    Hi. I need your help on the subject of controlling a 12v linear actuator. I have a 4 channel Smart 12v module, which I am currently using to start the pump at a given time - here it is so simple that the relay short circuits the contact and the function is simply on/off. With an actuator, I need to open it at a given time and close it at another, so there must be a polarity change. Please tell me how to do this in the simplest way. I don't want to overcomplicate things. Please find attached pictures of the components. Thank you in advance. 12V linear actuator with wires.

    Well you understand, it should work.
    I still want to make sure with one question - I connect the receiver (actuator) to the COM contacts of these relays ?

    I also recommend the ESP8266 plus relay module and the trivial ESP EASY programming language. https://botland.com.pl/moduly-wifi-esp8266/82...ul-wifi-esp8266-nodemcu-v3-5904422300630.html
