New measuring hardware

As it looks like my current data collection (through efergy engage hub) and energyhive is getting unreliable, I am looking for an alternative that preferable can play nicely with HomeSeer zwave home automation system in Australia.

I would need to measure 3 phases and single solar output ideally bypassing any third party.

Does anyone have any suggestions?
Any experience with Emporia?
What about managing it all through HomeSeer?

Any thoughts would be greatly appreciated
