These have to be the least accurate things I have ever seen.

The rectangular one is accurate or accurate enough and has been what I used but I noticed files all had cutouts for these round hygrometers…

Well from my 6 pack 1 is within a margin of error to even be useful.

I get they aren’t expensive but seems like a waste of money for this bad.

    @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.

      I’d really love to know how, once having purchased and aquired these two parts, how to join them, and get them powered, and to display. this is like secret engineering knowledge i’d love to be walked through

        @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 :)
