on GitHub

What's Changed

• Update to version 4.8.3 with proxy TEDAPI optimizations by @jasonacox in #665

v4.8.3 - Docker Compose Updates

• Update pypowerwall to v0.13.2 - See updates: https://github.com/jasonacox/pypowerwall/releases/tag/v0.13.2 with improved connection health monitoring and graceful degradation. Including:

v0.13.2 - TEDAPI Lock Optimization

• Fix TEDAPI lock contention issues causing "Timeout for locked object" errors under concurrent load by optimizing cache-before-lock pattern in core functions
• Optimize get_config(), get_status(), get_device_controller(), get_firmware_version(), get_components(), and get_battery_block() to check cache before acquiring expensive locks
• Remove redundant API call in pypowerwall_tedapi.py get_api_system_status() method
• Fix proxy server KeyError when status response missing version or git_hash keys by using defensive key access
• Fix proxy server KeyError when auth dictionary missing AuthCookie or UserRecord keys in cookie mode
• Improve performance and reduce lock timeout errors in multi-threaded environments like the pypowerwall proxy server
• Enhance compute_LL_voltage() function with voltage threshold detection (100V) to better handle single-phase systems with residual voltages on inactive legs, as well as split- and three-phase systems.
• These optimizations benefit all methods that depend on the core TEDAPI functions, including vitals(), get_blocks(), and get_battery_blocks()

Proxy t77 (11 Jul 2025)

• TEDAPI Lock Optimization and Error Handling: Enhanced proxy stability and performance with comprehensive fixes for TEDAPI-related issues.

  • Fixed KeyError exceptions in proxy server when status response missing version or git_hash keys by implementing defensive key access with .get() method
  • Fixed KeyError exceptions when auth dictionary missing AuthCookie or UserRecord keys in cookie mode, now uses safe fallbacks
  • TEDAPI Performance Improvements: Optimized core TEDAPI functions (get_config, get_status, get_device_controller, get_firmware_version, get_components, get_battery_block) with cache-before-lock pattern to reduce lock contention
  • Removed redundant API calls in TEDAPI wrapper functions to improve response times
  • Enhanced multi-threading support for concurrent proxy requests with reduced lock timeout errors
  • Improved error resilience for different connection modes (local vs TEDAPI) that return varying data structures

• Enhanced Health Monitoring: Added comprehensive endpoint statistics tracking for better observability and debugging.

  • Endpoint Call Statistics: Added tracking of successful and failed API calls per endpoint with success rate calculations
  • Enhanced /health endpoint: Now includes detailed statistics showing:
    • Total calls, successful calls, and failed calls per endpoint
    • Success rate percentage for each endpoint
    • Time since last success and last failure for each endpoint
    • Overall proxy response counters (total_gets, total_posts, total_errors, total_timeouts)
  • Improved /health/reset endpoint: Now also clears endpoint statistics along with health counters and cache
  • Automatic tracking: All endpoints using safe_endpoint_call() automatically tracked (includes /aggregates, /soe, /vitals, /strings, etc.)

Proxy t78 (14 Jul 2025)

• Power flow animation update: Show an image of a Powerwall 3 instead of a Powerwall 2 if it is a PW3 by @JEMcats in jasonacox/pypowerwall#193
