I have a bunch of demo scripts for my SSD1330 SPI based Colour OLED Display. It seems the only way to control this display is via Python scripts. Fine, I can do that But I wanted to try controlling it via Node-Red.
I found the daemon node, and it works just fine as is (repeatedly runs my script) but the directions are unclear as to how to control the node more precisely.
Setting msg.kill to a signal name (e.g. SIGINT, SIGHUP) will stop the process - but if the restart flag is set it will then auto restart.
Sending msg.start will also re-start the process.
After unchecking the auto-start/relaunch flags, I have tried setting up to inject nodes to send msg.start and msg.kill... but nothing seems to work, it just throws this clear error Command not running... doh, I can see that
