Every site depends on mains, generators, DC power and fuel, often with nobody there to watch them. En-Stream brings ATS readings, breaker status, DC current, fuel levels and panel alarms from every location into one live view, and alerts your team the moment something changes.

A tripped breaker, a failed changeover or a generator that won't start is often discovered only when the site goes down.
Diesel is bought for every generator, but without tank levels it's hard to tell consumption from refills, and refills from pilferage.
Doors on power and DC panels are opened, and smoke or heat builds up, without anyone knowing until the next visit.
Checking meters, tanks and panels in person across many sites is slow and expensive, and still leaves gaps between visits.
En-Stream reads these from ATS panels, meters and DC panels, or from sensors and contacts wired to a gateway.
Line voltages, phase currents, power per phase, frequency and energy, for both the utility supply and the generator.
Which incomers and load breakers are on, off or tripped, and whether the site is running on mains or generator.
Level, litres available, consumption, refills and pilferage, for underground tanks and generator tanks.
Current on every shunt across your DC panels, so the DC load is visible panel by panel.
Front and back door status, smoke alarms, temperature and humidity for each AC and DC panel.
Current, kW, kVA and voltage graphs, to spot load growth and supply problems early.


ATS readings, panel status, fuel tanks and DC shunts, each on its own screen, laid out the way your sites are wired.


Alarms on breaker trips, mains failure, low fuel, a drop in tank level, open doors, smoke or high temperature, sent the moment they happen.
Grid, generator and solar feeding each site, live, and which source carries the load.

The ES-IGW-B1 reads ATS panels, energy meters and other Modbus devices over Modbus TCP and RS485.

The ES-IGW-E1 adds direct inputs: door contacts, smoke alarms and breaker status on its digital inputs, and temperature, humidity and fuel level sensors on its 0–20 mA / 0–10 V inputs.
Yes. Tank monitoring tracks the level, consumption and refills of each tank and flags pilferage, so fuel that leaves the tank without being used shows up straight away.
Yes. ATS readings and breaker status show which source is feeding the site, and alarms tell your team when it changes over or a breaker trips.
Yes. It reads the current on each DC shunt, panel by panel, alongside the AC readings from the ATS.
Yes. Every site reports to the same platform, and remote access lets your team open any site's dashboards from any device.
Gateways send data, encrypted, to the platform over Ethernet, Wi-Fi or GSM.
