How to make orvibo touch classic wall switch in configuration mode?


Does anyone know how to pair on HomeMate App with orvibo touch classic wifi wall switch via the ZigBee mini hub connected to my wifi.

I had it removed from my homemate app with two switches but when I followed the instructions ie. press four times and fifth time Long pressed till it flickers fast, then click once more and a steady slow blinking light will be shown. I tried this multiple times but it still doesn’t connect but at “Adding device” mode then eventually failed as it complain the switch not in configuration mode in which I already did do. I tried to reduce my devices but still no luck.

Anyone can please kindly advise if you guys encounter this before.

Thanks in advance.
