FYI, got working Radar Sensor ZY-M100-S/L (_TZE204_sxm7l9xa)
As the differences were related to Tuya data points received, it’s created as new driver - not sure if Johan will keep it like this or not, I’m not expert at all. Anyway, in case you are interested in testing, you can CLI install this repo - GitHub - shaarkys/com.tuya.zigbee or cherry pick what is relevant for you.
(beware, this one contains also updated homey-zigbeedriver and zigbee-clusters Node.JS modules, with some minor modifications for readAttributes (seems to be working for me fine on several plugs) , so other things might get broken - in that case, simply install Test version from store)
Also fixed battery level measurement for _TZ3210_eymunffl / Smart Garden Irrigation Controller - but you must pair the device newly again.
One more thing related to the radar motion sensor, seems it can be used even for person detection, while sleeping, based on : Add support for Tuya MMW sensors: `_TZE204_qasjif9e`, `_TZE204_sxm7l9xa`, `_TZE204_e5m9c5hl` by pgroene · Pull Request #2525 · zigpy/zha-device-handlers · GitHub
Instructions
Firmware gives 2 functional states depending on the number of seconds set for fading time (second bar on the sensor controls) that you have set.
Fading time BELOW 65 seconds and the unit only detects large / faster motion, ignoring micro motions. As such not much use for detecting sitting, unless your a very figity person.
Fading time ABOVE 65 seconds and it detects micro motions in the central cone, like breathing etc. This makes it excellent for presence detection whilst sitting.
My suggested control settings are:
Detection Delay, I use '0' seconds. The Maximum I've allowed is 180 seconds or 3 minutes.
Fading time I use 65 seconds. Minimum sensor allows is 5, the max I've allowed is 180 to make it easy to set.
Max range, set in centermeteres 50-1000. Must be greater than:
Min range, set in centermeteres 0-1000, I use '0'
Sensitivity:
0 = Maximum sensitivity,
10 = Almost no detection ability.
If fading times is below 65 seconds I use 0-3 sensitivity. If fading time is 65 seconds or above I use 4-6 Sensitivity.
(note the Johan’s app accept settings in meters!!)
