Unnamed command 12 in Chuango DWC-102 door sensor

[LuccoJ]

I don't know if one report is enough to act on this, but unlike my previous Chuango door/window sensors (which likely had another model number but I cannot retrieve it), this DWC-102 additionally generates a cmd_id=12 signal, which gets transcribed as "?", but I can confirm that in the case of my sensor, it represents the door/windows being closed, something that the previous models didn't detect (in fact, my alarm system does nothing with it, but I presume newer Chuango systems use it to warn people they've left the door/window open when they arm the alarm, like other brands do).

So, to be clear, what I get what I open and close three times my door, with its sensor set to home mode, I get

Some notes:

• Even if I change the sensor to normal (not home) mode, the cmd for closing still appears to be cmd_id=12.
• While multiple repetitions of the command are typical of these sensors, it would appear that the exact number of repetitions depends on how quickly I open or, especially, close the door, with it being closed very quickly sometimes resulting in no command being sent.
• Sometimes, the last cmd_id=12 is followed by "Smoke-GS558", "id" : [redacted], "unit" : 2, "learn" : 0, "code" : "3f1882"} which I do not believe to be a real sensor (certainly not mine, although I can't exclude a neighbor, but I've never seen it before making this test)
• Personally I would interpret these as quirks of this sensor, rather than an indication that it's not reporting "closing" but something else.

I would in fact propose "Closing" as the name for cmd_id=12, unless you want more confirmations that this is the case with other Chuango sensors.

Thanks for the report, the addition sounds good.

Thanks. As expected,

{u'model': u'Chuango-Security', u'cmd': u'Closing', u'id': 266639, u'cmd_id': 12, u'time': u'2023-09-20 19:02:06'}

(slightly different format merely because it's parsed from Python)
