In the truck
A small ESP32 board with an LTE modem watches a dash switch. Flip it and the board sends one tiny message over cellular. An LED confirms it landed.
In the cloud
The site's API stores the status and location. GPS on the board means the pin follows the truck automatically — no typing addresses.
On the site
Visitors' maps flip from gray to color within a minute. A phone-friendly console remains as backup for naming the spot ("here until 1pm!").
Online orders
The bean shop replaces the Squarespace store. Stripe handles payment, tax, and receipts; orders land in a phone app. No monthly platform fee.
One calendar
Public events show on the site; private bookings block dates without leaking details. Webform requests land in the truck console — with room to sync to MFIS Group's calendar system.
