Sonoff S-Mate 3-channel remote control transmitter compatible with Mini R3

The Sonoff S-Mate transmitter works with the Sonoff Mini R3. The S-Mate is a radio transmitter module that is paired with the Sonoff Mini R3. A standard light switch is connected to the S-Mate module; one S-Mate module supports a maximum of three buttons/switches. The Sonoff Mini R3 is a simple Wi-Fi-controlled relay that requires L and N lines to operate, but it has one important feature: a radio receiver that allows it to work with the S-Mate module. In this configuration, the Sonoff Mini R3 acts as a gateway, relaying signals from the S-Mate to the cloud, which can then be used to create scenes. The switch's signals are not only used to control the Sonoff Mini R3, with which the S-Mate has been paired; they can be used in any way. Connection: Connecting the L wire between the S-Mate and the Mini R3 is optional. The S-Mate is battery-powered. S-Mate module specifications: Power supply: 3V CR2032 battery Application: eWelink Communication: radio Range: 50m Operating temperature: -10°C ~ 40°C Permissible room humidity: 5% - 95% RH Material: PC V0 Number of connectable wall switches: 3 Dimensions: 51 x 45 x 24mm Cable dimensions: Φ 1.5mm~3.0mm Certificates: CE/FCC/RoHS Color: White No neutral cable required Can be used in a staircase system Works with 1/2/3 key switches Compatible with Amazon Echo and Google Nest. In combination with Sonoff mini R3, it allows you to connect, for example, lighting in old-type installations (where there is no Neutral cable) Adding S-Mate to the eWeLink app For the S-mate to be visible in the eWeLink app, you must assign it to Sonoff Mini R3. To do this, find the Sonoff Mini R3 in the eWeLink app, click on its options, and in the "eWeLink Subdevices" tab, add the S-Mate remote control. After adding the S-Mate to eWeLink, you need to create scenes that will control relays, etc.; simply adding the S-Mate to the Mini R3 will not control the relay. The set includes: Sonoff S-Mate x1. Sonoff Mini R3 is not included. Visit our blog for more interesting solutions and articles. We also invite you to like our Facebook page to stay up to date with electronics. elty electronics and you
