The Avatto ZWSM16-1-Zigbee is a compact smart switch module designed to bring intelligent control to your existing home lighting. Operating on Zigbee 3.0, this single-gang device integrates with Tuya Smart and Smart Life apps, allowing you to manage your electronics via Amazon Alexa, Google Assistant, or Yandex Alice. It supports a wide voltage range from AC 100-240V to DC 24-32V and requires a neutral wire for stable operation. Encased in a white fireproof acrylic housing, the module measures 39 x 39 x 19 mm, which ensures it fits comfortably inside most standard wall switch boxes. It is rated for an IP20 protection grade and can maintain a connection range of up to 100 meters. You can customize how your lights behave using the timer, schedule, and countdown functions, while the power-off memory feature lets you choose whether the device stays off, turns on, or restores its previous state after a power failure. This module is a practical choice for those who want to modernize their home without replacing their favorite physical switches, as it supports rocker, state-sync, and self-reset modes. Whether you are automating a bedside lamp or a ceiling fixture, the 16A maximum load capacity for LEDs provides flexibility for various lighting setups.
