I’ve built a small Niagara N4 bundle with preconfigured trend extensions (5-minute interval, 14-day retention) and a couple BQL queries that flag hunting SAT loops and simultaneous heat/cool on AHUs; this trimmed my call-backs by about 30% on a 420-VAV site in June. If you want the files or have suggestions for better KPIs, like a simpler way to normalize mixed-air temperature to OAT, say the word and I’ll post the package.
