Boot Raspberry Pi OS once logged in you can install relayct using the following command.
curl -s https://raw.githubusercontent.com/ReinierNel/relayctl/main/setup.sh | sudo bashThis start an interactive wizard, follow the prompts to install relayctl
Uninstall
Update rc.local
Remove the following entrys from rc.local
/etc/relayctl/relayctl.sh test
/etc/relayctl/scheduler.sh &
/etc/relayctl/external.sh &Delete relayctl folder
delete the relayctl folder in /etc
sudo -rf /etc/relayctUninstall Nginx, fcgiwrap and jq
If you enabled the API during the install process you will need uninstall the following packages
- nginx
- fcgiwrap
- jq
run the folloing command to do so
sudo apt remove -y nginx fcgiwrap jqDelete the cgi api script
Finaly you will need to delete the CGI api script
rm -f /usr/lib/cgi-bin/api.cgiMore

Questions
What parts does the Relayctl hat use?
44 parts, built around the BC548. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Relayctl hat KiCad files?
From the ReinierNel/relayctl repository on GitHub, at the commit this page was made from: the board is hat/relayctl-hat/relayctl-hat.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Relayctl hat design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
