You must have a crystal ball
The IRIO with TWS module is under development, and it is being designed to fit into a DIN rail housing
The current sensing will also have an analog reading so you can see the current level and you can set different sesitivity so it can cater for low current led lights or high current lamps
If this is in design now, can you consider making the switching arrangement suitable for mid point 3 way switching.
What I mean is, if you have a two pole change over relay and expose all of these, it can be used at the mid point to switch between the straps (pair of switched lives).
In our house all lights and switches are home runs back to din rail cabinets. We gave some lights that are two ways switched using 3+e cable. With the above I would be able to switch these too at the cabinets.
There is no need to duplicate the current sensing on both poles, although it would be nice.
