## Description

From the manufacturer

Review: Otimo custo beneficio - Otimo custo beneficio
Review: Works great for motorized blinds... - One of the few dual switch in the market that can be connected to existing curtain manual switches such as Norisys and at the same time to wifi for automation with Alexa providing full Alexa functionality. The motor auto calibrates and then Alexa Voice command can have blinds Open in percentage terms eg 30%, 70% etc. After returning 2 other brand switches finally got this feature running on Sonoff! Super cool. Blinds can now be automated to open on sunrise, close partially at sunset and completely close at given time. Dismissing Alexa alarm in morning can be automated to have the blinds open 50% for gentle sunlight waking up. Works great!
