Two way switch without wiring

Last day I had site which is not automated but they want to make one switch to two way. The wiring of the two way switch was not good.

So we take two fibaro relay and one controller. And connect these relay to the controller and just join two relay (if one relay is turned on then other will also on). And connected to both the switches And removed the controller from the house.

Now the switch is working like two way switch without using the controller
