Named history log channels, as recorded in the unit's internal per-minute log
buffers (WS transport only — reverse-engineered from the unit's own web UI,
not part of the documented Modbus RTU register map).
Temperature channels (0–3) are in centikelvin, matching the live sensor
registers; the rest are raw values (ppm, %, RPM, etc.) with no conversion.
