[Proximity]For a sturdy connection, ensure that the Aqara Dual Relay Module T2 is within 400 inches of the Aqara Zigbee hub, and the hub is within the same range from the Wi-Fi router. Additionally, make sure the hub and the router are on the same local area network (LAN). *Note: Requires a secured 2.4 gigahertz Wi-Fi network connection for Hub M2/ M1S/ E1/M1S Gen2 and Camera Hub G2H Pro, and 2.4/ 5 GHz Wi-Fi for Camera Hub G3.(Wired connection via Ethernet RJ45 for Hub M2 is also supported).[Dry Contact Mode] The Aqara Dual Relay Module T2 supports dry (or potential-free) contact mode with both pulse and on-off switching, which allows you to integrate a great variety of electrical devices such as boilers, garage doors and much more into your smart home setup. (*Note: Neutral wire is required.)[Wireless Switch Mode & Interlock for Motor Control] The T2 offers easy and secure control of tubular motors, and can also function as a roller shade switch. Additionally, with the Wireless Switch Mode, the T2 can turn an existing wall switch into a scene controller without requiring any wiring changes. For example, a button can be designated for arming your wired doorbell or security system. This feature also allows integration of other wired sensors into your smart automations (AC only).[Energy Saving & Power off Memory] Integrating advanced energy monitoring, the T2 can ensure you maintain optimal control over your energy consumption. (Note: The energy monitoring feature is only available in wet contact mode). Thanks to the Zigbee protocol, the T2 features ultra lower idle power consumption compared to Wi-Fi relays, leading to reduced energy costs. Additionally, equipped with a power-off memory function, the T2 retains its last state even after power interruptions.[Electrical Safety & Flexible Installation] The T2 supports overheat protection, overload protection and a customizable power limit that automatically shuts off the device if consumption exceeds your specified settings, directly safeguarding your home and your energy footprint. Also, the T2 can be installed near a light, behind a switch* or wall outlet and even includes a DIN rail mount.
