Do you have a Linky smart meter? This compact yellow device is a powerful tool for cutting energy costs.
Setting aside debates about its connectivity, I'll focus on practical strategies I've tested to lower electricity bills. Installing the Linky doesn't save money on its own—it's the real-time insights it provides that make the difference.
As someone who's deeply analyzed Linky data and optimized my own home setup, I can guide you on using it effectively.
Discover my expert tips for maximizing savings with your Linky meter:


The Linky meter lets you monitor consumption in real time, regardless of your supplier—whether EDF, ENGIE, or Ilek.
This visibility is key to savings. Linky shows hourly usage and graphs pinpointing peak consumption periods.
Analyze these to identify high-usage devices and adjust habits accordingly.
For instance, nighttime usage should be minimal. My Linky revealed excessive draw from standby devices: two computers, three screens, Freebox, PS4, and Switch—like a mini NASA control room.
By powering them off completely, I saved €46 annually.
ADEME estimates households can save up to 10% using these features, accessible via your Enedis personal account or the "Enedis by my side" app.
Previously, precise tracking required extra hardware. Savings: €46

With clear consumption data, optimize your meter's power subscription. Higher kVA means higher costs—adjust to avoid overpaying.
Supplier guidelines:
- 3 kVA: <50m², 1 major appliance, no electric heating.
- 6 kVA: <80m², 2 major appliances, electric heating.
- 9 kVA: >80m², 3 major appliances, electric heating.
- 12 kVA: >100m², 3+ major appliances, electric heating.
Gas-heated home? I downsized from 6 kVA to 3 kVA, saving €32.75 yearly on subscription.
Request changes via your supplier—never DIY. Linky enables remote adjustments in 24 hours, free first year post-install (€3.76 after). Old meters? Up to a week wait and €36.80 fee.
Savings: €69.55 (€32.75 + €36.80)
