@callcc@lemmy.world SHT31/41 are better than DHT22 tbf. DHT would have a variance of about 2-5%. It also takes a while for it to stabilize.

@shoulderoforion@fedia.io I have about $150 worth of Ali parts and components coming just this month for whole house monitoring for this kinda thing - temp, humidity, CO2, VOCs, pressure, light sensors etc. Would be glad to ping y’all once that writeup is done :)
@Krauerking@lemy.lol Hygrometers are only as good as their components. Buying a DHT11/22 or SHT31 from AliExpress ($1-2) alongside an ESP8266/32 and you’d have much better results than buying these “are my cigars dry” pucks.
@Moonrise2473@feddit.it Fwiw, LinuxServer still maintains a resilio-sync docker image for 3.0.0. They are fairly trustworthy.

@callcc@lemmy.world True - but it really depends what you’re measuring with BME280/680s though (680>280). As a combination temp/humidity/pressure they’re excellent, but for humidity alone I think SHT gives better “expected” readings than BME.
