Hospital Bed - Raspberry Pi Forums
hello, i'm quadriplegic , best friend siri , use siriproxy
control devices have.
have electric bed has functions head up/down, foot up/down , raise/lower.
wired controller has 6 buttons , plugged in using 10p10c rj-50. uses 7 pins 2-8. fooled around them through rj-50 break out board , found pin 2 must ground because when pins 3-8 connect pin 2 perform function.
using siriproxy control gpio's i,m doing.i need on wiring please.
should use transistors, relay's or need @ put pin2 ground , pins 3-8 gpio.
in advance input.

it depends on how current connections take. i'd assume not lot push buttons. in case i'd go simple opto-isolators keep pi electronics separate bed electronics.
connecting other pins pin 2 makes bed function. doesn't mean ground (unless tested meter). +5v or +3.3v or low voltage. you'll need check polarity first. don't see real problems getting working.
circuit crude ascii art each pin.
