Hi i have openhab2 on my raspberry pi 3 and i’d like to read out the state of gpio pin 29 (just if on or off)
the gpio is connected to a voltage divider, which can set the pin to high or low
and if i type in the console “gpio read 29” everything is perfect, if the pin is high it says 1 and the other way round
i have a Contact in my items file set up
Contact pcstatus “Der Computer ist [%s]” { gpio=“pin:29 force:yes” debounce:10 }
(of course correctly set up in the sitemap)
the problem is that it does always say open even if the pin changes from high to low
i do also switch some gpio pins (as output) but with the rules set up as the following one
rule "deskpowerON"
when
Item deskpower changed to ON
then
executeCommandLine(“gpio -g write 6 0”)
end
so is it possible to let openhab read out the pin (with “gpio read 29”) and set the pin into a variable, with 1 as open and 0 as closed?
