Tensorflow tff in practice

I am currently trying to set up a centralized server for federated learning with TensorFlow. I have read the tutorials but I can not find a way to connect to remote clients. After reading the most asked questions I found out that tff is not yet able to be used in productions with mobile phones. Is this also the case for computers and servers? Is there a way to use tff with actual clients instead of simulation data? Or is the current version still only meant for the testing of new algorithms?
Thanks in advance.
