I’d imagine by wires that just aren’t visible. Even auto flushing toilets need power for the sensors, not that unusual.
Comment on Can somebody explain to me why this needs Bluetooth?

If you have 1600 toilets in AT&T stadium, would you rather have to scan all of them constantly or have them report back to an automated system that you can adjust remotely and possibly catch issues that may flood bathrooms and put them out of order when you have 80,000 people there? Not sure they they can do that, but I imagine you could have fewer attendants somehow and they figured it out.

bt doesn’t have huge range and afaik the max number of active devices bt can use simultaneously is 7.

The stadium has WiFi as well, and 5ghz not 2.4ghz signals could reach all of the building, they would all have to be networked back into devices/ software designed for it. So according to your numbers you would need to mesh 250bt receivers into a network running to their specialized software
