Question 7 months ago

Hello! I ran your program for a personal project. I want to modernize the old intercom. Instead of the button I put a relay which is actuated by the intercom ring signal. It works perfectly, it sends me a message in IFTTT, but the relay remains activated as long as the ring signal exists (as if the button is kept locked). As long as the button is locked, the message is forwarded to IFTTT continuously. Can you help me with a code so that if the button remains locked (example for 30 seconds), the IFTTT message will be transmitted only once? Thank you very much !
