What's in the box
Stop taking their word for it.
We built Squawkbox around the things that actually cost you money. It tracks every blowdown, every pressure drop, every burner controller state change so you know your boiler is being maintained.
Real-Time Alerts
Get an SMS the moment something trips in the field so your team can respond before your customer knows anything is wrong.
Remote Shutoff
Shut off a dangerous boiler from three states away. A physical bypass switch allows you to disable remote shutoff, ensuring Squawkbox cannot impact operations.
Works With Any Boiler
Retrofits onto any boiler regardless of brand or age. Connects to mechanical switches, analog sensors (4-20mA, 0-5V), and modbus devices (RS-232, RS-485).
Operational Data & Trends
Stack temperature, steam pressure, feedwater flow rates, cycle counts, and flame signal over time. Spot degradation patterns before they become expensive repairs.
Web Dashboard
Check any boiler in your fleet from anywhere. Real-time status, alarm history, and maintenance records, all in one place.

- 8 analog inputs
- RS-232 & RS-485 Modbus
- Remote shutoff
Big Squawk
Double the inputs for more data points or multi-boiler sites.
- 24 digital inputs
- 16 analog inputs

Monitor Your Fleet
Once deployed, every boiler reports back continuously over LTE. Track alarm states, sensor readings, and maintenance activity across your entire fleet, and shut a unit down remotely if something goes wrong.

Hold Operators Accountable
When a boiler comes back with scale damage, pull the maintenance history. Blowdown frequency, alarm events, operational data: documented evidence that the customer upheld their responsibilities.

Why we
built this
Your boilers should be earning, not sitting in your shop.
You've got millions of dollars in assets sitting on customer sites you don't control. Blowdowns are skipped, water treatments ignored, and you're left to deal with the scale damage. Every day it sits there is a day it isn't paying you back.
Squawkbox gives you tamper-proof records so you can hold customers accountable and catch trouble before it compounds.
American Made
Designed, built, and supported in the USA.
