Marci,
I tried several times to install your software on Raspberry Pi 3 model B.
For some time, Node-Red has been installed as part of Jessie's system. Some software packages like "wiring-pi" or npm over the last year have been
altered by the authors.
For this reason, despite several attempts I have not been able to install the software.
I also tried two other Raspi models, 1 B+ and Zero.
Last year was too many subtle changes to the software components.
Can you post a working image of the software?
In my case, I need a image for the Raspi 3 B.
I have a Celestron 130 SLT with a damaged motor plate.
I will be very obliged.
