I purchased this EU Power Monitoring Plug on ALIEXPRESS in July 2024. It has the reference JR-PM09.

It is equipped with the LN882H module and it did not seem compatible with alternative firmware. After searching online, I found this topic:
[LN882H] [WL2S] Elivco 20A BSD34 EU Power Monitoring Plug [BL0937]
https://www.elektroda.com/rtvforum/topic4032240.html
I followed the procedure below using the software "ln_download_tool_V3.0.1" and the firmware "OpenLN882H_1.17.662.bin" to reprogram the chip.

The reprogramming worked well.
I used the pinout of the ELVICO plug.
My plug is recognized in Home Assistant
Hoping that this topic can help other JR-PM09 owners.
Here are photos of the plug:
