NEVERMIND, dumb question. Mqqt client only recieves topic when one publishes it.
Basically want I want to know is if I create an mqqt topic, how long after creating the topic (and not updating it) will mqqt clients be able to access the information.
I have some timers set up on a due that doesn't have eeprom for saving variables after reset and I'm trying to avoid Fran..... I have the due connected to an esp8266 mqqt client that publishes and reads different topics.
My thought was to save the timer info to the cloud when someone changes the timer information, then the only time I would read the topic was when I lost power... But that could be like months apart....
