Software

Precise, infinite energy data. Made for control freaks.

Never worry about the heat (or heat complaints) again. S2’s high-tech software works in tandem with physical sensors for precise control. Access the S2 app from your computer, your phone, or within the boiler room!

S2 unlocks high-level data that helps thousands of clients save time and money.

We get wrongful tenant complaints. Now I just pull up the accurate data on S2 in seconds and bring it to court.

Michael M., Property Owner

I check the graphs and reports every day to keep track of heating and find problems before they get expensive.

Solomon T., Property Owner

The graphs are outstanding. When issues arise we can easily review building temperatures.

Mark L., Property Owner

I can use the data to determine that one line of apartments is substantially colder than others.

David L., Property Manager

I use the reports regularly during heating season to pinpoint any issues that we may be having. Great tool!

Marcus R., Property Manager

For me, data is key to my job. The S2’s reports are essential.

Levy G., Property Manager

DASHBOARD

One glance and you’re a know-it-all.

The S2 dash displays medium apartment temp, water loss, heat runtime, alerts, utility usage, and weather. It also links to your city’s compliance agency so that you can monitor tenant complaints from the app.

CYCLES + THERMA AI

Manage, observe, and override heat cycles.

Get a bird’s-eye view of your building’s space sensors, control for equation-disrupting anomalies, view 24-hour cycle histories, and set different schedules for weekdays, weekends, and holidays. Lock, override, and reset heat cycles whenever you wish.

alerts & notifications
alerts & notifications

Know what’s happening before it happens.

Escalating temperatures, high water pressure, boiler leaks and so much more: get notifications and fix problems before they get out of control.

S2 snapshot

Check in on your
boiler room.

Check in on your boiler room. See wifi connectivity and monitor the boiler sensors: aqua, coil, mix, and water loss. Adjust boiler status, view history, and so much more. The snapshot is useful whether you have multiple buildings to monitor — or just one.

graphs & reporting

Get the full picture with infinite energy reports.

Change graph views, export reports, and filter for accurate reporting. Even better? Take those clear historical reports to the bank for financing — and to the courtroom.

Cutting-edge tech for blazingly fast, blazingly smart boiler controls.

THERMA AI

Leave the math to the machines

Manually modulating proper indoor temperatures is tricky. Therma AI utilizes machine learning to auto-calculate the temp and timing based on sensor input and routinely self-adjust to maintain temperature.

By running fewer heat cycles, Therma AI minimizes energy costs and gives you a much clearer look at your energy data – saving an additional 10% on top of S2’s savings.

S2, safe and secure

S2 runs wirelessly over your building’s wifi network, maintaining connection to sensors and accessible from anywhere. No wifi? Ethernet cable connections work as well. Plus, S2 is always online: a network of redundant servers guarantees 99.99% uptime.

control & customizability

One fast, flexible command center

With S2’s infinite configurations, you’re in control. Change temps based on average or majority readings, create rulesets to group similar zones together, and assign unique variables (like cold lines or sensitive tenants) to override rules and gain even more control. Adjust weekend and holiday setpoints, maintain special schedules, override heat cycles, and more!

Powerful, beautiful — everywhere.
