Steps
Register a developer account and application at developer.home-connect.com to get a client ID, then have the customer complete OAuth 2.0 authorization at https://api.home-connect.com/security/oauth/authorize to grant read access to their Bosch/Siemens/Neff appliance
Exchange the returned code at https://api.home-connect.com/security/oauth/token for an access token, valid 24 hours
Call GET /api/homeappliances to list the customer's connected appliances and get each one's haId
Call GET /api/homeappliances/{haId}/status/BSH.Common.Status.OperationState to read the current operation state (Ready, Run, Finished, Error) before dispatch
If the state reports an error condition, check for an associated event/fault code to relay to the technician ahead of the visit
Known gotchas
Full production access to real (non-simulated) appliances requires Home Connect to approve the registered application beyond the sandbox/simulator tier
Access tokens expire after 24 hours, so a monitoring job needs a working refresh-token flow, not just a one-time token
