The new meters from the Federal Electricity Commission (CFE) with connection Bluetooth They are poised to change how households interact with their electricity consumption. These digital devices, still under development and being rolled out gradually, combine remote reading, remote control, and direct communication with the user via mobile phone.
Beyond the technological component, the initiative is part of a broader strategy modernization of the measurement and billing systemCFE aims to improve the accuracy of meter readings, facilitate the detection of faults and fraud, and offer tools that allow users to have detailed information about their electricity consumption without waiting for the bimonthly bill.
What are the new Bluetooth light meters and how do they work?
The so-called smart meters with bluetooth technology These are electronic devices capable of recording energy consumption automatically and with high precision. They differ from traditional meters, whether rotating disc or basic digital, in that they integrate two-way communication functions and do not require periodic visits from a technician to take readings.
These devices are part of an advanced metering infrastructure similar to the systems already being implemented in various European countries, where meters are remotely connected to control centers. In the case of CFE, the Bluetooth connectivity It allows data exchange to take place without physical access to the meter, facilitating both technical supervision and user interaction.
On a daily basis, the meter records in real time how much electricity is being used in the home and stores a very detailed consumption history. This information is transmitted periodically to the CFE's systems, making it possible to identify demand spikes, sudden changes, or anomalous behavior that might have gone unnoticed before when only one reading was taken every so often.
In addition to measurement, these devices incorporate functions of remote supply managementFrom a control center, disconnections and reconnections can be ordered without an operator having to travel to the meter, something especially useful in buildings, communities or facilities where the meters are located in closed rooms or hard-to-reach areas.
This combination of continuous recording, wireless communication and remote operation capability puts Bluetooth-enabled meters on par with smart meters deployed in much of Europe, where digital metering is already the basis of the relationship between distributors and customers.
Control consumption from your mobile phone and smart home assistants
One of the most visible changes for the user is the possibility of Check your electricity consumption from your mobile phone or by applications for Androidor even through virtual assistants like Alexa or Google Assistant. The idea is for the meter to stop being a device hidden in a box and become integrated into the home's ecosystem of connected devices.
CFE envisions the meter being linked to official applications—such as the already familiar CFE Contigo—to display consumption in near real-time. This way, instead of waiting for the bill to see how much they've spent, customers could monitor their electricity usage daily or even hourly.
Having detailed data makes it easier for each person to adapt their habits. By clearly seeing when consumption spikes and which routines increase the bill, it becomes easier to make decisions, such as disconnect equipment on standbyAvoid leaving appliances switched on when not in use, or shift certain uses to more convenient times if more dynamic time-of-use tariffs become widespread in the future.
Integration with smart home assistants opens the door to additional features, such as asking how much energy has been consumed in the month, receiving alerts when a certain spending threshold is exceeded, or requesting information about service outages. All of this makes managing electricity more user-friendly and intuitive for the average person.
This type of direct access to information is reminiscent of the approach taken in several European Union countries, where smart meters allow households to monitor their consumption through digital platforms, which is key to promoting more efficient energy use.
Changes to the electricity bill and relationship with the electricity company
One of the most common questions is whether installing these meters will make the electricity bill cheaper. On their own, the meters with Bluetooth does not change the rates nor the price of energy, but they do change the way in which what is paid each period is calculated.
With the new equipment, billing is based almost exclusively on the actual consumption recorded by the devices, minimizing estimates and human error in reading. This may result in adjustments up or down compared to what was previously paid, depending on whether the initial estimates were higher or lower than the actual consumption.
The big difference for the customer is the greater transparency of the receiptEvery kWh consumed is fully recorded, so the figure on the bill is backed by a detailed and verifiable history. This reduces the feeling of an "approximate number" that sometimes fueled doubts or complaints.
For CFE, digitalization also means more efficient management of new service connections, disconnections, service interruptions for non-payment, and reconnections after the situation is resolved. By being able to remotely manage the supply, response times are shortened, both for suspending service when there is an outstanding balance and for restoring it once the problem is resolved.
This model aligns with what is already happening in many European networks, where remote reading and management from control centers are the norm. There, smart meters have helped reduce complaints, improve measurement accuracy, and better coordinate response to incidents.
Installation, deadlines and what the user needs to do
The deployment of Bluetooth-enabled light meters is being carried out in a gradual and by zonesAs of today, there is no single date when all households will have these types of devices, and the CFE has insisted that the project is still in the development and testing phase.
