Shelly 3EM features unmatched Wi-Fi energy measurement technology and free energy consumption data storage.

2021, May 25 – Allterco (BSE: A4L), makers of the IoT brand Shelly,
announced that their smart power metering device Shelly 3EM has been awarded Category Winner at EC&M Product of the Year 2021 awards for Monitoring and Control Equipment,
proving to be the ultimate automation product suitable for installation and use in residential, commercial, and
industrial applications. Developed in collaboration with Analog Devices,
– a leading global high-performance semiconductor company, Shelly 3EM allows precise energy monitoring and
provides control for improved energy savings.

Meeting a long list of criteria, Shelly 3EM won over the hand-picked panel of judges who ranked this year’s Product of the
contestants based on a uniform list of scoring standards, ultimately selecting 31 category winners for the
first phase of the competition. Each category winner will then compete for 1st, 2nd and 3rd place through an online poll
available on the EC&M website.

Giving owners enhanced safety and everyday control over appliances or machinery, along with the ability to make smart
decisions about electrical consumption, Shelly 3EM heads the Monitoring and Control Equipment category thanks to its
Wi-Fi connected energy measurement technology and 10-amp contactor control, monitoring up to three phases between 110
and 240v per line.

With full energy consumption data free Cloud storage, Shelly 3EM is ideal for sub-metering, solar, appliance metering,
and control via contactor, residential, or industrial safety shut-offs – thanks to individual channels independent
control. It supports REST API, CoAP, MQTT, and Cloud API out of the box, allowing the connection of the device to home
automation platforms including Amazon Alexa, Google Home, SmartThings, Home Assistant and others.

“Shelly 3EM is a complex product, it is the outcome of many tests and numerous improvements. It is a great pleasure to
see the efforts we put into the product being recognized by EC&M as their Product of the Year 2021” says
Dimitar Dimitrov, CEO of Allterco.
“A dedicated energy metering IC can perform the power monitoring
functions in hardware, using significantly less power than a microcontroller doing the same thing in software. Shelly
3EM uses an architecture consisting of a smaller, lower-power microcontroller for system management, linked to an Analog Devices energy metering IC. This
provides the best of both worlds: accurate, high-performance energy measurement, consistent with the Shelly brand
promise of professional grade smart home metering, and low bill-of-materials cost so that Allterco can price the product
at an affordable level for the DIY user.”

“Analog Devices is committed to delivering high-accuracy energy measurement solutions that offer exceptional
functionality and are easy-to-use”, said Conor Power, Director of the Energy Business Unit at Analog
“We are pleased to collaborate with Allterco in enabling innovative, cost-effective products that
enable consumers and businesses to realize energy savings through continuous monitoring and control of devices in the
home and the workplace.”

Established in 2001, the EC&M Product of the Year competition recognizes excellence in new product development for
the electrical industry. Honoring inventiveness in product design, as well as improvements in safety and efficiency, the
competition’s two-fold judging and voting process determines the most ground-breaking products of the past year that
allow electrical design professionals, installers, and maintenance personnel to perform their jobs more efficiently and
