I was trying to revive an emonTH V1.4 that I bought in Sept 2014. I was having an issue with the device not starting unless I connected the programmer. I thought this would be solved by reprogramming the Arduino, so I did it with version 1.6 found here (file emonTH_DHT22_DS18B20.ino)
Now the log on the serial says “Unable to find DHT22 Sensor” and shuts down. Which is weird because it was working before. Anybody able to help?
One thing I found difficult is to find the libraries that the firmware depends on so I’m not totally sure I did the compilation right. Thanks!
