Comparison · Updated 2026-03-28
Verdict
For any property > 6 rooms, IoT reading pays for itself within the first year just on labour + error savings. Beyond that, it unlocks prepaid, live analytics and remote control — none of which manual reading can match.
Manual meter reading quietly burns operational hours and introduces transcription errors that feed tenant disputes. IoT automation eliminates both.
