How much does it cost to build an OCR water meter?
Hardware is easy, but reliability for 10 years is the real challenge. ESP32-CAM based & NB-IoT solution retrofits analogue meters using Edge AI.

Avoiding vendor lock-in means owning your IP. If your dev partner refuses to share source code or overcharges for modifications, you're stuck.
Choosing a partner that transfers full rights to code, PCB schematics means You keep total control.

Testing in embedded systems isn't a luxury - it's a must. Manual testing creates bottlenecks and inconsistency.
Automated integration testing ensures sensors and PCBs work in symphony, speeding up time-to-market and reducing returns.

Building an IoT system? Don't let energy & topology be your bottleneck.
While Wi-Fi drains batteries, Thread lasts years and offers a self-healing mesh. With Matter, you can finally use both: Thread for resilience and Wi-Fi for bandwidth.
