local display
- Pairs directly over Matter without a Thread border router or SONOFF hub
- SONOFF documents particulate, temperature, and humidity readings in Apple Home, Google Home, SmartThings, and Home Assistant
- Includes a local buzzer and color indicator, plus one year of history and export through eWeLink

## Cons

- Needs continuous 5 V USB-C power and a stable 2.4 GHz Wi-Fi signal
- Alexa receives an air-quality level and temperature rather than numeric particulate concentration or humidity
- Historical data, exports, thresholds, notifications, and alert schedules remain eWeLink features
- Cannot be wall mounted without obstructing the rear air vents and affecting measurements

Buy SONOFF AirGuard `SAWF-07P` when the room has a particle problem you can name. Cooking, candles, outdoor smoke, and air-cleaner performance are sensible reasons to put its PM2.5 or PM10 reading on a desk and into a Matter app. Stale air is a different problem: this model does not measure carbon dioxide. Matterhome has not tested the monitor, its readings, or its alerts.

## Put it beside the problem, not against the wall

AirGuard measures `70 x 103 x 26 mm` and shows a particulate concentration alongside temperature and humidity. SONOFF rates the particulate accuracy at ±10 µg/m³ from 0 to 100 µg/m³ and ±10 percent from 100 to 500 µg/m³, with updates every two seconds. These are manufacturer specifications, so compare the monitor's response before and after the room's actual source or air cleaner runs rather than treating one isolated reading as proof.

The rear vents decide where it can live. SONOFF says the intake and exhaust must remain uncovered and warns that mounting the unit against a wall can affect measurements. A shelf or desk with open air around the case is a better fit than a narrow gap behind furniture.

The monitor needs continuous 5 V, 1 A power over USB-C, plus stable 2.4 GHz Wi-Fi. It is not a battery sensor to carry between rooms. Pick the final location before pairing so the cable, Wi-Fi signal, airflow, and particle source all match the job.

## Four full data paths and one reduced path

SAWF-07P pairs directly with a Matter controller over Wi-Fi. It does not need a Thread border router or a SONOFF hub. SONOFF's exact support table documents the following data and voice-query behavior:

| Ecosystem | Particulate data | Temperature | Humidity | Voice query |
| --- | --- | --- | --- | --- |
| Apple Home | Numeric PM2.5 or PM10 | Yes | Yes, with iOS 26 or later | Yes |
| Google Home | Numeric PM2.5 or PM10 | Yes | Yes | Yes |
| Alexa | Air-quality level only | Yes | No | Yes |
| SmartThings | Numeric PM2.5 or PM10 | Yes | Yes | Yes |
| Home Assistant | Numeric PM2.5 or PM10 | Yes | Yes | Not documented for this model |

Alexa is the compromised route. An air-quality level may suit a quick voice check, but it is not the numeric concentration needed for a precise threshold. Apple Home, Google Home, SmartThings, and Home Assistant have the stronger documented data path.

The table does not promise every tile, trigger, notification, or history view in every app. Commission the monitor in the platform that will run the routine, then confirm the value and condition before an air cleaner depends on it.

## Decide where the history should live

The screen, color indicator, and buzzer work without opening a phone. eWeLink adds thresholds, push notifications, indicator brightness, scheduled do-not-disturb periods, and up to one year of PM2.5 or PM10, temperature, and humidity history with export.

Those are vendor features. SONOFF does not say that Matter transfers its history, alarm configuration, or air-quality advice into another app. Use Matter for the current readings that the selected ecosystem exposes, and expect to keep eWeLink for firmware, history, thresholds, and deeper alert settings.

The exact `SAWF-07P` carries store SKU `6920075743265` and is available from SONOFF's United States, European, United Kingdom, and global storefronts at about $40, €41, or £36. [SONOFF AirGuard CO2](/devices/sonoff-airguard-co2) is the family alternative when ventilation is the real question. [IKEA ALPSTUGA](/devices/ikea-alpstuga-air-quality-sensor) is the Thread alternative when one sensor should cover both carbon dioxide and particles.

Before checkout, choose the particulate mode that matters, identify a powered desktop position with clear vents, and check the receiving ecosystem in the table. If the required destination is Alexa with numeric PM and humidity, stop there. This hardware and platform combination does not provide it.
