After quite searched the net how I could get out for less, this remote Jolly Open seemed to be the best product level programming simplicity and above level price.
In practice this unit records the unique signal in 433 MHz of the original remote control, to reproduce identically. Make sure your original system does not use "Rollingcode" a process which permanently change the transmitter signal.
Less than a minute for the program, I'll test it and there: it works !!
A very good product for a price that really stands out from other similar products.
