Does anyone recognise this energy monitoring chip? The marking I see is
"1852AVH":

The "8" is really a "B". Try 1B52AVH instead.

Unfortunatly, I couldn't find anything with that part number using
Google search.

It's in an Aldi (Medion brand) WiFi smart plug.

Model number? Photo? Any patent numbers in the docs?

I couldn't find the logo:

I don't know if this is the same product, but it's easy enough to try:
"Kankun Runs on OpenWrt firmware"
