Water Heat Pump integration (Energie 270L)

Hi all,

My Water Heat Pump has a wifi adapter that I would like to (also) integrate in HA to get daily measures of water consumption, water temperature, etc. Unfortunately already contacted the company and they don’t provide any public API. Below is the wifi adapter that seems to use a ESP8266 or similar. Would it be possible to create a gig to read data from it?

hello. anyone?
