Scalar–tensor theories are constrained with lunar laser ranging and supernova data at low redshift. This allows us to find some constraints on the scalar field independently of the form of its potential once the gravitation function is specified. We apply these results to some well-known scalar–tensor theories, showing that they agree with the ΛCDM model at 1σ.
