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 ..
