    Sonoff 4ch smart switch
    Very good smart switch from sonoff. I bought it to control the sprinkler system and the lights in my yard. I have the sprinkler valves connect to a dc 24v and the lights on 220v and it works with both currents. It works perfect true the app and u can make tone of different scenarios for the 4 channels. The remote is also very nice and for older people who find it difficult to use phone apps. Build quality seams very good for the money and i recommend the switch to every one.

    You need to open the switch and change working mode by toggling internal toggles. ( default setting is “switching on one of the channel switching off all the others” and its normal. I tried 12volt/0.5A generic adapter to power the switch for testing and it works as expected. After setup, it takes 3 second to become ready, after any power outage...amazing.
