🌐 Web query:

plugwise python-plugwise-usb 0.47.8 discover_coordinator discover_network_coordinator source

💡 Result:

The terms discover_coordinator and discover_network_coordinator are not found in the python-plugwise-usb library [1][2][3]. Searches indicate that these specific function names do not exist within the plugwise_usb package codebase [1][2][3]. The python-plugwise-usb library is designed as the USB backend for Plugwise devices [1][4]. The library requires a stable Plugwise Zigbee network, where a Stick must be linked to a Circle+ node [5][6]. During initialization, the library typically performs automatic discovery of linked nodes within the Circle+ memory [5][7][6]. If you encountered these terms, they may be confused with unrelated libraries, such as rlx-driver (a Rust crate), which contains a function named discover_coordinator [8][9][10], or other messaging/protocol libraries like kafka_protocol [11][12]. For interacting with Plugwise USB devices, you should refer to the official repository at https://github.com/plugwise/python-plugwise-usb [1]. If you are looking to integrate these devices with Home Assistant, the maintainers provide a beta custom component (plugwise_usb-beta) [1][4][13]. The library functionality is generally invoked by connecting to the USB stick, which then triggers a scan of the network [7]. Manual configuration or linking of devices is often recommended to be performed using the original Plugwise Source software, as the python library's manual methods are not documented [5].

Handle a missing coordinator before forwarding platforms.

With plugwise-usb==0.47.8, StickNetwork.discover_network_coordinator() returns False when the Plus-device does not answer. Stick.discover_coordinator() discards this result and returns None, so setup continues to forward platforms without a coordinator. Check the discovery state and raise ConfigEntryNotReady when discovery fails.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In `@custom_components/plugwise_usb/__init__.py` at line 103, Update the setup
flow around Stick.discover_coordinator() to detect a failed or missing
coordinator result, including the None/False outcome, and raise
ConfigEntryNotReady before forwarding platforms. Preserve normal platform
forwarding when coordinator discovery succeeds.
