Jellyfish smart metering solves data challenges

Jellyfish clips on to existing water meters, which are typically in underground chambers and do not easily connect to 4G, 5G or WiFi. Jellyfish gets around this problem by connecting wirelessly over 0G, a low-power technology from Sigfox.

We are on a mission to redefine smart water metering

The latest predictions estimate that if further action is not taken, between 2025 and 2050 we’ll need more than 3.4 billion additional litres of water per day to meet future demand for public water supply.

The latest goverment framework introduces an ambitious aim for water companies to help consumers cut wastage and to use water more wisely in order to reduce our average water use from 143 to 110 litres per day.

We provide predictive maintenance smart IOT solutions and machine learning software that help water companies capture continuous data and physical insights, enabling smarter decisions for them and their customers.
