There is one thing this device will do - capture the MACs/IPs/DNS from the phones and trucks/vans that are bringing ballots in after the cutoff. That alone might not seem big, but add that info to other data showing election fraud and you will then have real people and vehicles to point to as accomplices. They could be arrested, questioned, and used to get to the real criminals.

Theoretically if these devices capture the same MACs at different precincts (especially in different counties or states) it would be damning evidence - especially if there is also video evidence.
