Deploy faster with resilient, robust and affordable IoT infrastructure

Our groundbreaking Industrial Internet of Things (IoT) platform enables rapid site deployment and same-day data visualisation, without the need for specialised expertise. The key to deploying energy monitoring systems to more sites, more quickly – is a monitoring system that can configure and troubleshoot itself automatically, and a hardened industrial product range that keeps running, even in the most demanding environments.

Why do our customers choose to work with us?

EpiSensor systems have a unique combination of features and qualities that make them suitable for use in the most secure, harsh, commercial and industrial environments, while maintaining ease of installation and flexibility.

Easy to Use

Our systems are designed from the ground up to be easy to install and use. Plug in our Gateway, go to a website from your laptop, phone or tablet, and start building.

Fully Secure

The data produced by our systems is often highly sensitive, and can directly relate to production levels, environmental conditions or occupancy. Our systems are fully secure from sensor to server.


Data loss should never be acceptable. If there is a communications or power failure, our devices will log years of time-stamped data until the connection is restored.


Deploy a small system with a single sensor or a city-wide communications infrastructure. Our systems will scale gracefully, and expand as your monitoring requirements do.

Standards Based

We export data in open formats such as CSV, XML and JSON. This is essential if you need to integrate with enterprise systems, or simply decide to change software vendor.

Long Battery Life

We have spent years in the lab perfecting the low power electronics techniques used in our battery powered sensors. 10 year battery life means little or no maintenance costs.


When reducing energy usage, sometimes by single figure % points, it’s essential that the data you collect is accurate. Our electricity meters are accurate to Class 1 (+/- 1%).


Our product enclosures are waterproof as standard. Install indoors, outdoors, in clean, dirty or harsh environments – that’s one less design constraint to think about.

Developer Friendly

We produce accurate, real-time data in open formats – our systems are documented and designed to be integrated with. Start building exciting new applications today.
