If you’re still having problems, I used @dwradcliffe’s fork as a starting point and had Claude Code refactor this entire integration and add enhancements by analyzing node-intellicenter and a decompiled version of the Pentair Android application.
Supports websockets (port 6680) and raw TCP (port 6681) as well as zeroconf discovery. Communications should be a lot more stable with built-in retry and incremental backoff. I also had it implement a queueing and deduplication mechanism as well as optimistic updates so the integration feels a lot more responsive in general.
