Built for the realities of HVAC service.
A sensor your technician installs in a maintenance visit. A portal your office watches. An alert that names the failure before the customer calls.
One maintenance visit. No homeowner homework.
- 01 The sensor mounts to the furnace cabinet — no modifications to the furnace.
- 02 It powers from the furnace’s own 24V transformer, with battery ride-through. No batteries to change, no wall wart to find an outlet for.
- 03 It senses the heat call directly from the thermostat wires, so it always knows what the furnace was asked to do.
- 04 Wi-Fi is configured before the unit ships, so on site it’s mount, land the low-voltage connections, and go.
Every feature has a job on a service desk.
Watches the furnace itself
The sensor mounts on the furnace cabinet and follows every heating cycle — the heat call from the thermostat wires, and the mechanical activity of the inducer, ignition, and blower.
Names the failure
When a cycle goes wrong, the failure gets a name — heat call with no ignition, igniter failure, flame sensor failure, a pressure switch or rollout trip, short cycling — not just an “error” light.
Detection on the sensor
Classification runs on the device itself. A Wi-Fi drop at the home never means an unwatched furnace, and the portal flags any sensor that stops reporting.
Push alerts to your team
The moment a failure is identified, a push notification lands on your team’s phones with the failure mode and the timeline.
Fleet view and health scores
Every monitored furnace in one list, with two health scores per unit — the furnace and the sensor watching it — and cycle history for context before the truck rolls.
Customer logins, scoped
Homeowners and property managers can sign in and see only their own equipment, under your company’s service. Your fleet stays yours.
Enough to load the truck.
Heat call with no ignition — Furnace 07
Thermostat calling for heat since 5:42 AM. Inducer not detected, ignition not detected. Last normal cycle completed 11:20 PM.
The dispatcher sees the failure mode and the timeline before assigning the truck. The technician walks in already knowing what failed. See the full list of what it catches.
