These advances give rise to the need for new media devices with remote communication, and require a greater control and monitoring of the state of the electrical grid in order to verify its correct state, as well as the detection of faults or alterations that are occurring in it due to these new generation systems or new loads. These remote, unsupervised measurement devices require galvanic isolation to protect the measurement and communication system, so that even if there is a break in the isolation, the integrity of the measurement and communication system is maintained. In addition, as it is a device prepared for multipoint measurement, the cost of the probe must be contained. This article details the design, implementation, and validation of a low-cost remote isolated differential voltage probe. This probe is intended for monitoring at network supply points, as well as for the verification of the European standard EN 50160 as a means of detecting disturbances in network behaviour. Its characteristics as a differential and isolated probe provide it with the possibility of floating voltage averaging, guaranteeing the integrity of the electronics of the low-voltage probe, i.e., the digitalisation and communication system. The measurements collected are sent via an MQTT protocol, which makes the remote probe a device compatible with the Internet of Energy. For the validation of the probe, a full functional test is performed, including FFT spectral analysis to verify the compliance of the mains voltage with the aforementioned European standard EN 50160. 000132166 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/PID2019-106570RB-I00$$9info:eu-repo/grantAgreement/ES/MICINN/PID2022-138785OB-I00 000132166 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000132166 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000132166 700__ $$0(orcid)0000-0002-3302-7862$$aPérez-Cebolla, Francisco José$$uUniversidad de Zaragoza 000132166 700__ $$0(orcid)0000-0001-5709-1183$$aEnériz, Daniel$$uUniversidad de Zaragoza 000132166 700__ $$0(orcid)0000-0003-2361-1077$$aCalvo, Belén$$uUniversidad de Zaragoza 000132166 700__ $$0(orcid)0000-0002-5380-3013$$aMedrano, Nicolás$$uUniversidad de Zaragoza 000132166 7102_ $$15008$$2785$$aUniversidad de Zaragoza$$bDpto.
