cargoBuildFlags?

Is there API of that function described somewhere for quick reference? Besides the little tutorial section...

Actually, using just cargoBuildFlags (--bin thermostat as release is already included) causes the build to fail, as the default builder forces --target=x86_64-linux.

One usually has to RTFS of nixpkgs for this kind of extended documentation :)
If there's no easy solution then overriding buildPhase is fine.

Did you test this? I think this doesn't work and you need python3.withPackages instead.

This is the lab computer and those packages are already included in the system Python. You can use nix develop --ignore-environment to isolate the system profile (see https://github.com/NixOS/nix/issues/4359).
