hey there.
i got some issues with code… everything working, except i dont getting any data from dht sensor (temperature and humidity). so thats relay working on ESP12f and for getting data from dht sensor. relays working fine and DHT seems working, at least led light and it getting warm (means working).
I working both with web and android version - its just showing some same numbers for temp and humidity all time. here what i got set in blynk.console and code, thank you:
also, maybe you could tell me, how i can get text from serial as separate datastream?
