Aqara vs Shelly Smart Home Specs
Connectivity options
Aqara uses a single protocol for its sensors, relying on Zigbee for communication with its dedicated hub. This requires a specific Aqara Hub, sold separately, to function. In contrast, Shelly offers a multi-protocol approach with Wi-Fi, Zigbee, Matter, and Bluetooth support. The Shelly 1PM Gen4 does not require a separate hub, allowing for direct connection to your home network. This flexibility lets you integrate devices without buying extra hardware. You can choose the connection method that best fits your existing infrastructure. Shelly provides more immediate setup options, while Aqara demands a specific hub ecosystem for operation.
Smart home compatibility
Both brands support major voice assistants, but the scope differs. Aqara sensors work with Apple HomeKit and Alexa when paired with an Aqara Hub. This integration allows for local alarms and basic automations. Shelly expands this list to include Google Home, Home Assistant, and Samsung SmartThings. This broader compatibility gives you more choices for your central control system. You are not locked into a single platform. Shelly also supports Matter, ensuring future-proofing for new devices. Aqara focuses on deep integration with HomeKit, which is ideal for Apple users. However, Shelly covers a wider range of popular platforms for diverse smart home setups.
Energy monitoring
Aqara sensors focus on detecting physical states like door openings. They do not measure power usage or provide energy data. Their role is limited to triggering alerts or automations based on contact status. Shelly 1PM Gen4 includes built-in power metering capabilities. You can track real-time energy consumption for appliances like water heaters or washing machines. This feature helps identify energy-hungry devices and optimize usage. You gain visibility into how much power each device uses. Aqara offers no such data. If you want to monitor electricity usage, Shelly provides this specific functionality. Aqara simply reports open or closed states without any power metrics.
Physical dimensions
Size matters for installation in tight spaces. Aqara sensors are compact, with the main unit measuring 1.61 by 0.87 by 0.43 inches. The magnet is even smaller at 0.79 by 0.39 by 0.39 inches. These small dimensions allow for discreet placement on doors or windows. Shelly 1PM Gen4 is larger, measuring 1.65 by 1.46 by 0.63 inches. While still compact, it is bulkier than the Aqara sensor. Shelly fits behind wall switches, which may limit placement options in some boxes. Aqara wins on sheer smallness for contact sensors. Shelly is designed for electrical boxes rather than surface mounting. Your choice depends on where you plan to install the device.
Setup requirements
Aqara devices require a dedicated hub to function. You must purchase the Aqara Hub separately to enable notifications, automations, or HomeKit integration. Without the hub, the sensor cannot connect to Alexa or IFTTT. This adds complexity and cost to your setup. Shelly devices are hub-free. You can set up the Shelly 1PM Gen4 in under ten minutes using Wi-Fi. It connects directly to your network, simplifying the initial configuration. You do not need to buy additional hardware to get started. Shelly also acts as a Bluetooth gateway, further reducing the need for extra devices. Aqara’s reliance on a specific hub makes the setup more rigid compared to Shelly’s direct connection.
