The problem / 问题详情

the zhimi.airp.va2 "air filter pro 4" air purifier usually reports a pm2.5 value. it seems to have stopped. power cycling the air filter will update the number to whatever it's first read is, but then it never updates again. I noticed when the value hadnt changed at all in a few days. having a look at the history:

i can see that on approx 1am may 4th the integration just stopped updating and seemed to only update when home assistant was restarted.

Try reloading the integration and/or restarting the purifier. fixed it for me.

[SodaWithoutSparkles]

it seems that the integration forgets to refresh the status for the sensor. I can see that the attribute for pm2.5 in the main fan entity was updated, but not the dedicated sensor.

It seems that this issue affects xiaomi.airp.mp4 as well.

@al-one 帮忙看一下为什么净化器的代码里面，就算pm2.5的attribute更新了，也没有更新 pm2.5 实体。就是从开发者工具里面看到environment.pm2_5_density 更新了，但是sensor.xiaomi_mp4_pm25_density 还是没有更新。

[SodaWithoutSparkles]

Temporary mitigated by using a template sensor to read the attribute from the main fan entity.

state_attr('fan.purifier', 'environment.pm2_5_density')
