Hello All, So we have a great selection of sensors for the TH10 & 16 but what are the main differences? I understand that AM2301 (temperature & humidity) , DS18B20 (temperature) & si7021 (temperature & humidity). But what are the main differences between AM2301 & si7021? Thanks in advance, MOA.

I remember reading somewhere that the Si7021 was more accurate although I can't find where I read that and there was nothing to back it up.

You can read here that the Si7021 is highly recommend. https://www.itead.cc/sonoff-th.html https://www.sonoff.in/index.php?route=product/product&product_id=59 But the description was more clear where they strongly recommend one option because that was more precise.

Recent purchases of Si7021 is having problem of loosing temperature reading for 2 secs causing TH switches for same time troubling connected load. Many people reported similar problem in the forum. May verify before purchase.