When the changeover reaches a specific area, the replacement will be part of the overall network modernization strategy, so subscribers will not need to request the new meter individually. The procedure will be carried out by authorized personnel, who will remove the old meter and install the new one in its place.
In principle, no major modifications to the electrical wiring inside homes are expected. Even so, it is advisable for residents to verify the identity of the technicians who come to carry out the replacement, in order to avoid potential fraud or unauthorized actions that might use the meter change as a pretext.
After installation, it's a good idea to carefully review the first few bills. Comparing consumption and amounts with previous periods helps detect any discrepancies. If you have any doubts, it's wise to... contact the company directly to check the meter settings or the way the expense is being recorded.
CFE itself has indicated that the implementation will be phased and subject to technological evolution and the availability of infrastructure, a similar approach to that of most European countries, where meter replacements have been planned in phases that often last for several years.
Direct advantages at home: convenience, precision and fault response
Beyond the technical aspects, these meters offer practical advantages in everyday household life. The first is the comfort: there is no longer a need to wait for a meter reader to arrive, open gates or coordinate schedules for someone to access the meter, something that in some buildings became a recurring nuisance.
Another clear advantage is the reduction in reading errors. By automating the process and relying less on manual entries, there are fewer instances of unusually high or low invoices due to human error. This translates into fewer complaints and less time wasted resolving discrepancies.
The availability of near real-time data also allows users to have much finer control over their consumption. Through apps and digital tools, it's possible to set goals—such as staying below a certain monthly spending level—and check on the fly whether they are being met, adjusting electricity use as needed.
It also improves the management of incidentsWith a network of connected meters that constantly transmit data, the company can detect supply outages, overloads, or other unusual behavior without relying solely on customer calls. This allows for earlier intervention, better pinpointing the source of problems, and reducing service interruptions.
This approach aligns with the experiences of various European distributors, who have used smart meters as sensors distributed throughout the network, improving visibility into what is happening in each section and anticipating failures that were previously only detected when they already affected a large number of users.
Fight against “diablitos” and electricity fraud
One of the clearest objectives of the new generation of meters is limit illegal connections And meter tampering, a problem that generates significant losses and impacts grid stability. These well-known alterations or "diablitos" (illegal electricity connections) have long been a challenge for electric companies, and digitalization offers more effective tools to combat them.
Bluetooth-enabled meters incorporate sensors that detect openings, impacts, attempts at internal tampering, or unusual changes in energy flow. If someone tries to lift the cover, access the electronics, or bypass the wires, the device itself records the event and reports it to the CFE (Federal Electricity Commission) systems, generating an alert that can be analyzed in detail.
Since these devices are entirely electronic, it's no longer possible to use tricks that worked with older meters, such as placing magnets to slow down the mechanism. Any interference of this kind results in measurable anomalies, and the meter is then primed to act as a kind of “black box” that keeps a record of what happened.
Another key tool is the energy balance between the output of a transformer and the readings of the various meters connected to it. If the difference is significant, the systems can pinpoint the section where losses are occurring and focus the inspection there—a technique also used in European networks to reduce fraud and non-technical losses.
When deliberate tampering is confirmed, the company has time-stamped technical evidence, which facilitates recalculating consumption or imposing penalties in the most serious cases. Furthermore, if the incident requires it, the system allows for remote service interruption without waiting for a technician to physically travel to the site.
A step within a broader digitization strategy
Bluetooth-enabled meters are not an isolated component, but part of a system. broader process of technological modernization within CFE. The company is integrating data analytics systems, network automation, and predictive platforms to anticipate problems and improve service quality.
Among the initiatives underway are tools that cross-reference consumption data with meteorological information to predict potential impacts from storms, cold fronts, or other phenomena that could lead to power outages. The goal is to strengthen response capacity and reduce the time users are without power.
Automation systems are also being deployed that can isolate specific areas when a fault is detected, preventing a localized problem from affecting wider areas. In this context, smart meters act as distributed sensors that help to see in greater detail what is happening at each point in the electrical system.
Although the project described is being driven by CFE in Mexico, the approach is very similar to that of numerous European countries that have been massively replacing traditional meters with smart meters for years. In all cases, the roadmap points in the same direction: improve efficiency, reduce losses, increase user control and prepare the network for a more digitized and connected future.
Overall, the arrival of Bluetooth-enabled electricity meters marks a turning point in electricity supply management: it doesn't guarantee cheaper bills on its own, but it does bring users closer to their actual consumption, facilitates finer control of spending, and provides the company with more precise tools to monitor the network, react to failures, and prevent fraud, following a trend that is already common in much of Europe and other advanced markets.
