What is the purpose of the green dot that shows up when you manually turn on one of the relays?
Once it has been turned on and back off why does the green dot stay on when turning off the relay via the button and then only goes off when touching the green dot?
The green dot that shows up indicates that the relay has been overridden from its default state. Normally, the relays are in "auto" mode meaning they are controlled by the logic in the code (ie, your loop() ). When you use the app to force a port ON or OFF, you are overriding their default logic/mode. Thus you are turning the port ON and it will stay ON until you return it back to the AUTO mode (or if you turn it OFF for good). So the green dot is a way to clear out the override mask and return the port to it's automatic mode that is controlled by the logic.
The iPhone app has a blue dot. (I made it green to match the green android logo.
)
When you turn off a relay that is already on via the programming and then turn it back on using the android app does the relay go back to its programmed state? If I want to turn on a relay for say a few days (my ro) and have it ignore the programmed state how is this done without first turning the relay off and then back on? or can you even do this?
To do this, you would manually turn it on by choosing ON from the app (to force it ON). Then when you are ready to return it back to it's normal state you would click on the green dot to return to normal. Otherwise it would stay in the overridden state forever (or until you restart the controller).
The idea behind the override is that you are specifically wanting a port turned ON or OFF and you know what you are doing. This came from the lights ON and OFF modes in the menu and also with the feeding and water change modes. The modes had to have a way to override the logic to force a port off (or on) and keep it that way while running so as to prevent unwanted events from happening during the different modes. (You wouldn't want your powerheads to cycle ON while you were in the middle of feeding OR you wouldn't want your return pump to turn back ON when you had 25% of your water out of the tank for a water change.)
Hopefully that clarifies things for you.
