Blind Control with lctech x2 relay
Posted: Tue Jun 01, 2021 7:48 amHi everyone!!
I have the project to control my roller blinds using a lctech 2 way 5v relay, but I have some trouble by using it. The relays are acting weirdly. Some time they switch on, some time they don't, some time with a delay, some time they switch off before they have to... It is very random...
I am pretty sure of my code because it is working like a charm if I don't use the lctech x2 relay but by connecting directly other relay to the ESP.
Best regards
ps: sorry if it isn't clear, my english is far from perfect
