Hi,  
at moment I write nodes for realize control and automation projects with node-red.  
I publish this nodes next time.  
This nodes access the io hardware.  
For example on Raspberry Pi using the gpio.  
On market they are lot of modules and hats for industrial IO.  
I use for examples Unipi1.1 io module.  
Can you give here recommendation and links for other modules and hats ?  
The modules/hats can have digital inputs/outputs, relays, analog inputs/outputs ...  
I can write then the nodes for this modules.

Thanks a lot
