Not sure what brand so no command. Too many brand in the market now days. Now with all this third party wifi module in the market almost everything u can control online already so nothing special anymore only see the module is compatible to most plat form like alexia, google home, zigbee and etc. If only support their then not so user friendly like DC Moto Iot.

If u like to look for brand that hv own factory in Klg valley then can consider Dnor.
