Xiaomi air purifier shows not up in integrations


I’ve tried to install the xiaomi air purifier integration from https://github.com/syssi/xiaomi_airpurifier via HACS.
It installs, I restart HA, but it is not selectable via integrations. There is no error or something else in the logs. The files are in the custom components folder, so everything looks fine. Does anybody else have a similar issue?
