Hello,
I can create a Labview program as a stand alone program for windows computers based on your requirements.
But I need more details, specially the commands for controlling requested elements.
So a kind of "remote manuals" or "commands manuals" to know how to read the temperature via USB, control relays board via USB and what commands to send to the USB controller.
Regarding sending text via email I think you should use Outlook to get a better functionality.
Please provide details.
Best regards,
Nicolae
