No balance when create an address object from seed

[charlesaugdupont]

When I create an address as follows:

import zbsby as pw
address = pw.Address(seed=s)

where s is my seed phrase, I am able to recover the correct address object (public and private keys are as I expect them to be). However, the balance just says zero. How do I actually check my balance for a particular network? I have the node address as well as the matcher address.
