Abstract

This study presents a differentiated reanalysis of telemetry from a stand-alone solar-powered smart irrigation prototype. Instead of repeating the final-project summary, the analysis uses an updated August export containing 602 additional observations and applies continuity, completeness, temporal harmonization, ceiling-aware soil-moisture, and rule-consistency audits. The combined dataset contained 12,025 unique timestamps from 1 July to 9 August 2026. No missing value was interpolated. Sampling gaps greater than 30 minutes formed 42 sessions, while ten core telemetry fields were simultaneously valid in 63.29% of records. The two soil-moisture channels produced 3,819 paired observations and 3,682 paired five-minute bins. The automatic and manual channels reached the 100% ceiling in 71.25% and 46.35% of paired records, respectively; daily median differences were therefore zero percentage points with an interquartile range of 0-6. Across 3,789 valid battery-voltage and Energy Management System code pairs, threshold agreement was 99.60%. After 9 July, panel and battery voltage ranks were strongly associated (rho=0.995), with a median offset of 0.06 V. The extended audit confirms reliable rule classification and closely tracking voltage channels, but it also shows that sensor ceilings, incomplete environmental readings, and absent pump-ON history prevent valid claims about irrigation, water, or energy efficiency.
