Has anyone tried to use multiple DTH22s on a single EmonTH?
I have two rooms where I would like to monitor humidity, but I would like to use only one EmonTH (Could be a little money saved)
Best regards

Re: EmonTH with multiple DTH22
I think it might be possible, but not easy. The humidity sensor has an analogue output, and the emonTH was designed to use only one of these. Although there are analogue inputs free, they are not accessible unless you solder on to the i.c. pads. You can get the schematic and pcb layout drawings via the Wiki.
