Pulls system info, bus stats, MQTT state, live values, top 20 changed registers, BLE state, and the last ~80 events into one JSON blob — paste into chat for me to debug.

Locked toauto

Pick access point

On a mesh network (Vodafone Pro, Deco, Eero…) the ESP32 can latch onto a far AP and not re-evaluate. Auto-roam runs every 5 min when the current AP is below -75 dBm; Roam now evaluates immediately. Scan shows the list to manually lock to a specific BSSID.

Chip-temp baseline —

The on-die sensor reads ±20 °C high on some ESP32-PICO-D4 dies — the absolute number isn't useful, but a delta from a known idle baseline is. Run capture once after install; re-run if the room ambient changes a lot.
