I manage maintenance at a cold storage…
I manage maintenance at a cold storage warehouse in the Netherlands. We run about 40 cooling units across two sites, and keeping temperature logs was a nightmare. Staff walked around with clipboards every few hours, wrote down readings, filed the paperwork. If a unit failed overnight, we found out in the morning when the produce was already spoiled.
We brought in Iotellect to connect all the temperature sensors and compressor controllers. Most of the hardware was older Modbus stuff - the kind vendors tell you to replace. Iotellect talked to it fine. No rip-and-replace, no new wiring.
Now I have a single dashboard showing every unit in real time. If a temperature creeps above threshold, I get a notification on my phone immediately. No more clipboard rounds. No more ruined product discovered at 7 AM.
The low-code part was a pleasant surprise. I am not a programmer, but I built the monitoring screens myself over a couple of quiet shifts. Dragged in widgets, set alert rules, done. Support jumped in once when I messed up a register mapping - quick call, fixed in ten minutes.
The interface throws a lot of options at you, and early on I clicked into menus I still cannot explain. It works, but it could be tidier. Also, the documentation assumes you already know a few things about IoT architecture. If you are new to this, expect a learning curve.
Overall, it solved the problem we actually had - not the one a sales deck imagined. Our spoilage rate dropped, our audits are smoother.
