Bug Fix: PVS5 Setup Failure
Release Date: March 23 2026
Type: Bug fix
What's Fixed
PVS5 systems could not be added to Home Assistant
PVS5 firmware does not include a standalone BUILD field in its supervisor/info response. Instead, the build number is embedded in the SWVER string (for example "2025.11, Build 5412"). The integration was looking only for a standalone BUILD field, found nothing, and fell back to legacy mode. Legacy mode returned a 403 error because PVS5 new firmware requires authentication. Setup failed entirely with no clear error message.
Three issues were corrected:
-
The integration now falls back to parsing the
SWVERfield when no standaloneBUILDfield is present. The build number parser already handled this format; it just was not being called with SWVER as input. -
PVS5 is now correctly identified as new firmware (varserver) regardless of build number. The 61840 build threshold applies only to PVS6 hardware. Any PVS5 with a detected build is treated as new firmware and uses the varserver authentication path.
-
The 60-second polling minimum intended for old PVS6 firmware no longer applies to PVS5. PVS5 with new firmware follows the standard 10-second minimum.
Who Is Affected
PVS5 hardware owners who have not been able to add the integration. PVS6 users are not affected.
Upgrade Notes
- Standard HACS update or manual file copy, restart Home Assistant
- No configuration changes required
- PVS5 users who previously could not set up the integration should now be able to add it normally
