I am trying to monitor my HP printer and found the custom integration at GitHub - elad-bar/ha-hpprinter: HP Printer Integration. I did once manage to install it ok but since then I have had to rebuild everything and I think there has been a new version of HA.
When I follow the same instructions and add it to the custom_components folder, I know it has been found by HA since the log has the line:
We found a custom integration hpprinter which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant
However when I try to add it as an Integration, it isn’t in the list. What have I done wrong or not done?
