Hi Tsar,
Yes, I was able to manage. I use ESPHome, so ESPHome has a P1 integration. You only have to use an ESP module and connect the output (transmit line) of the Smart Meter to an input of the ESP. The ESP is even powered by the Digital Meter.
The ESP with ESPHome delivers all entities. No need to install a HA integration like P1 Monitor or DSMR Slimme Meter.
These are the most important entries in my ESPHome configuration:

rx_pin: 3
baud_rate: 115200
The rx_pin off course depends of your hardware setup

The Smart Meter sends every second or 2 seconds information. In my opinion overkill so I added the filters: throttle option to limit the data.
Works as a charm…
