Hi, I have problem with OnOff Shim my /etc/cleanshutd.conf is: # config for cleanshutd (commented out values are the defaults) daemon\_active=1 trigger\_pin=4 led\_pin=off poweroff\_pin=4 hold\_time=1 shutdown\_delay=0 polling\_rate=1 By pressing the push-button on the Shim, I am able to turn on my RPi3B+ I am unable to turn the power off by pressing the same button I check the signals with oscilloscope and it looks like when doing the OFF press, the level on pin BCM17 goes low and the level on pin BCM4 stays high. It looks like the software is running root@RPi3AP:~# service cleanshutd status ● cleanshutd.service - LSB: Monitoring GPIO shutdown trigger Loaded: loaded (/etc/init.d/cleanshutd; generated; vendor preset: enabled) Active: active (running) since Thu 2019-03-07 22:32:45 GMT; 32min ago Docs: man:systemd-sysv-generator(8) Process: 303 ExecStart=/etc/init.d/cleanshutd start (code=exited, status=0/SUC CGroup: /system.slice/cleanshutd.service ├─ 391 /bin/bash /usr/bin/cleanshutd └─4308 sleep 1 Mar 07 22:32:44 RPi3AP systemd[1]: Starting LSB: Monitoring GPIO shutdown trigge Mar 07 22:32:45 RPi3AP cleanshutd[303]: Starting… Mar 07 22:32:45 RPi3AP systemd[1]: Started LSB: Monitoring GPIO shutdown trigger Following the hint from here [Onoff Shim not restart](https://forums.pimoroni.com/t/onoff-shim-not-restart/7345/5) when I execute root@RPi3AP:~# sudo /lib/systemd/system-shutdown/gpio-poweroff poweroff the response is: Reading config file /etc/cleanshutd.conf Using power off pin and the system is powered down. Question: How to fix it? ---

additional info: if I run: root@RPi3AP:~# /usr/bin/./cleanshutd I have Unknown GPIO “off” monitoring BCM 4 If anyone has the latest version of hardware and software, can you tell me the working contents of /etc/cleanshutd.conf ---

fixed, it should be: # config for cleanshutd (commented out values are the defaults) daemon\_active=1 trigger\_pin=17 led\_pin=17 poweroff\_pin=4 hold\_time=1 shutdown\_delay=0 polling\_rate=1 ---

I was mislead by a github [https://github.com/pimoroni/clean-shutdown/blob/master/daemon/etc/cleanshutd.conf](https://github.com/pimoroni/clean-shutdown/blob/master/daemon/etc/cleanshutd.conf) Can someone responsible fix it? ---

Ah- interesting spot. BCM 4 is the default pin for Zero LiPo, whereas OnOff SHIM uses BCM 17. Furthermore the installer wont uncomment - or possibly even properly change - config lines when setting up for a specific breakout. My bad- I merged a PR that changed the script and config file without thoroughly testing it. I’ll raise an issue for this to be fixed ASAP. Edit: Raised, track here: [https://github.com/pimoroni/clean-shutdown/issues/21](https://github.com/pimoroni/clean-shutdown/issues/21)
