I have a question regarding node-red, before jumping on it. I find a big difficultly to get a home-automation tool such as node-red, to get working multiple raspberry pi nodes.
On the master I use django(brain)+angular(web-ui)+pigpio-library to interconnect the master pi with slaves.
Basically using pigpio I can send from the master turn-on or turn-off signals to slave without any other tool.
- In my home configuration, I have 3 raspberry pi.
- All 3 are connected to the same network.
- 1st pi is master and the other 2 are slaves.
- 2nd and 3rd raspberry pi are slaves, and only have pigpio service installed
- this give me centralized interface to n pi`s connected to my network
- downside it that our app is not yet able to do complex things:events, tasks, etc. So if I want to connect a PIR to my master and based on this trun on a LED on slave`s gpio, I cannot!
In node-red or home-assistant, both use mqqt to send or receive information regarding sensors or manipulate gpio`s.
Can I have with node-red a centralized interface installed ok master pi, and from there to act upon a gpio on slave pi?
thank you George
