Setting up home assistant sandbox

I want to set up a development sandbox for my home assistant instance, but i need to work with live data from my production instance.

Is there a way for me to set up a second home assistant , and then have it copy selected live data from my production instance via the api?

For instanse, i need it to only fetch live solar production data, but i cant configure both to read from the source integration.

You can use this component to link another instance GitHub - custom-components/remote_homeassistant: Links multiple home-assistant instances together
