6/8 Buttons battery remote node

@carywin Certain arduinos such as the pro minis can ONLY do interrupts on pins 2 or 3 from my understanding.

IIRC, you can do interrupts from other pins too, but each is tied to a separate bank of pins, so you have to do additional testing to determine which specific pin triggered the interrupt. In the case of the voltage divider keypad, that should be no problem.

I'm planning to use some cheap RF remotes and connect a RF receiver to my RPI, which hosts both my gateway and controller.
I finally received the RF remotes and receiver/decoder from eBay and got them set up to talk directly to my controller - they work pretty well: https://youtu.be/9458-3IiG3Y
I did try a OneButton-type approach on a MySensors node, but had lots of malfunctions with long-presses (e.g. fade up 10% per second whilst the button is depressed), where the the "button pressed" message gets through, but the "button released" message is delayed or dropped.

@wes Maybe your resistors don't have a high enough power rating for the current that's running through them? i.e. holding down the button heats them up and therefore changes their resistance? That might explain the slowness to react as expected after the button is released. After release, they cool off and eventually return within their expected resistance tolerance, at which point the expected behavior finally happens.

@NeverDie do you think a NRF5x would be better solution to make a small compact remote control?
@gohan It's hard to answer a question like that in a vacuum, but in general, I do like nRF5x better than nRF24L01 beause of nRF5x's better link budget. I also like LoRa because of its great range and coverage. I have made remotes using each (and I have made posts about them), and they each have their place.
