Hi, i have a Siemens LOGO 8 which i communicate with (S7 protocol) via Node Red and Blynk. There is no code, just Node Red handling things.
The LOGO is used to control the automatic cleaning (flushing) of the drumfilter for my Koi pond, one of the (multiple) other things it also controls is e.g. a simple on/off button for the pump.
For now i use the following flow for buttons
It reads the button status from blynk datastream, when stream is 1 (button on) it sends a True command to a network switch in the LOGO and the pump is switched on.
The second half i use now as live feedback from it’s status in the LOGO back to Blynk.
But… is the second half of the flow necessary or right? and how to do it otherwise?
