So basically i'm doing a project where i connect the lights and fans of my house to arduino and connect a esp8266 module to it and control the lights and fans using blynk app.
But the other thing i wanted to do is using a bluetooth module and build a bluetooth remote using another arduino and a keypad so that whenever i press a button the keypad the signal is ssent via bluetooth to the arduino which controls the house lights.So i wanted to know if this is possible can i control the lights using both the blynk app and a blurtooth remote or is there a limitation.
And another thing is how to if the bluetooth way works whenever i press a button to turn on or off a light how to update the state in the app also?
So if the light is shown on in the blynk app and i press a butoon on my bluetooth controller to turn off the light the light state in the app should also change ow do i do that. I’m a complete beginner/noob and i do not under stand how virtual pins and blynk write virtual pin works if thats important.
