How to read gas from your mobile to avoid billing errors

26 mayo, 2021

With the current confinement situation, many households are not being visited in person to carry out the regular registration of the gas meter. This, added to the problems that there may be at the level of saturation of telephone lines in the gas companies themselves, favors solutions such as the one that we are going to detail below: do the gas reading ourselves and send it from the mobile phone.

The method that we are going to use is valid with the two large gas trading companies: Endesa and Gas Natural Fenosa (now Naturgy). In fact, Marketers such as Endesa are recommending this method via email to avoid making estimated readings and being able to collect the actual invoice.

Reading from the mobile

My accountant The first thing is going to be to register the CUPS of the meter. This number is found on your gas bill, reflected as ‘CUPS Code’.

To use this app it will be necessary to have access to the gas meterOtherwise, we will not be able to see the reading. Once we have verified that we have access, the first thing we have to do is download the YoLeoGas app. It is the application itself that Endesa is recommending to its customers and, in our case, we have been able to test it successfully by sending data that has been correctly read by the company.

The first thing we have to do is register the CUPS code of our gas bill. The obvious question here is, What is and where is this CUPS code? CUPS stands for Unified Supply Point Code and has the objective of identifying each power supply point.


You will find it on your gas bill, depending on your distributor and type of invoice. It is easy to find as it clearly says ‘CUPS code’. In our case, with an Energy XXI (Endesa) invoice, the data can be found in the ‘Contract Data’ section, although the application itself gives us possible locations of this CUPS code.

Once we have copied the CUPS we paste it into the application. If you recognize it as the identifier of a compatible marketer, we can proceed to read

Once we have it pointed out, we only have to name the counter (whatever we want, this is simply to have it saved ourselves) and introduce CUPS. For example, you can put ‘My counter’, enter the code and have it saved.

When we have saved the code, the app will invite us to take the first photo. We must go to where the counter is and try to square the photo as much as possible. The app has an automatic mode that it shows us the interface in green when the image has been correctly detected. When this happens, we take the photo.

Reading Before sending the photo we must make sure that all black numbers are recognized. Reds do not apply.

After doing this, the numbers that have been recognized in the reading will be indicated. We recommend not sending the reading until all the numbers (black) are recognized, without any interrogations in any of them. If we consider that the photograph is of good quality and we have made sure that all the numbers correspond to what you put on the counter, we can now send a reading.

Finally, note that it is the user’s responsibility to send the reading on time. That is, the application assures us that the photograph with the actual reading reaches the distributor, but if it has already made the estimated reading, it will be of little use. The app is an intermediary between users and the distributor itself, so it is not responsible for the distributor, in case of error, making the estimated reading.
