Representative

Aqara

₹1,990

A Rs1,990 device whose entire value is measured against the cost of the thing it prevents.

Buy it if: Anyone retrofitting an older Indian switchboard that has no neutral wire at the switch.

Avoid it if: Anyone without a Zigbee hub -- this cannot be used standalone, unlike a Wi-Fi module.

Buy it if: Anyone with a geyser, water tank, or washing machine on a floor that would be expensive to water-damage.

Avoid it if: Anyone without a Zigbee hub -- there is no standalone siren on the sensor itself.
