With the new Shutter Switch H2 EU, Aqara (link) has launched a control solution for bidirectional AC motors. Such drives are found in European tubular motors for roller shutters and similar applications. They have four connecting wires, two of which are responsible for controlling the direction of rotation (“up” and “down” or “forward” and “backward”), while numbers three and four serve as neutral and protective conductors. By switching the voltage to the respective control wire of the drive, the motor runs in the desired direction.
Choice of Zigbee or Matter over Thread
Like other models in the Aqara H2 EU series, the flush-mounted switch supports either Zigbee or the Thread radio protocol. The latter allows it to be integrated directly into Matter platforms such as Apple Home, Alexa, Google Home, Home Assistant, Homey, or SmartThings. In this case, no Aqara hub, such as the M3, is required for installation – only a Thread Border Router needs to be present in the respective ecosystem.
In addition to the rocker switch for up and down (left half), there are two additional buttons on the front. These can be used for control tasks in the smart home, such as calling up scenes or starting automations. Depending on the connected system, multiple assignments are also possible – with a short, long, or double press of the button.
Compatible with 55 mm Switch Frames
The 55 mm form factor installation option and electrical design (100-250 V, 8 A) comply with common standards in Europe. The switch can also be combined with other products in the series, such as the H2 EU light switch, the H2 EU dimmer switch, and the H2 EU wall socket, using the multi-frame available as an accessory.
Automatic end position detection (“Smart Calibration”) sets the end positions in Thread/Matter mode without any further action for the user. In Zigbee mode with an Aqara hub, these positions can be fine-tuned via the app – for instance, leaving a gap for plants on the windowsill. Even then, integration into Matter systems remains possible, since the hub functions as a Matter Bridge and passes its Zigbee devices through to the platforms.
