Does this look like something that can be used? Honestly I dont even know if it is the right protocol. But it is not DSMR

Looks like corrupted data. If you have a standard ESP32 (not S2), you need to connect the input to GPIO16 and use uart2. GPIO18 will utilize software serial which is not capable of 115k bauf.

@toast1234 Are you aware that you need a pullup resistor on the P1 port data line, as it is a Common collector output? 3k to 3,3V or 4k7 to 5V will work.

I have heard of one case where activating the internal pullup on the GPIO was sufficent, but I consider that "pure luck", as it is in the order or 25-30k.

[toast1234]

It is actually one of these https://smartgateways.nl/product/slimme-meter-wifi-gateway/ After reading more I came a cross this page https://www.bjerke-energi.se/wp-content/uploads/2021/09/Aidon-RJ12.pdf so maybe it is just that its binary.
"HAN interface can enable DLMS-COSEM based binary protocol according to standard 62056-7- 5 or ASCII-based protocol mode D according to 62056-21."

[gskjold]

This software supports both. Your debug output suggests there is data corruption.

[toast1234]

ok, thanks! I will look in to it more later

Working after re-routed GPIO18 to GPIO16 and inverted signal (115200, 8N1, inverted)

Right - you need pullup AND inversion (either in hardware or in code).
