Thanks for all your writing on these topics Simon! It has turned me from a bit of a naysayer to an optimist around this tooling, especially being able running stuff locally with access to tools. Have an M4 Pro mac mini arriving this week to have a similar self hosted setup over tailscale.
Maybe related, but I've also got a tailscale instance running for the same use case (on an older it box but...) I've also installed open-webui attached to ollama. That way the interface I can deal with when on my phone is just a simple nice to use webpage. May want to look into this? Thus far it's worked very slick.
