@György-Farkas is correct, DHT11/22 sensors are not 1-wire sensors, that hadn't clicked with me.

Check out this blog post on reading DHT11/22 sensors with the Omega2: https://onion.io/2bt-reading-dht-sensor-data/

@James-Harding i'd guess the mjpg_streamer is using most of available current, causing dht sensor to error state and would increase available current for dht sensor or pin20 also used by mjpg_streamer.

Hi all
Good news. I migrated original code successfully to work on Omega2!
See https://github.com/h0l0gram/omega2-checkHumidity for binary and source.

Make sure your Omega2 has firmware >=0.1.10 b160 or it won't work.

Sounds interesting, but what makes this platform any better than the major competitors, Brillo/Weave, IOT Eclipse, Apple HomeKit, etc, which have nearly unlimited resources and a reputation. I understand that you have built something for the onion, but it wouldnt be that difficult to duplicate for another platform.
