RF Modulator and AV Sender

[Sir Osis]

Hello.
I've got an RF modulator and cheap video sender for my H2S.
The picture comes in fine on the 2nd tv but I can't change channel.
The video sender came with a IR sensor but no matter where I put the sensor near the front of the H2S I cannot get a reaction from the remote from the 2nd tv.
Any ideas?

They IR sensor wont work Just use a app like Vu+ on your phone

Is there any way to change channel besides the phone app Tich?
