- Fri Oct 09, 2015 2:47 pm #30969 now that the detectoon works stable, is the sht just not working in company or even making problems as only sensor in the system?

- Fri Oct 09, 2015 3:32 pm #30973 There are 3 sensors. The pressure sensor is fairly reliable. The IAQ sensor works occasionally but the SHT has never worked. I have an SHT on a breakout that works on an Arduino uno but not on a huzzah - same symptoms as my board.

I upload test code and a library for each sensor individually so there shouldn't be any competition. I'm using the same code to test the SHT breakout on both the Uno and Huzzah (esp8266).

- Fri Oct 09, 2015 6:09 pm #30982 as I don't know which lib you are using but two out of three (the one from sparkfun seems to use nohold mode) that I found use "hold" mode, it won't work on the ESP8266 since i2c lib hasn't implemented clock stretching ... so maybe it is just the wrong lib for esp8266

- Sat Oct 10, 2015 11:27 am #31038 Schufti, you're a good man No hold master mode + 100KHz seems to be the magic recipe. It wasn't working last night but all 3 sensors started talking when I powered it up this morning - go figure.

Thanks for your help!
