Hi
I think you guys should create a way to send ir comands with blynk so I could control tv and stuff like that
I do that already:) Controlling projector and AC with Arduino and IR LED.
Very simple project which you can build in an hour.
If you combine the IR Library to receive, decode and send IR codes with the Blynk Library, you can do this.
I used these 2 tutorials to learn the IR part. Currently working on the Arduino UNO:
Cheers
I’m searching a lot but cant find a way to control the AC with blynk, do you have a tutorial or something like this to share?
You should search better 
There are tons of tutorials on how to use IR with Arduino:

Start without Blynk:
Use Arduino IR library to record signals from your remote, then play it back. Make sure it works
Then add Blynk on top of it.
There is even a post on the forum:
