Ask HN: Brother printers sending ink data to Amazon?
If you have the printer on your network, and any Amazon device on your network, the Amazon device could easily query the printer for ink levels. My Home Assistant does this and I never connected HA to the printer. It’s just part of the status information the printer seems to make available on the network.It’s not surprising to me that Amazon would do this using one of their devices, as everyone seems to be grabbing as much data as they can. It’s probably described in the T&Cs somewhere (that they can scan your network and use data from it).
