That is the graph of smoking in the next room balcony, where the balcony door is open and i smoke 2-3 cigarettes. It might be a little sensitive i don’t know, especially the clearing of smoke values (I didn’t opened a windows in that sensor room) … Btw there was only a little smoke smell in that sensor room,no smoke itself. Just for your info on Xiaomi sensitivity on smoke.
UPDATE: Btw Youpin Smartmi PM 2.5 might be a cheaper alternative, although i have no idea if it works with HA…
UPDATE 2: It looks like it doesn’t have WiFi. Sorry, my bad…
