Commercial building management —
without the commercial price tag.
Thermofi cuts heating and cooling waste in small commercial buildings — without replacing a single piece of HVAC equipment. Drop-in install, AI-tuned, and you only pay when we deliver.

Most thermostats drive your HVAC
like it's a drag race.
Conventional thermostats overshoot, undershoot, and cycle equipment far more than necessary — burning extra fuel and wearing equipment out years ahead of schedule. Watch what's actually happening inside the wall:
Wide deadband, no learning. Constant overshoot wastes fuel; constant cycling destroys equipment.
Sensors + weather + AI find the longest, gentlest run that holds your target — comfort up, bills down, equipment protected.
Everything in a commercial BMS —
built for small buildings.
Thermofi is a full-stack climate platform: customer self-service, installer tools, automated control, and device-level monitoring. Here's what's in production today.
Monitoring & visibility
Multi-building, multi-zone dashboard with live thermostat state, room and pipe sensors, occupancy rollups, 24-hour history charts, outdoor weather, and per-device alarm status.
Scheduling & automation
Customers set weekly occupied hours and heat/cool targets. Automated logic runs predictive preheat and precool, presence overrides, and multi-thermostat zones — without wiping manual adjustments.
Occupancy
Presence sensors per room with zone-level aggregation for setbacks and unoccupied overrides. Supplemental CO₂-based detection where deployed.
Direct control
Change mode, setpoints, and deadband from the web console — applied to every thermostat in the zone.
Device platform
Fleet provisioning with SMS OTP, over-the-air firmware updates, high-resolution time-series telemetry storage, and remote device logging.
Installer tools
Admin console for deadbands, thermal models, device assignment, and engineering schedules — with links into the customer dashboard for support.
Hardware
Four drop-in devices — three sensor types plus a thermostat controller. Install over your existing HVAC; no rip-and-replace.
Room temperature sensor
Per-room air readings that feed zone averages and thermostat control across the building.
Pipe sensor
Supply, return, or immersion temperatures — boiler health, freeze risk, and equipment monitoring.
Occupancy sensor
Detects when a space is truly occupied for setbacks and schedule overrides — including still occupants that motion PIRs miss.
Thermostat
Wires into conventional residential thermostat connections (R, W, Y, G) for furnaces, boilers, and heat pumps. Calls for heat or cooling against room sensors. The cool relay can drive window AC units and mini-splits — not just central plant.
All devices self-provision over Wi‑Fi, receive over-the-air updates, and stream telemetry into the platform continuously.
Ten alarms
Every device gets automatic alarms at registration — room, pipe, occupancy, and thermostat. Status shows in the customer console so problems surface before tenants call.

Optional SMS alerts (building-wide temperature, duty cycle, device availability) are configured separately per customer.
Lower bills, longer equipment life,
and control from anywhere.
Thermofi turns your existing HVAC into an intelligent, networked system — so you can save money without replacing equipment, and manage every zone from your phone.
Our models learn your building's thermal personality — insulation, sun exposure, occupancy patterns — then time every heat and cool cycle for maximum efficiency.
Adjust setpoints, schedules, and modes from the web or mobile app. Get alerts the moment equipment behavior deviates from norms — before tenants notice.
By eliminating short-cycling, Thermofi dramatically reduces wear on your boiler, compressor, or RTU — pushing capital replacement years into the future.
Pay only when we deliver.
Our offer is simple: prove the savings with a free pilot, then your first year is capped at the dollars we actually save you. If we save you nothing, you pay nothing.
Risk-free assessment of your building's HVAC inefficiency.
