What does a GPU box cost for 9 cameras? We looked at it for trailers and it got expensive fast.
Total newbie question: why not just LoRa on each node and skip the cable?

Pourriez-vous en faire un interrupteur qui écrit une valeur de télémesure, et faire surveiller cette valeur par l’ESP32 ? C’est ce que j’ai fait pour une lumière.
Could you make it a switch that writes a telemetry value and have the ESP32 watch for that? That’s what I did for a light.
Could you just connect to the broker’s IP address instead? Then DNS doesn’t matter.
ok not the chips then, good to know
Cheap clone chips? We had a batch of clone transceivers that were all bad.
Total beginner question, but why not put the Nano’s job on the ESP32 and update that one over Wi-Fi?
Changed to a complementary filter on the ESP32 and a message every 10 s with tilt_max, no more drops or closed sessions. Tipped the test pallet by hand in the warehouse: tilt_max 78 and the alarm fired within the same second. Dropped yaw like ciaranwalsh55 said, it was jumping around in the trailer.
Following, I have the same board coming next week.
The downtime number is what would’ve convinced me too. Fair.
Did you try swapping A and B?
Dumb question maybe, but why not read the value from the PLC over the network?
Founder here (not Eric’s!). Honestly I’d have the same instinct. What’s the real argument beyond « PLCs are the industry standard »?
You could split it on the dots and atoi each part, then IPAddress(a, b, c, d). That’s what I did once.

cmd n’est-il pas un code défini par la puce, comme « démarrer la conversion » ?
Isn’t cmd a code the chip defines, like « start conversion »?
