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

I have an Emporia 16-way - you need plenty of space in your consumer unit - a 1-phase standard UK one would probably struggle but we have 3-phase so bigger and easier to fit. I don’t use it for PV but I think you can. Main use is to be able to monitor individual circuits consumption. The “API” such as it is, is tricky I think
