Selection of a Sonoff module to control water cooling in the dispenser

The discussion focuses on replacing the rocker switch in a water dispenser that controls the cooling function with a smart Sonoff module to automate activation based on external temperature. The switch in question is responsible for enabling the compressor when water temperature rises. It is clarified that the power supply to the dispenser is independent and the switch simply closes the cooling circuit. The recommended solution involves using a relay circuit connected in parallel to the existing switch to simulate its closing action. A voltage-free (dry contact) Sonoff module is suggested to safely close the circuit without introducing voltage, but it must be capable of handling the current present in the circuit. A specific Sonoff Basic R2 model designed for voltage-free switching applications, compatible with HomeKit and Supla, is proposed as suitable for this purpose.
