After a quite busy period of tests and trials, the new version of openzmeter in its three-phase variant is here. Its development is a major step forward towards the reinforcement of the project and we believe that it will allow us to reach a larger number of people. Following the same philosophy as in single-phase

Upgrade firmware for old oZm versions
The old versions based on Debian images can be upgraded to newest based on OpenWRT. The procedure is simple, but be very careful!. 😛 WARNING: All your information will be lost!!! Uncompress and flash the .img.gz file on a microSD. Power off the ozm and remove the power supply. Extract the NanoPI board from ozm

Single phase circuits basics
Single-phase alternating current (AC) is a main technology for efficient energy delivery across the world. Among its uses are lighting, low power electric motors or heating. It is characterized by a sinusoidal shape and varies in time so that the same pattern is continuously repeated. This energy system is characterized by a voltage with the

openZmeter in the press
We are pleased to announce that openZmeter has been noticed by the local mediafor the first time. Five local digital newspapers published about us and our labour at university (Universidad de AlmerÃa, Spain). Our university digital newspaper was the first one to publish an article about openZmeter and, within a week, four more local media

Paper published in journal Sensors (MDPI)
This is the second specific paper on the openzmeter device. It describes in detail its hardware architecture and provides measurements in a real scenario. Likewise, a comparison is made with commercial and professional devices that reveals the accuracy of the measurements obtained according to international standards. Cite as: Viciana, E.; Alcayde, A.; Montoya, F.G.; Baños,

First scientific paper published
The openZmeter team is completely delighted again. Recently, a new scientific article has been published in the prestigious journal Sustainability edited by MDPI. Our Ph.D. Student Eduardo Viciana did a great job and the result is his first international paper entitled “OpenZmeter: An Efficient Low-Cost Energy Smart Meter and Power Quality Analyzer”. It is open

Some History about oZm (III)
This is the third and final entry about the OpenZmeter project history. You can read the first one here and the second one here. After the first sketches and designs based on the BBB and own electronics (something homemade… everything is said), there was a step forward in quality with the arrival of Eduardo Viciana
