Sensorand fumes - Xiaomi Aqara - Frontale


The Honeywell smoke detection sensor of the line Xiaomi Mi Smart Home (or of the line LUMI Aqara Smart Home Automation: same name, same characteristics, same cost) is a small radio component ZigBee of about 10 cm. of dedicated diameter to the detection of fumes in the environment, therefore of possible fires. This device is mounted horizontally on the ceiling or vertically in its own prosolidarity, where for theappgrease the combustion fumes they tend to accumulate in the event of a fire. The device is distributed by Xiaomi and Aqara but is prolearned from the American Honeywell, which suggests and guarantees a high quality level on this specific type of device.

The front The device has a perforated grid (well made, also on the aesthetic level) which hides the smoke detection device which, infiltrating the grid, they are detected by the electronic components. If the sensor is connected to a gateway Xiaomi or Aqara, against a smoke detection (adjustable in sensitivity) it is possible to receive a notification (via app mobile), to make sounds to the gateway and more. By default i gateway Xiaomi / Aqara emit a very high-pitched sound for about a minute. The sensor itself proit produces an extremely sharp alarm sound.

The dimensions, as mentioned, they are limited, as well as weight, around 30 grams. The device is powered by a standard CR123 button battery (see pictures below); the battery level is communicated to the control unit via proProtocol ZigBee, protocol also used for reporting any flooding detections and for the pairing initial.

Il pairing - or the installation - takes place by combined use of the gateway and of the sensor itself: taking for granted the previous, initial configuration of the gateway on 'app, it will be sufficient to open theapplation (taking care to be on it Wi-Fi of Gateway) and hold down the back of the sensor that hides a button: after three seconds the sensor will be detected by theapp e will be added to the operating environment at which it can then be configured in terms of notifications and automatisms.

The construction materials struck us for quality and compactness. Use is obviously limited at the range of radio transmission between sensor and Gateway that in the field ZigBee, the air line is certified for at least 100 meters (without obstacles and in the absence of signal repeaters).

Talk about the grade compatibility of a single component ZigBee it makes little sense. In fact, these components cannot be used alone but only coupled with an element BRIDGE/Gateway ZigBee↔︎TCP/IP, therefore its compatibility derives directly from the degree of compatibility of this "collector" element to which it is associated.

We have a way to test cars with success this associated sensor:

Use of the sensor associated with gateway Xiaomi and Aqara provides partial compatibility with Google Assistant e Amazon Alexa, while the service is not supported IFTTT. As we will see below, these limits can be circumvented in some cases by the degree of integrability of these gateway. Furthermore, while the gateway Aqara it is natively compatible with Appthe HomeKits, gateway Xiaomi is not.

Use with ConBee and RaspBee implicitly provides a high degree of compatibility, given that these two gateway work directly with personal HUBsoftware.

Owners of Homey can directly use the sensor without needing gateway (it is Homey itself), therefore since Homey is compatible with Google Assistant e Amazon Alexa (as well as IFTTT), it also becomes the sensor.

Domotics integrability

The degree of home automation integrability, as for compatibility, it goes through the gateway to which the sensor is connected.

Il gateway Xiaomi it can be integrated with practically all realities HUB best known software:

  • Home Assistant (see integration guide);
  • Homebridge (to render the gateway and therefore the accessories connected to it compatible Appthe HomeKits);
  • Domoticz;
  • openHAB.

As compatible natively with Appthe HomeKits, il gateway Aqara it cannot be integrated with HUB personal software. In practice using a gateway Aqara it is not possible to integrate the accessories connected to it profirst personal home automation. The alternative to solve this proproblem exists: use the sensor with the gateway of the line Xiaomi, which can be integrated with personal HUB(unlike the Aqara). A clarification is a must: given that the HUB perosnali are in turn compatible Appthe HomeKits, the fact that the gateway Xiaomi is not compatible with Apple HomeKit is a not-proBlema.

If instead to integrate the sensor to the proprio personale HUB do not want to use a gateway Xiaomi / Aqara can be used alternatively elements like the BRIDGE/Gateway software deCONZ combined with antennas ConBee and / or RaspBee (the first with any computer the second specifically with Raspberry Pi). Another alternative: it is possible to integrate the sensor through the BIRDGE /Gateway given by the binomial zigbee2mqtt + CC2531.

Homey, as mentioned, contains an antenna in itself ZigBee, therefore it is able to autonomously integrate the sensor without the need for other components.

Detailed evaluation:

Constructive quality
Use: quality and experience
Honeywell Sensorand of Fumo - BoAThe Xiaomi smoke detection sensor we really like because it costs very little and allows us to monitor with simplicity (and effectiveness) the presence of any fumes, consequently of possible fires. The great domotics integrability not only allows us to receive notifications (not only from theapp the possible gateway, but from our personal home automation based on HUB personal), ma also and above all to insert the sensor which trigger for eventual - saving - automations, for example remote notification of the state of emergency.

A smoke sensor can save a house (and its occupants).
Highly recommended.
