The Linky smart meter has become a symbol of controversy in France. Presented as a technological revolution by Enedis (France's electricity distribution network operator), it is accused by its critics of causing fires, outages, overbilling, and raising serious privacy questions.

This article provides a factual overview of known problems associated with Linky meters, presenting both sides: Enedis's position and that of its critics.

The Massive Deployment

35 million meters installed in 10 years: France's largest IoT deployment.

The Programme in Numbers

Enedis's Promises

Enedis presented the Linky as a revolution:

For the consumer:

• Automatic meter reading (no more technician visits)
• Real-time consumption monitoring
• Remote operations (activation, power level changes)
• Billing based on actual consumption

For the grid:

• Faster outage detection
• Distribution optimisation
• Renewable energy integration
• Preparation for the "smart grid"

The Critics' Reality

From the very beginning of deployment, voices were raised:

• Consumer associations
• Anti-Linky collectives
• Local elected officials
• Independent experts

Criticism centres on four main areas:

1. Safety (fires, overheating)
2. Privacy (consumption data)
3. Health (electromagnetic waves)
4. Finances (overbilling)

The Fires: The Facts

Dozens of fires documented by fire brigades: Enedis minimises, the SDIS (fire and rescue services) testify.

Documented Cases

Incidents involving Linky meters have been reported by fire brigades, local media, and consumer associations:

Documented examples:

• Fires requiring fire brigade intervention
• Melted or charred meters
• Fire outbreaks in electrical panels
• Significant property damage

Identified Causes

Several factors have been highlighted:

1. Connection Defects

• Insufficient cable tightening during installation
• Defective connection terminals
• Progressive contact overheating

2. Overheating During Peak Loads

• Poorly calibrated power limitation
• Local grid overload
• Heat dissipation problems

3. Component Quality

• Questions about materials used
• Mass production at low cost
• Quality control criticised

4. Installation Problems

• Not always qualified personnel
• High installation rates
• Insufficient verification checks

Enedis's Position

Enedis minimises the incidents:

"The incident rate on Linky meters is extremely low, lower than that of older meters."

-- Official Enedis communication

The operator claims:

• Incidents are rare (<0.01%)
• Most are due to pre-existing faulty installations
• Linky meters are safer than older ones
• Safety standards are fully met

What the Critics Say

Consumer associations contest this narrative:

"Enedis refuses to disclose the real incident figures. The fire brigades, however, see the fires and know where they start."

-- Robin des Toits Association

Points raised:

• Opacity regarding the actual number of incidents
• Refusal to release detailed statistics
• Systematic minimisation
• Pressure on experts who speak out

The Safety Glass Change

Bulletproof glass quietly replaced by less fire-resistant material.

The Revelation

Reports have flagged a discreet component change:

What allegedly changed:

• Original bulletproof glass panels replaced
• New material less resistant to fire
• Modification not publicly communicated
• Suspected economic motivations

The Implications

If this change is confirmed, the consequences are concerning:

Enedis's Response

Enedis disputes these accusations:

• All meters comply with current standards
• Modifications are normal technical evolutions
• Safety is not compromised
• Certification tests have been passed

The Ongoing Investigation

Several questions remain:

• What are the exact specifications of the different production series?
• Have there been substantial modifications?
• Are safety tests adapted to real-world conditions?
• Why the lack of transparency?

Overbilling Issues

Bills doubled after installation: more precise measurement or meter malfunction?

The Phenomenon

Many consumers report bill increases after Linky installation:

Possible Explanations

1. More Precise Measurement

"The old meter could underestimate consumption. The Linky measures what you actually consume."

-- Enedis

Some older meters were inaccurate in the consumer's favour.

2. Configuration Problems

• Incorrectly configured subscribed power
• Off-peak hours tariff not activated
• Options not carried over from the old contract

3. Malfunctions

• Defective meters
• Measurement errors
• Software bugs

4. Behavioural Changes

• New electrical equipment
• Remote working (COVID)
• Increased electric heating

Recourse Options

If you notice overbilling:

1. File a Complaint with Enedis

• Request a meter verification
• Analysis of detailed readings
• Comparison with historical data

2. Contact the Energy Mediator (Mediateur de l'Energie)

• Free of charge
• Independent
• Timeframe: 2 months after Enedis complaint

3. Legal Action

• Local court (tribunal de proximite)
• Prove the malfunction

Privacy Concerns

Your consumption habits reveal your presence, absences, and lifestyle.

Data Collected

The Linky meter can collect highly detailed information:

What This Data Reveals

By analysing your electricity consumption, one can deduce:

• Are you at home? (Presence/absence)
• What time do you wake up? (Coffee machine, lights)
• What appliances do you use? (Electrical signatures)
• How many people live there? (Consumption volume)
• Are you on holiday? (Prolonged drop in usage)

The Legal Framework

GDPR applies:

• Consent required for granular data
• Right to object
• Limited purposes

What Enedis can do without consent:

• Daily meter reading
• Grid management
• Billing

What requires consent:

• Hourly data
• Sharing with third parties
• Detailed analyses

The Risks

In case of a data breach:

• Habit profiling
• Burglary targeting (absences)
• Commercial discrimination
• Invasion of privacy

The Right to Refuse

The meter belongs to Enedis: legally complex, practically possible through obstruction.

The Legal Question

The meter belongs to Enedis, not the homeowner:

• Enedis is the grid operator
• The meter is part of the grid
• Access is provided for in the concession contract

Therefore, legally:

• No formal right to refuse
• But no explicit legal obligation to accept either

Methods of Resistance

Some people have managed to prevent installation:

1. Denying Access to the Premises

• If the meter is on your property
• Enedis cannot force entry
• But risk of complications (paid manual meter reading)

2. Written Opposition

• Registered letter to Enedis
• Legal argumentation
• Variable results

3. Collective Action

• Municipalities that issued decrees (overturned by courts)
• Consumer defence associations

Consequences of Refusal

International Comparison

Germany cautious, Italy a pioneer, UK problematic: smart meters elsewhere.

FAQ

Can my Linky meter catch fire?

Cases of fires linked to Linky meters have been documented, primarily due to connection or installation defects. If you notice a burning smell or abnormal heat near the meter, switch off the circuit breaker and contact the fire brigade.

Can I still refuse the Linky?

Deployment is nearly complete (95%). If you do not yet have a Linky, refusing remains difficult because the meter belongs to Enedis. However, if the meter is on your private property, you can deny access (with the risk of complications).

My bill skyrocketed after the Linky was installed -- what should I do?

Contact Enedis for a meter verification and analysis of your readings. If the response is unsatisfactory, contact the Energy Mediator (free of charge). Compare with your historical consumption data.

Does the Linky monitor my habits?

The Linky can collect detailed consumption data. Without your consent, only daily data is transmitted. Hourly data requires your explicit agreement. You can refuse the sharing of granular data.

Is Enedis liable in case of fire?

If a fire is caused by a meter defect or installation fault, Enedis can be held liable. Keep all evidence and have the fire brigade produce an official report.

Conclusion: Vigilance Required

The Linky smart meter is neither the monster described by its most vocal critics, nor the flawless innovation promoted by Enedis.

Key takeaways:

1. Incidents are documented -- fires, overheating, malfunctions
2. Transparency is lacking -- opaque statistics, controlled communication
3. Overbilling does occur -- multiple causes, recourse available
4. Privacy is at stake -- collectible data, consent required
5. Refusal remains difficult -- but not impossible in certain cases

Vigilance is essential. Monitor your meter, document any incident, and do not hesitate to assert your rights.
