This software is a data collecting tool, written in python for Temperature data logger RC-4/RC-5 and Temperature and Humidity data logger RC-4HC.
Elitech RC-4 / RC-4HC / RC-5 is a reasonable data logger.
RC-5+(Note the plus "+" sign). is not supperted.
Enables to use RC-4/RC-5 on Mac, Linux, Windows.
This is an unofficial tool. This tool was made by monitoring and guessing serial communication data. That is why this software is not perfect.

Elitech device gets the data in units called "Page size". Page size is determined by the device model. RC4 is 100 and RC5 is 500.
You can directly specify the page size, with an optional argument --page_size. (for debug)
$ elitech-datareader --command get --page_size=500 /dev/tty.SLAB_USBtoUART
