It pays for itself in about 14 events.
How is this calculated?
You charge $50 per event as "wind monitoring with a log" (assumption: we found no published rates for this service) on 20–60 tented events a year (assumption), minus 20 min of setup, configuration, pickup and sending the PDF at $45/h ($15) per event. Saved canopies, frames and claims are not counted (no average figure with a source).

How is this calculated?
You charge $600 per installed sensor, with each tent's limits and alerts set up (assumption); it costs you the unit ($300), 1.5 h at $45 and $20 of travel (assumption). The client can buy it directly: what you charge on top is your installation and setup. Costs = what each sale costs you × sales + the licence (and any reusable kit), once. Your time is already paid at $45/h inside the costs.
Estimates with the assumptions in plain sight, not promises: your numbers depend on your business, your area and your prices. Profit before taxes, without subtracting client acquisition, payment fees, travel (unless stated), warranties, support or servers. 1,000 sales is a theoretical scale, not a forecast: it would need staff and structure not counted here.
The problem
The gust hits and your crew has no idea
In high wind, a tent puts the canvas, the frame and a lawsuit at risk: at Prairie Fest (Illinois, 2015) the settlement was $13.4 million, and in St. Louis (2012) there was a $548,000 settlement with the company that rented and set up the tent. Today the call is made from a forecast, a handheld anemometer or by eye. 10×10 tents with no manufacturer data are limited to about 20 mph, according to Yale EHS: with no sensor measuring the wind, nobody knows when you get there. A fixed wind alarm costs $561 without the sensor and gives you no app and no event log. And if there's a claim, you can't show what the wind was or when you warned anyone.
How it works
The Tent Wind Watch is a self-contained sensor that sits like a cap on top of any thin pole (a hardware-store tube, a flagpole or a ground stake), held by two cable ties, upwind of the tent, and is designed to measure average wind and gusts above the ridge for the whole event, with no outlet needed (the pole goes into the lawn or is tied to a tent leg or a fence). Every tent gets its own limit, and the app alerts within seconds, in three levels (Watch, Drop the sidewalls, Evacuate) on the phones of the manager, the crew and, if you want, the client. At teardown it produces the event wind log as a PDF: tent, site, hours, peak wind, gusts and who each alert reached. It works alongside your wind plan: each tent's limit comes from its manufacturer or your technician, and you make the call to drop the sidewalls or evacuate with the numbers in hand. Alerts travel over mobile data.
Mount the sensor on its pole, upwind, and add the tent with its limit.
During the event, the app alerts within seconds, in three levels: watch, drop the sidewalls, evacuate.
At teardown, download the event wind log as a PDF.

FAQ
What does the Tent Wind Watch cost, and are updates extra?
$190, one-off, for every use: your own, your clients' or built into your product. Updates are included with no subscription, and we let you know about every new version.
What about the hardware, and what does each sensor cost?
The licence covers the software and documentation; the sensor is bought separately, about $290 to $330 per unit. You need one for each tent you want to watch, and at purchase we tell you what to buy and where.
How soon do I get the licence?
Within 12 hours of payment you get the licence and a private download link with the software and the implementation documentation. If it doesn't arrive in time, we refund you.
What do I need on site for it to work?
Any thin pole upwind (a 5/8–1.5 in tube, flagpole or stake, driven in or tied to a leg or fence), each tent's wind limit from its manufacturer or your technician, a phone for everyone who should get the alerts, and mobile data coverage at the site.
How does it fit my wind plan, and who decides when to evacuate?
It's an alert and a record that works alongside your wind plan: it warns you within seconds in three levels (watch, drop the sidewalls, evacuate) and logs the event's wind as a PDF. Each tent's limit comes from its manufacturer or your technician, and you make the call with the numbers in hand.
Who sets it up for me?
You can do it yourself with the step-by-step guide: mount the sensor, add each tent with its limit and add the phones that get the alerts. If you'd rather not, we build, install and maintain it for you, remotely anywhere or on site depending on your area, quoted separately.
What support is included?
Written support by email for the mounting, the setup of each tent and the alerts, plus a phone call whenever you need one.
I'm an event-safety technician or tent installer: can I set it up for my clients and charge them?
Yes. You can install and use it on site for as many clients as you like and charge whatever you decide for the unit, the setup and the per-event service. What you can't do is sell or hand over the program itself: copies, downloads or the installer for someone else to install on their own. You charge for your work, not for copies of the software.
