    Does any one here have experience with the Clipsal powertags?

    Do they measure bidirectional power flows? I have a PV system that regularly exports power and need a solution that can see the difference between export and import modes.

    First thing to note is there are various different models of powertags under different brands.

    Last time I looked the Clipsal branded ones were part of a "Wiser Energy" product, which was a residential cloud based system with an app but no integration. This was some time ago now so it may well have changed.

    The SE branded ones however have an ethernet gateway with Modbus TCP that does integrate quite easily with the NAC.

    These will do bidirectional *power* measurement (ie you can see the current power as being positive or negative), but they only accumulate energy (ie measure kWh) in one direction...

    If you want to accumulate both import and export kWh then I suppose you could always put two on the same circuit in different directions.
