I have been using HACS to install custom components since it has come out and even before that I used to do it manually. Now I have noticed that even when custom components are installed in HACS successfully, it doesn’t appear in the integrations tab of my Home Assistant running as docker in Rpi4. I have also tried to install some with the old way, copying files directly into custom_components folder. Here again I am not able to pickup any new installations in the integration tab. I am running the latest version HA 0.118.5 and supervisor 2020.12.6
Found the issue. It was some error with the supervisor. Just had to restart it
