Frequently asked questions
How does authentication work?
The server uses OAuth 2.0 with a client ID and secret. You must configure authorization and token endpoints for account linking in the Actions on Google Console.
What data does the server access?
It accesses smart plug data (ID, name, on/off state, online status) via the Smart Home API. No local device data is stored.
Does the server support real-time updates?
It provides automatic device state refresh, but the README does not specify push-based real-time updates.
How are errors handled?
Errors include specific codes for configuration (`CONFIG_ERROR`), API errors (`API_ERROR`), device not found (`DEVICE_NOT_FOUND`), and command failures (`COMMAND_ERROR`), each with a message and details.
