Hi, welcome to the community.
I am afraid there hasn't been any updated news about Deco M9 Plus zigbee compatibility with Mija Xiaomi sensors.
In the short term, there is no plan to test Deco M9 plus compatibility with more Zigbee devices so the compatible list has not been updated for quite a while.
But if you have confirmed any compatible devices, it is highly appreciated if you could share them with us:
Zigbee Compatibility of Deco M9 plus
Thank you very much.
Best regards.
