Hello,
I’am very new to HA. The goal is to make a HA dashboard to use on a tablet. This tablet will go one a wall and will function as a central info en settings hub.
One of the things I would like to show is the current power output of my solarpanels. I have a wifi KWH meter on the solar converter. On the dashboard I have a sensor card showing the data from that KWH meter. BUT it shows negative values. I want this to show positive values. How can I do this?
Thanks in advance for any help.
