This prevents the integration from crashing when the PVS is offline or during network issues. The fix logs a warning and skips virtual device creation when PVS is missing, allowing the integration to continue operating with available devices. Normal operation resumes when PVS data becomes available again. Fixes issue where integration would error out after working for a while with 'KeyError: PVS' in the logs. --- custom_components/sunpower/__init__.py | 10 ++++++++++ 1 file changed, 10 insertions(+)

Key improvements: 1. Guaranteed PVS device presence - PVS device is now always added to device list, even if sysinfo fetch fails - Uses sensible defaults (host-based serial, 'PVS' model) as fallback - Prevents 'PVS device not found' crashes in downstream code 2. Enhanced error handling in _vars() method - Added explicit 400 Bad Request detection with debug logging - Logs response body for troubleshooting LocalAPI parameter issues - Added HTTPError handling before generic RequestException - Provides clear error messages about endpoint support 3. Graceful degradation for device fetches - Meters: Logs warning if fetch fails, continues with empty dict - Inverters: Logs error + debug traceback if fetch fails, continues - Integration continues operating with whatever data is available - No crashes when individual device types are unavailable 4. Improved logging - Moved logging/traceback imports to top of file (cleaner code) - Changed missing inverters from ERROR to WARNING (normal for some configs) - Added informative messages explaining inverters may be aggregated - Added summary logging showing counts of devices fetched - Changed traceback from ERROR to DEBUG level 5. Code quality improvements - Removed inline imports, moved to top-level - Consistent error handling patterns throughout - Clear comments explaining behavior - Maintains full backwards compatibility These changes make the integration resilient to: - Temporary PVS connection issues - Incomplete LocalAPI implementations - Network timeouts and intermittent failures - Systems where inverters aren't exposed via LocalAPI Tested with PVS firmware build 61845 returning 1 PVS, 2 meters, 17 inverters. --- custom_components/sunpower/__init__.py | 5 +- custom_components/sunpower/sunpower.py | 77 +++++++++++++++++--------- 2 files changed, 54 insertions(+), 28 deletions(-) diff --git a/custom_components/sunpower/__init__.py b/custom_components/sunpower/__init__.py index 1bd2cc7..4b82f3e 100644 --- a/custom_components/sunpower/__init__.py +++ b/custom_components/sunpower/__init__.py @@ -127,8 +127,9 @@ def convert_sunpower_data(sunpower_data): _LOGGER.error(f"Device {i+1}: TYPE='{dev.get('DEVICE_TYPE')}', SERIAL={dev.get('SERIAL')}, MODEL={dev.get('MODEL')}") if INVERTER_DEVICE_TYPE not in data: - _LOGGER.error(f"CRITICAL: Inverter device type '{INVERTER_DEVICE_TYPE}' not found!") - _LOGGER.error(f"Available device types: {device_types}") + _LOGGER.warning(f"No inverter devices found - this is normal for some PVS configurations") + _LOGGER.info(f"Available device types: {device_types}") + _LOGGER.info("Inverter data may be aggregated in meter readings or unavailable via LocalAPI") create_vmeter(data) diff --git a/custom_components/sunpower/sunpower.py b/custom_components/sunpower/sunpower.py index c03f0df..9081903 100644 --- a/custom_components/sunpower/sunpower.py +++ b/custom_components/sunpower/sunpower.py @@ -1,5 +1,8 @@ """SunPower PVS client with automatic LocalAPI/Legacy CGI fallback.""" +import logging +import traceback + import requests import simplejson from urllib.parse import urlencode @@ -234,6 +237,17 @@ def _vars(self, *, names=None, match=None, cache=None, fmt_obj=True, retry_count else: raise ConnectionException("Authentication failed after retries") + # Handle 400 Bad Request - might indicate LocalAPI not fully supported + if resp.status_code == 400: + # Log the response body for debugging + try: + error_body = resp.text + logger = logging.getLogger(__name__) + logger.debug(f"400 Bad Request response body: {error_body}") + except Exception: + pass + raise ConnectionException(f"Bad Request (400) - LocalAPI endpoint may not support these parameters.
