Product description: Shelly Uni - universal WiFi module
Shelly Uni's universal WiFi module, which allows you to control any legacy device viaWiFi, such as a coffee machine. Powered by 12 V to 36 V DC and 12 V to 24 V AC. The module is equipped with2 digital inputsthat support voltages from 2.2 V to 35 V DC and from 12 V to 24 V AC, as well astwo potential-free outputsthat allow switching voltages up to 36 V AC and up to 24 V DC / 100 mA. ThreeDS18B20temperature sensors can also be connected to the module. The board is protected by a plastic cover that protects it from moisture, dust and accidental short circuit.
