I have been looking through the wireless sensors and receivers but am a bit confused as to what I would need to get started. What is the difference between these modems?
If i setup a pi Zero with a 4 channel 4-20ma input I2C board can one of these devices transmit data back and forth to a receiver if no internet connection is available? I typically use Node Red to read the input cards.
I am working on extending our current project into remote areas where we have no network access. All locations have power just no way of line of sight transmission in some cases.
I am also considering deploying some of these 4-20ma input Industrial IoT Wireless current receivers. Are they only compatible with the industrial line of Modems?
