### 5/5 — Does exactly as promised

*2025-08-26, version 1.19.0*

I’ve been using Lumi for 3 months now and it has delivered exactly as promised! It accurately measures your power consumption with single digit variance. I was able to cut down by bill from 15k to 10k just by reacting to Lumi’s live data on my consumption. 

The app is clean, informative and concise, so digesting the info and making appropriate energy saving changes is easy! It’s perfect for anyone looking for data-driven changes.

Can’t wait for when they make this available for business use.

### 5/5 — Great App
