on the lywsd02 there is an pm2.5 field that can be shown by mi gateway from conditioner (as sample). do you see any suspicious BLE endpoints that can do that?

Can you show us where you found the information that the lywsd02 clock supports pm2.5? I just found additional devices that can measure particulate matter and it wonders me as the lywsd02 isn't advertised with this feature.

I have double checked. looks like it may be a mistake( i have found info only on 1 review. https://mysku.ru/blog/aliexpress/80414.html (sorry, russian) ill look at its endpoint today...

For me the linked review and the comments are quite interesting. But I think the clock can just show the pm2.5 value measured by other devices but it means at the same time that there should be an endpoint to set this value.

@merlokk unfortunately, I don't have Xiaomi's conditioner to play with it. But you may try to do same actions as was made by me to reverse LYWSD protocol, it described in this article.
