the cistern, the night-time leak and each unit’s consumption: what you split by square meter today, measured.
Today water, gas and power arrive on one bill in the center’s name and get split by square meter. AstreaIoT watches the cistern and the rooftop tanks, alerts you to water moving at night and measures each unit’s consumption from its meter, so your center splits what it already pays with data.

water first, then gas, chilled water and power.
Water is the way in: it is what gets lost most without anyone seeing it. Gas, chilled water and each unit’s power come next, on the same gateway. You decide what gets split and how; the platform gives you each unit’s consumption.

With the center closed, night-time consumption should be zero. If the meter shows water at the hour of lowest use, night after night, it is a slow leak.

unit 4 · m³ per month, 6 months · example
The empty unit pays for water and power it does not use.
With each unit’s consumption from its meter, the bill is split by what each one used: the empty unit stops carrying the restaurant’s share.
water this month, same m² · office 6 m³, restaurant 41 m³ · example
The restaurant uses more water than the office next door and pays the same.
Each unit’s consumption, month over month and against its own history. The difference shows on the screen and on the statement, not in an argument.
A unit’s kitchen and the gas truck’s invoice.
The pulse of each kitchen’s gas meter, totaled over the month: gas is split by what went through each meter.
The center’s chiller cools a restaurant and nobody measures it.
The chilled-water meter on the unit’s line, read from its output: the split by what went through. If thermal energy with a certified meter is needed, it is per project.
What the main meter shows and no unit explains.
The main meter minus the sum of the units: the common-area remainder, on its own line of the statement, so it is not split blindly.

the statement, every month.
A monthly statement per unit, with its water, gas, chilled water and power consumption. Your center reviews it and sends it; the remainder goes on its own line. We measure; the center is the one that bills the tenant.
The month-end close.
The platform builds a statement per unit with the period’s consumption. Your team reviews it, approves it and sends it to each tenant.
A tenant asks why their consumption went up.
The statement comes from their meter’s day-by-day record: you answer with their own curve.

chosen
The center or building where it hurts most: the cistern that runs dry, the bill nobody understands or the split that starts arguments.
site survey
what is watched
What is watched and where, with the bill in hand and the main panel located: how many units, which meters have an output and which need one next to them.
installation
2–7 days per site
A level sensor on the cistern and rooftop tanks, readings from each unit’s meters, detectors in the machine rooms and the gateway. No civil works: where a meter has no output, the new one goes on the same line. You see it on screen before we leave.
sixty days
report and close
The site watched from day one, the day-by-day baseline and two monthly reports. With that you decide the next site.
To start, the center needs its bill, the main panel located, a technical contact and one for the alerts, and a spot with power and cellular signal for the gateway.
The rule: splitting is not reselling. Selling kWh or m³ is a regulated activity; we measure and your center splits, at cost, what it already pays. The CFE and water-utility meters are still the ones that bill, and their seals are never touched.
who we are.
AstreaIoT is the monitoring platform of Astrea Technologies, an engineering and software company in Monterrey since 2018. The sensor network is ours, we build the platform and the app, and the hardware comes from manufacturers we work with directly. We install in northern Mexico with our own team and in the rest of the country with partner integrators.
No. It is splitting, at cost, the bill the center already pays, by what each unit used. Selling kWh or m³ is a regulated activity: we measure and your center splits.
Do the units’ meters have to be replaced?+
Not always. Where the meter already has a pulse output, we read that one. Where it does not, we put one next to it. The site survey says which is which before the quote.
Is the CFE meter touched?+
No. The CFE meter is the one that bills and its seals are never touched. We measure on the center’s side, at the panel, to split the bill among the units.
Who sends each unit its statement?+
Your center. The platform builds the monthly statement per unit; your team reviews it and sends it. We do not bill your tenants.
And the cistern level?+
It comes in from the first site: a level sensor on the lid of the cistern and the rooftop tanks.
What happens if the center loses internet?+
The gateway stores the readings while there is no connection and uploads them when it comes back. The sensors keep recording and everything syncs on reconnect.
the next bill is already split with data.
Thirty minutes. You tell us how many units your center has, which services you split today and how. We propose the first site and what gets watched in its sixty days.
