looking for bi-directional 3-phase meter

Hello, I'm looking for bi-directional 3-phase meter in EU. Were getting solar panels soon, and I'd like to measure the sold electricity as well.

My system is HASS, zigbee2mqtt, NodeRed, InfluxDB, and Grafana running on Raspberry 4.

It should be preferably installed din rail (got lots of space) and zigbee. Z-Wave is fine too, and if nothing else is found, wifi. Modbus etc sounds too complicated.

Any good leads? The bi-directionality seems to be a tough nut. Most of the time it's not mentioned, and the ones I've found are modbus.

For example Qubino meter does not mention this. And Carlo Gavazzi EM340 while having bi-directional measurement, only has pulses and modbus.

Also checked Brultech but the documentation was a bit lacking, they did lot even list the size of the box anywhere. Also no prices. Would need to get the "industrial" one for 3-phase.

So far Shelly 3EM seems to be the best and cheapest option. Really would not like to use WiFi if possible, but it's an option. In that case I probably would build my own wifi network just for automation - maybe even exclude it from the internet.
