the one in the github isn't working

The Raw URL I've provided above is the one from "petrd" github where the fix is still pending...

If people wish to merge it manually using diff, here is the commit :

- Thu Oct 08, 2015 10:19 am #30884 Well, I've tested this multiple ways, but I still can't get this SHT21 to work. I can upload the same code to an Uno and it works perfectly. When I reconnect the sensor to the ESP I get nothing useful :/ I've got a few extra breakouts lying around. I would be happy to send one to a guru if they want to sort this out. The pressure sensor works, as does the IAQ sensor. It's just the SHT that isn't communicating :/

It looks like it's running in hold master mode on the Uno if that makes any difference... I need a better logic analyzer :/

- Thu Oct 08, 2015 12:36 pm #30890 first it woukd be interesting if you can see the sensor with the i2c-scanner allready. For this it should not be relevant if the used library makes use of hold master mode (allthough that seems not to be supported by i2c on esp8266).
