Reading “do we have IoT” as “does the wall have a curve” undersells it. The real difference: at 2 a.m. heat rise, can the system hand the job to the person on shift—or leave a red lamp for the first person into the duty room.
The path breaks at every node that must “forward a fact.” Safety arrives and can only search a chat.
People on the decision chain need not stare together. The exception still moves.
Note: a camera wall that only shows pictures, or a box with no API, is close to “not hooked up.” See Cameras without work orders are not software and Devices are online. Why the floor still stares at screens. After hookup, an alert can still die if nobody claims. Turn the pop-up into assignable work: Fewer screens to watch and After exceptions open tickets, missed handling drops.
Monday day shift opens a door to cool; temperature spikes. The unhooked system fires twenty times; night mutes notify. Tuesday a real overheat, nobody cares. A hooked system merges spikes, silences a maintain window, opens one ticket on the real overheat, and knows who closed the last one and which part changed. The gap is not sensor brand. It is whether the event entered the maintenance and production system you already use.
Night shift tests both paths. Unhooked, mute is the only tool; days face a pile of stale reds and ignore them all. Hooked, maintain window, hysteresis and merge live in the system; a real overheat still opens a ticket and escalates to the lead. Closed access locks you on the left path: Closed box vs. open access. DaXi Technology does hardware-software by asking who handles the exception, then which device to join. To move the left path to the right, start at Hardware-Software Integration.
If after hookup the crew still lives in WeChat, the path gap will not appear. In the pre-shift meeting look at open tickets and timeouts. Tool into habit, and the contrast becomes less downtime—not a diagram.
Unhooked, companies add people to stare. Hooked, you can cut a watch post later—not fire first and install later. Write “an exception must point to a ticket number” into acceptance so the project does not stop at pretty red lamps.
After overtemp, a missed check or a missed punch: pop-up or ticket. Send the as-is; we will design access as a loop.
