I don't know what kind of html fritzing produces. But you can normally copy html tables into excel/openoffice and export a csv/xls from there.

@Japio I think I've seen the esp start some wifi stuff in parallel to the arduino startup code. Could be that if the gateway setup is delayed the wifi will not start as expected. You could use a timer, initialized from before() to cycle the leds during startup. Just wondering, do you call some form of yield() during the led setup?

I tried to reproduce, did not happen again. I am not using a mobile device, just Firefox in windows 10. But as I said now it works. Quite frustrating when you can't see what you're typing..... Thanks for your response.

@pihome I have a sketch at https://github.com/mfalkvidd/Arduino-Datormagazin-Pomodoro/blob/datormagazin/Arduino-Datormagazin-Pomodoro.ino but I think it is easier to just follow the instructions in the wifimanager readme.

There are many examples... https://forum.mysensors.org/topic/3764/p1-smart-meter-nta8130-readout-using-mysensors/7 Or on GitHub, needs some tinkering to integrate in mysensors https://github.com/search?l=C%2B%2B&q=P1+meter&type=Repositories Edit There is also a library available https://github.com/matthijskooijman/arduino-dsmr
