Kogan SmarterHome Zigbee Temperature and Humidity Sensor

The Kogan SmarterHome Zigbee Temperature and Humidity Sensor (model KASMSRTHZ1A) is a compact, battery-powered climate monitor designed for indoor use. Measuring approximately 47 by 40 by 23 mm and weighing 25 grams, the device monitors indoor conditions without requiring mains wiring. According to product specifications, it records temperatures between -20°C and 60°C (with an accuracy rating of ±2°C) and relative humidity between 0% and 100% (accuracy of ±5% RH). Because it relies on the Zigbee 3.0 protocol, it does not connect directly to home routers; instead, it transmits readings to a compatible Kogan SmarterHome Zigbee gateway, which bridges the data onto your home network.

Who it suits

This sensor suits renters and homeowners already invested in the Kogan SmarterHome ecosystem who want automated tracking for specific indoor rooms, storage cupboards, or plant zones. Because the unit includes adhesive backing and does not require hardwiring, it works well for rental properties where drilling holes into walls is restricted by tenancy agreements. Check your state tenancy regulations regarding wall adhesive fixings before mounting to prevent surface damage.

Conversely, anyone looking for a standalone unit or an at-a-glance readout should look elsewhere. The sensor features an LED status indicator for pairing but omits an LCD or e-ink screen, meaning you cannot read current conditions without opening the Kogan SmarterHome application. Furthermore, smart-home enthusiasts looking to tie climate data into broader setups like Apple Home, Home Assistant, Google Home, Amazon Alexa, or Matter-based controllers will find no confirmed native integration on this model.

Australian notes

According to Kogan Australia, the sensor is sold locally through retailers including Kogan and Dick Smith with a one-year Australian manufacturer warranty. The sensor itself is entirely battery-powered, eliminating the need for mains electrical work or local Australian plug adapters. Manufacturer details list power as either a CR2032 coin cell or a CR2 battery, with a stated lifespan of up to two years under normal operation.

To transmit data to the Kogan SmarterHome app on iOS or Android, the device must pair with a separate Kogan SmarterHome Zigbee gateway. That gateway requires a standard 2.4 GHz Wi-Fi connection, meaning dual-band Australian home routers must have their 2.4 GHz band enabled during setup. Additionally, the sensor is rated solely for indoor environments and carries no official water-ingress or weather-resistance rating for outdoor Australian conditions.
