SONOFF S-MATE2 Extreme Switch Mate – Battery-Powered eWeLink-Remote Sub-Device, 1/2/3-Channel Switch Control, No Neutral Required
Overview:
• The SONOFF S-MATE2 Extreme Switch Mate is a compact battery-powered switch mate module designed to turn traditional wall switches into smart remote controllers.
• It can connect with ordinary 1 / 2 / 3-button wall switches, allowing the existing switch to trigger smart control actions without directly carrying the lighting load.
• The device works as an eWeLink-Remote sub-device, and it requires a compatible eWeLink-Remote gateway device such as MINIR4, DUALR3 / DUALR3 Lite, M5, or NSPanel Pro to perform local control scenes.
• The S-MATE2 is powered by a CR2477 battery, so it does not require a neutral wire in the switch box, making it suitable for retrofit smart home installations.
• Compared with the previous S-MATE version, S-MATE2 is more compact, offers longer battery life, and supports single-click, double-click, and long-press actions when connected to a push-button switch.
