Hello . Thanks for the reply when i received it i send you pics of the pcb . Do you think it was possible that the sonoff basic or this product sonof 4ch work with an input of 24vac and then an outpout 24vac . I want to use one one them to pilot and program a solenoid valve for the garden . It was difficult to find that on the web.
