Home automation smart hub, 433MHz with zigbee?

Hi everyone,

I have 2 different smart hubs controlling my home, both uses RF 433MHz
1 in the ground floor – broadlink RM Pro from http://www.ibroadlink.com/
1 in the 1st floor – SAVVY controller from https://www.savvythings.net/

Now, i want to add zigbee devices on each floor. is there a smart hub that operates both RF 433MHz and zigbee?
