    Good morning i need help please
    my project is to control solenoid valve that I used it with raspberry the program is done by python language , i want to control this solenoid valve by a switch that is in dashbord of a remote server so to connect this server and raspberry card I used the mqtt my problem is when I click on the switch for the opening and closing of the solenoid valve I receive nothing
    the second problem that I used the relay to convert from 5 v to 24 v to order the solenoid valve but I do not know if it is a good solution or not, and in this case of conversion can i use the UPS system or not ..

    How about a circuit diagram? Our crystal balls are collectively blind at the moment.
    A schematic diagram would enlighten us.
