Best way to test CPEs TR069 implementation with GenieACS

Hi everyone,
the doubt/question we have is quite general so we are writing here to get some suggestion about how to solve it.
We must perform some tests on the CPEs we are thinking to send to our customers. So we just need to test some specific parameters getting their values or writing them.

For the majority of our needs we can set/get the values doing the query from the GenieACS web pages but sometimes could be helpful for us to get them from a cli interface.
As example what could be the best (or racomended) way to perform a GetParameterValues from the Device. level ?
If we do that using the GeniACS web ui we never see a query message send out from the ACS with this specific query but the ACS do a get of subtrees then assemble them.

Which could be the best way to do that?

Many thanks!!
