Looking for a good library helm chart

Hi,

I run a 3 node Kubernetes cluster for some stuff at home (smokeping, Home assistant, LibreNMS, etc.)
However not for all things there is a chart, and for some things I built my own Docker container or even Helm chart.

But that leaves me to maintain my own helm chart which I don't feel like doing.
Does anyone have a good base helm chart which I coud use?

I tried looking at the Bitnami one but the documentation is unclear and I still have to do a LOT myself.
Truecharts is an option, but their focus is on their NAS product, not Kubernetes.
What do you use? Any suggestions which I could use?

Thanks!
