+
+Wiring: V to VIN (5 V, the module wants 3.6 to 5 V), G to GND, sensor TX to GPIO16 (RX2), sensor RX to GPIO17
+(TX2), IO2 to GPIO18 (presence output, a gpio binary sensor), I1 unconnected. `templates/dfrobot-sen0395-dut.yaml`
+has the hub, both detection binary sensors, the four switches, settings buttons and junk-line buttons.
+`scripts/dfrobot_sen0395/ctl.py HOST KEY press:NAME sw:NAME=on|off wait:S` drives it and prints binary sensor and
+switch updates; `cases.sh DEV_IP KEY CAPTURE LABEL` runs the whole flow against a running serial capture. Flash by
+USB, `serial_capture.py PORT 540 CAPTURE --reset`, then the cases; compare the `Sending command` and `Message:` lines
+and the counts of `Done`, `Error`, prompts and frames between builds. The module echoes every command, so the echoed
+lines are the bytes the component sent and can be compared between builds as a set.
+
+Module facts: it answers `Done` or `Error` and then the `leapMMW:/>` prompt without a line end; a junk line gets
+`<line> is not recognized as a CLI command` (36 chars longer than the line, so 220 and 240 byte junk gives 256 and
+276 char replies); input lines of 256 bytes or more make the module assert (`..\User_code\main.c line:232`) and
+restart, after which the sensor is stopped; a factory reset restarts the module about 7 s later; `sensorStop` on a
+stopped sensor answers `sensor stopped already` then `Error`; a settings press takes 5 to 6 s (stop, change, save,
+start). Free heap on the ESP32 is Wi-Fi noise (192 to 198 kB) and says nothing about the component.

+## Held report versus a later call (#21144)
+
+A report that arrives during a transition is held and applied when the transition ends, unless a call came after
+it. `scripts/homeassistant_light/heldcase.py DEV_IP KEY BULB_IP same|many [BULB_KEY]` (a key of `-` is plaintext) keeps one API connection to the mirror
+device and one to the bulb so the steps land inside a 3 s fade: press "A 50 fade 3s", 0.7 s later set the bulb to
+90% directly (the report is held), 1.4 s in press the same fade again (or "A many calls", 16 calls in one loop
+pass). Pass: the mirror and the bulb end at the second call's target. Only `same` reproduces the bug: a build
+without the fix logs `Applying the report that arrived during the transition` and the bulb stays at 90%. `many`
+ends at 100% on both builds because the last call's target differs from the held report, so it is a regression
+check only, not a reproduction. Separate button presses are too slow (about 1.5 s each) to land inside the fade.
+The mirrors are not API entities, so read their state from the "Log state" button's line. Results: https://github.com/esphome/esphome/pull/21144#issuecomment-6278257695

 To make a target "leave" without anyone moving, set the radar's Zone-1 numbers over the target and
 switch the zone type to `Filter` (the count drops to 0 within 0.5 s); set it back to `Disabled` after.
 Writing those numbers blocks the ld2450 loop about 50 ms.
+
+## Zone numbers round trip (#21146)
+
+`scripts/ld2450/zonedrive.py HOST KEY(- for plaintext) set:NAME=VALUE sel:NAME=OPTION wait:S list` sets numbers and
+selects over the API and prints every LD2450 state update. After each set the hub sends the set zone command, queries
+the radar and republishes all twelve coordinates from the answer, so set each coordinate of each zone to a distinct
+value and check the readbacks; no target is needed. Readbacks can arrive late over Wi-Fi, so match them by content.
