My goal is to have the relay turn on while the sensor is HIGH/ detecting motion but only if the button on the webpage is set to "on" (When R1 == "on")
It connects to wifi, displays the webpage and has no problems with any of the buttons or anything. The one problem is that when R1 == "on" the PIR sensor isnt activating the relay.
Im pretty sure the code for the relay should be something along the lines of
S1 is the PIR state
R1 is the relay
R1State is the state of the relay
It connects to wifi, displays the webpage and has no problems with any of the buttons or anything. The one problem is that when R1 == "on" the PIR sensor isnt activating the relay.
