The SONOFF MINIR3 is a compact in-wall Wi-Fi switch that enables remote and voice control of connected lighting, fans, or other appliances. It connects to the eWeLink app over an IEEE 802.11 b/g/n 2.4 GHz network and integrates with Google Assistant, Amazon Alexa, Samsung SmartThings, and Yandex Alice for voice control.

With a maximum load of 16 A and an input/output voltage of 100–240 V AC 50/60 Hz, the MINIR3 handles a wide range of household loads. Its PC V0 enclosure with IP20 protection and TUV, CE, FCC, and RoHS certifications confirm it meets safety and electromagnetic compatibility standards.
