Hi,
I am new working with the ha and have same problem with the energydashboard and my ESP32 Watermeter.
I am working an the AI on the edge watermeter-projekt. I tried to integrate the ESP32-cam to my ha.
I want to show the usage of water on my energy-dashboard but cannot add the sensor I tried to create in the yaml-File. I can add the WatermeterValue but not the usage in l. Also the calculation for the usage of water doesn’t seem to work:
Here’s my config file:
mqtt:

I am looking forward to some feedback from you.
Best regards
