Cisco Meraki repurpose?

I have some Cisco Meraki equipment that I have sitting at work doing nothing. We purchased it, test it out for a year and didn’t really like it that much. so we never re-upped the license.

is there anything i can do with the equipment, like flashing it and install pfsense on it?

or is it pretty much just a pile of junk now?

I have never tried it, but some models support this
