sorry my bad English is not my native language, and the code is long. I’m using a node CMU and an ACS 712 20 A sensor, in order to be able to trigger a lamp either by the Blynk application (<3) or by the physical button , and call the app and shut down the fisico.porem I am not able to make it work … “both” the codes were tested separately and worked. but when “together” does not work, trying to update the status of the virtual button and led in the app. if the serial monitor opens, strange letters appear or nothing appears.
