Error message

ex

What it means

UpdateFailed raised in AsusWrtBridge.async_get_data when the asusrouter library raises any AsusRouterError while fetching raw data (the new asusrouter-based API path). The library error is chained; 'ex' in the log is the exception repr. This is the generic failure signal for every sensor datatype fetched through this bridge method.

Solutions

1. Re-run the integration's reconfigure flow to refresh credentials/API access
2. Update the asusrouter python package and the HA integration
3. Verify the router's remote/HTTP API is enabled and the model is supported by asusrouter
4. Check the chained exception in logs (UpdateFailed __cause__) for the library's specific message

try:
    data = await bridge.async_get_data(datatype)
except UpdateFailed as err:
    cause = err.__cause__  # original AsusRouterError
    _LOGGER.warning("asusrouter fetch failed: %r", cause)
    raise

When it happens

Trigger: self._api.async_get_data(datatype, force=force) failing: HTTP API errors on newer ASUS routers, authentication errors, connection resets, unsupported datatype for the router model.

Common situations: Router HTTP API token expired or revoked; router model lacking a sensor (e.g. no temperature sensors); asusrouter library incompatible with the router's firmware API version.
