The Shelly 2.5 is a dual WLAN switch and thus allows the connection of 2 consumers or is suitable for controlling a roller blind. The maximum load is either 2x2300W or 2x10A. For both channels the power consumption is measured individually. The device is also protected against overvoltage and overheating. The module can be flashed with an alternative firmware (Tasmota) via the interfaces located on the back.
