About

Enhanced SunPower monitors SunPower PVS5 and PVS6 solar systems from Home Assistant over the local network. It needs no cloud service and talks directly to the PVS, which is set up in the UI by entering its IP address and the last five characters of its serial number. It adds sensors, binary sensors, numbers, selects and switches, including individual inverter health tracking and SunVault battery monitoring. Battery control modes and the reserve percentage can be changed from select entities on the PVS device. Optional WebSocket live data brings real-time power updates, with a power change threshold and a write interval to limit database growth. Alerts can go to a mobile device or by email, covering a PVS going offline, inverter failures, low flash memory and flash wear. The integration requires newer PVS firmware.

Setting it up

Install it from the Marketplace and restart Home Assistant, then add it under Settings, Devices and services.

Enhanced SunPower - Connection Setup

PVS IP AddressPVS IP address
Polling Interval (seconds)How often to poll PVS (10-3600 seconds, 20s minimum for battery). Note: PVS updates gateway sensors every poll, but meter/inverter data updates every ~5min regardless.

Enhanced SunPower - Authentication

PVS Password (last 5 chars of serial)Last 5 characters of PVS serial number (e.g., if serial is ABC123XYZ78901, enter 78901)

Enhanced SunPower - Notifications & Advanced

Show status notificationsPolling success, system status, 'integration is working' feedback
Show debug diagnosticsCoordinator cycles, timing details, data conversion (WARNING: generates many notifications with fast polling)
Replace status notificationsPrevents notification accumulation by reusing the same notification
Mobile device for critical alerts
Email notification serviceSelect email notification service from your Home Assistant notify services (select service to enable emails)
Email recipientRecipient email address (required when email service selected)
Flash memory alert thresholdAlert when PVS flash memory drops below this amount - % for new firmware, MB for old (set to 0 to disable)
Flash wear alert thresholdAlert when PVS flash wear exceeds this percentage - shows EMMC lifetime consumed (set to 0 to disable)

Enhanced SunPower - Advanced Settings

After setup

PVS Serial (last 5 characters)Last 5 characters of PVS serial number (found on device label)
Enable WebSocket live dataSubscribe to PVS WebSocket for real-time sensor updates
Power change thresholdMinimum kW change required to trigger a state write for power sensors. Reduces database writes at the cost of some precision.
Sensor write intervalHow often power sensor values are written to HA (1-60 seconds). 1s gives maximum resolution. Higher values reduce recorder database growth.
