The external antenna gives it connectivity far superior to other relays with just an internal antenna, which makes this relay a great choice for difficult locations. I am using one of these in a metal shed inside a grounded, metallic electrical box (antenna poking out of the box) and found no issues whatsoever. Review: Finally, my ceiling fan is smart - This relay is well designed and constructed. It can power larger fans, many similar products do not. While on the large side it includes two independent controllable outputs which is perfect for a fan with attached light. The included, antenna allows the relay to be hidden within a metal fan housing. The package also includes a plastic bracket which I found very useful. I did find the bracket' which is supposed to hold the relay with plastic tabs friction mount, to need a little work. It seems to work well if attached to a wall but I was forced to mount it upside down in the fan housing. Space limitations meant the relay was very close to the revolving fan blade mounting bracket. The vibrations caused the relay to partially slip out of the bracket, falling to within a few mm of the revolving fan mount. I solved this with duct tape and the installation is now secure. My only quibble is with the antenna with a self sticking pad on the end. Again with revolving fan blades, it is very important the antenna is secure. I cleaned the painted steel fan housing with alcohol. Let the surface dry and pressed the adhesive pad for a full minute. It seemed to be secure. But, after several hours of the fan running, the adhesive failed and the antenna almost became entangled with the fan blades. Fortunately, I caught it in time. I reinstalled the antenna with black duct tape which is not very noticeable in my case as the housing is black. I coupled Aqara Dual Relay Module T2 with the "Aqara Smart Light Switch (with Neutral, Double Rocker). I now can control the fan's on/off and the light individually. I can preset timed operation and contol both fan and light through the Aqara Ap or through Alexa. ## Features - [Compatibility Features] The Dual Relay Module T2 is compatible with a variety of mainstream ecosystems, like Matter (A Matter compatible Aqara hub is required), Apple HomeKit, Alexa, IFTTT, and the Aqara Home app. This broad compatibility allows for easy integration into diverse smart home setups and usage in smart home automation - [Dry Contact Mode] The Aqara Dual Relay Module T2 supports dry (or potential-free) contact mode with both pulse and on-off switching, allowing for the integration of a wide variety of electrical devices such as boilers, garage doors, and more into your smart home setup - [Wireless Switch Mode & Motor Control Interlock] The T2 provides easy and secure control of tubular motors and can also function as a roller shade switch (percentage control not supported; supports basic up/stop/down control). Utilizing the Wireless Switch Mode, the T2 can convert an existing wall switch into a scene controller without requiring any wiring changes. For example, a button can be assigned to arm your wired doorbell or security system, enabling the integration of other wired sensors into your smart automations (AC only) - [Energy Saving & Power-off Memory] With advanced energy monitoring, the T2 helps maintain optimal control over energy consumption (Note: The energy monitoring feature is only available in wet contact mode). Leveraging the Zigbee protocol, the T2 features significantly 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 - [Safety and Installation Flexibility] The T2 supports overheat protection, overload protection, and a customizable power limit that automatically shuts off the device if consumption exceeds specified settings, directly safeguarding your home and energy footprint. Additionally, it can be installed near a light, behind a switch* or wall outlet, and includes a DIN rail mount.

Relative to most compact in box switches this one is near 2x the size of others I've used before. On the other hand only 1 of those were dual relay but still 1/2 the size easily fitting behind most switch or outlet types. For USA exterior usage to control 1 duplex outlet (each receptacle on a relay) I had to install a dual gang pvc surface mount box with wet service in use cover box just to fit this giant in 1 gang space. It's too tall wide & deep to fit along side or behind any outlet...might fit very snug to a simple single dtsp switch πŸ€·β€β™‚οΈ. If you were to install it in a deep plastic single gang new or existing construction box you may be able to get it to fit, but I'd recommend using stranded thhn wire over solid romex for the terminations between device and fixture. It looks and feels substantial so they get kudos there. In the US we really don't use din rails all that much but I certainly have had cases where it could come in handy for other purposes. Functionally I like it. Being it's zigbee saves some wifi bandwidth in a residence with 200 plus ip devices. The switch or sensor connections give it additional flexibility for usage. The power tracking, scenes & automation abiliies work as expected. Also appreciate substantial lugs which can accept 12 gauge wiring and sufficiently torque it down without fear of stripping the threads. It would be nice if set up (schematics) were included in the print manual since the aqara documentation for it on their website is near impossible to locate. Still feel it's a skoche overpriced for what it is. But it definitely tries to make up for that by doing it's job well while being we constructed. If they could miniaturize this more perhaps by going w SSR or triacs over mechanical relays it would be a real winner. ## Frequently Bought Together - Aqara Dual Relay Module T2,Matter Over Bridge,Requires Aqara Zigbee 3.0 HUB, Dry Contact Mode for Garage Doors and Boilers, Light Switch & Roller Shade Switch, Supports Homekit and Alexa - Aqara Smart Hub M3 for Home Automation, Matter Controller, Thread Border Router, Features Zigbee, Bluetooth, Wi-Fi, PoE, IR, Supports Alexa, Apple HomeKit, SmartThings, IFTTT - Aqara Zigbee Door and Window Sensor 3 Pack, Wireless Mini Contact Sensor, Home Automation, Requires Aqara Hub, Zigbee Connection, Kid Safety, Compatible with Apple HomeKit, Alexa, Works with IFTTT --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.sa/products/636056139-dual-relay-module-t2-smart-relay-switch-dry-contact-mode](https://www.desertcart.com.sa/products/636056139-dual-relay-module-t2-smart-relay-switch-dry-contact-mode) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-06-21*
