GE Appliances, a division of appliance giant Haier, provides licensed technicians with a SmartHQ Service. SmartHQ allows repair workers to “communicate directly with appliances for real-time diagnostics.” The service also provides service manuals for devices. Signing up for the service gives you a mobile app, how-to videos, tech support, and a handheld Bluetooth module that connects to appliances. Signing up without GE Appliances Authorized Servicer status costs $919, if you pay ahead for a full year. $720 of that fee is access to the mobile and web versions of SmartHQ.
