Back again after a couple of weeks… I’ve got a bit of a peculiar setup with 2 Raspberry PIs and an Arduino Duo.
- PI (One) is essentially my emonPI - it is coupled up to an Arduino Uno running emonLibCM (Thanks for the “Heads Up” @Robert.Wall) by USB cable. The Arduino is fed by a CT sensor, AC current sensing, pulse counting and temperature. I have Arduino IDE installed on this PI so I can remote access via VNC Viewer to allow “tinkering”.
- PI (Two) is my EmonCMS (built from the emonPI SD card image)
I’m considering merging the PI hardware, running a single PI with the emonPI/CMS SD image. The Arduino would be linked with the single PI by USB cable to provide both power and the serial link.
My only concern is that I’ll still want to tinker. I don’t think I’ll be able to install VNC Viewer and Arduino IDE on the PI as well, or is there a solution to do so?
In order to tinker, I’d then need to take laptop into the garage and directly couple up with the USB link. I’d prefer not to but there is a balance to be had with how often I’d be tinkering.
BTW, I’ve got ESP8266 cards due to arrive in the week - another potential upgrade to my project…
Thanks in Advance
