On the module and in the enclosed manual, you can find the label for DC power supply of the device in the interval 30-50V DC. This is due to UL certification, which sets the safe limit at 20% (upper and lower) of the declared power supply. This means that the module can operate in the 24-60V DC range and is safe to use at such voltage levels.
The device only works on 2.4 GHz WiFi b/g/n.
The device does not work only on 5 GHz WiFi ac.
The device supports REST API control and MQTT protocol.
Control a wide range of home appliances and office equipment (lights, power lines, garage doors, curtains, security systems, heating radiators, air conditioners, etc.) from anywhere with the smallest WiFi-operated double relay switch with roller shutter functionality in the world – Shelly 2.5
