The problem is that the device ran out of memory, not that the file was not found. He would need to compile (node.compile("dht22.lua")) the module so that it use less ram.

Indeed, seems like not all the modules are made equally.

Thanks, compiling the dht22.lua worked. Be sure to have the firmware version where the node.compile method is implemented!

It's working now, great!

Why do we need to do the calculation "((temp-(temp % 10)) / 10).."."..(temp % 10)" to get the right temperature?
Why doesn't the method dht22.getTemperature() just return the right value?
