The unit is capable of measuring sound, light, temperature, humidity and
particles. External monitoring features include water, gas and electricity
metering via pulse and Modbus RTU RS485 connectivity. Data collection is done through the HILTOP platform or a LoRa enabled gateway (see related products and accessories).

Data can be viewed through an interactive screen on our HILTOP and used for building automation. We also offer cloud based data hosting and visual dashboards running Grafana (A powerful Open source platform).

InfluxDB database and Grafana analytics hosting can be setup on your own local server or hosted in the cloud. Devtank offer monthly cloud hosting and data analytics service contracts starting from £30/month. Access your data from anywhere for a low monthly fee or manage it yourself.
