@goddur I'm sorry my friend. I think this question is not related to MySensors. I've googled it for you. https://www.instructables.com/id/ESP8266-to-IFTTT-Using-Arduino-IDE/

@goddur Hi, and welcome to the forum! So what exactly is your question/problem? If it is the time until you get a stable reading after reset of the Arduino, you could just count the time until you get a stable reading. Then include this delay after startup before reporting the first value and you're done. Something like: static int startupCycles = 10; // 10 seconds initial startup delay void loop() { delay(1000); Irms = emon1.calcIrms(1480); // Calculate Irms only if (startupCycles) { --startupCycles; return; } if (Irms < .2) { // your original code... } }

In the default wiring, D1 is the only unused pin that is easy to work with. D2 is used for CE so using it to blink a led as well will not work.

@gohan Indeed... See e.g. my experience here: https://forum.mysensors.org/topic/2890/chinese-rubbish-or-is-it
