1 relay with two separate on and off gpio

ritual · 2022-04-25T20:48:59+02:00

I have a water tank installed at my place which has two sensors in, one is at the bottom (LS) and one is at the top (US). Whenever the water level goes below LS the relay to the motor turns on and as soon as the water hits the US that same relay turns off. Until yesterday i was using US as a button in supla which turns off the relay locally and used US as action trigger to turn on the relay. But yesterday i don't know if it was a local problem or there was a server problem i was not able to access the app,nor was i able to see any devices on supla,as i used LS as action trigger to turn on relay i was unable to turn on the relay manually and fill my water tank. What i was wondering is ,if there is any way there can be a local version for the two gpio buttons for the same relay for which one button only turns on the relay and other only turns of the relay regardless of high/low state. Thank you.

great.
In this way it is much safer in case of water tanks with additional manual control.
