*Somfy / 1241755*

> The Sonesse 28 WireFree Zigbee (Li-ion) is a 12 V battery motor for roller shades and blinds. It runs on a built-in lithium-ion battery that Somfy rates for one recharge a year, reports shade position and battery level in the TaHoma app, and takes voice control through the TaHoma switch. It suits Home Assistant users, with native support through Zigbee. HomeKit, Google Home and Alexa users reach it through an integration (the maker's hub).
