SONOFF MINIR4 Smart Two-Way 1-Channel Switch Wi-Fi

Smart 1-channel switch for electrical appliances, supporting remote control via Wi-Fi 2.4GHz; designed for various home appliances. The improved R4 version of the Sonoff MINI switch, with an extremely small size, is called Mini Extreme. The SONOFF smart home system allows you to control electrical appliances remotely using the 'EWeLink' app or by voice with 'Amazon Alexa' or 'Google Home'. It allows you to create various scenarios, group devices to turn on/off multiple devices in your home with one touch, set desired timers and schedules, monitor the status of your home and devices in real time, and share their control. By linking the 'EWeLink' app with the digital automation platform IFTTT, you can further expand the possibilities of scenarios. The devices of the Sonoff smart home system have the built-in ability to operate in a local LAN network without a cloud server. Features: The smart switch is easy to install and control remotely from a smart device using the eWeLink mobile app (Android, iOS). The relay signal is transmitted via a 2.4GHz Wi-Fi network. LAN mode is supported. The R4 version has improved build quality and includes an ESP32 chip with BT support. The MINI R4 version switch is also called Sonoff Mini Extreme because it supports external switch control. It can be easily connected to a momentary switch, door exit switch, SPDT switch, lock switch or even dry contact sensors. By connecting a pair of two-way switches, you can turn on/off the light at the bottom of the stairs from the top of the stairs and vice versa. When paired with the Sonoff S-MATE switch, MINIR4 can be controlled locally via the 'eWeLink-Remote' signal up to 50m away and activate other smart scenario devices. Sonoff S-MATE is purchased separately. A new feature of the MINI R4 is the 'detach relay' mode, meaning that the states of the external switches and the relay can be separated, then using the external switch button will not affect the relay. When this mode is activated, the smart device will operate according to the setting or smart control and will not respond to the mechanical button. The external switch can still be used in smart scenarios to activate another device or groups of devices. Like other 'eWeLink' relay modules, it supports on/off, power on/off/memory (last state), smart scenes (automation), and auto on/off functions. Allows you to set a delay for devices to turn on after a power outage to protect the network from overload. Small and compact switch, 40% smaller than MINIR2 and even 60% smaller than MINIR3. Thanks to its extremely small size (only 33 x 40 mm), it fits even into the smallest EU type/86 type/120 type distribution boxes. Made of PC fire-resistant plastic, V0 class. This switch is compatible with a variety of other products (e.g. motion sensors, door and window sensors, etc.) to complement smart home scenarios.
