WZ-M100-W Motion detector: Unable to set detection_delay

What happened?

Pairing with the WZ-M100-W - Wenzhi Human presence sensor works perfectly, but by default that motion sensor sends MQTT message every 500ms and totally spams the network.

According to the documentation the detection_delay can be configured to up to 10s. When using mosquitto_pub .... -t 'zigbee2mqtt/motion_human_presence_1/set' -m '{"detection_delay": 10.0}' I get the following logs:

which looks like that the 10s have been picked for a short time, but then reset back to 0.5s. Any clue what I'm doing wrong ?

What did you expect to happen?

I would expect that the detection_delay (and hence the frequency of issued mqqt events) will be set to 10s.

How to reproduce it (minimal and precise)

Just pair with WZ-M100-W - Wenzhi Human presence sensor and try to reduce the frequency of messages.
