I want to measure how much the AC outside unit is eating, which is connected to a direct 230V (EU) cable (just an outside box, no socket).
I have a spare Aqara T1 switch which I think would do the job but I am afraid it is not certified for 24/7 on 16A circuit.
Shelly 1PM or Shelly EM look great, but I don’t want to add a single Wi-Fi device to my existing smart home until I exhaust options.
Use the Pro version of those, that will give you a RJ-45 ethernet connection(FE).
That is what I’m using for the furnace and outside unit
Shelly Pro EM-50 (coils on each leg)
Shelly Pro 1PM (setup using detached switch mode and monitoring the current for fan when heating/cooling/air circulation) so far seeing only 0.5 to 10 amp draw depending on speed of the DC fan
Also using the Shelly Integration

Shelly EM Mini Gen4 has zigbee.
But it’s “out of stock” at the moment.

Thanks for the suggestion, but I don’t have option to bring ethernet to the balcony where the AC unit will sit.
It is wireless too. 2.4 GHz WiFi, but gives you power monitoring.
