Should I just throw my Aqara contact sensors (MCCGQ11LM) away?

Is this the hub?

Yes.

@danabw

And is the control cloud-based or is this local control?

By default cloud. However, it supports HomeKit and @SmartHomePrimer described recently how to use Home Assistant to bring these into Hubitat locally in this post:

HomeKit device sync w/ Hubitat Elevation (No Apple devices or Node-Red required)

[UPDATE] There's a far better way to do this now that isn't limited to binary devices and lets you do all the automation in Hubitat where it's easy and powerful. I've been chasing this one for a while. I'm not a fan of working too hard at making home automation work for me. This is one of the primary reasons why I'm here and no longer a SmartThings user, among several other disadvantages of that platform. I'm addicted to home automation, so it should come of no surprise that I'm willing to try…

I don't have this hub - I have two of the Mijia hubs, and I didn't need internet access to either pair the devices or use them. I would bet the Aqara hub is similar, but @SmartHomePrimer would know for sure.

@danabw

I had read in another thread that the Ikea Tradifi (sp?) repeaters can support these types of devices.

Been there. Done that. They are more stable with compatible repeaters, but no where near as stable as on an Aqara/Mijia hub.

Edit: BTW, that Aqara hub is much cheaper on AliExpress
