Since my clock lives on my desk at home and I'm only there between certain hours of the day, I figured it would be great if I could easily trigger my Pixel clock to turn off during my away (sleeping) hours. This is a very simple n8n workflow that can be customized for your needs, and expanded, if say, you keep your clock at work and you're not at the office on Saturdays and Sundays.
This is probably the simplest n8n workflow to set up, and is a great place for beginners to start their pixel clock and n8n workflow journey.
Setup
Step 1: Changing the Clock IP Address
Under each node for "Clock On" and "Clock Off" you'll need to ensure the the clock IP address is correct under the URL field.
Step 2: Changing the trigger times
This is as easy as going into each Trigger Node (Night Trigger & Day Trigger) and adjusting their run times.
Customization
You can duplicate any of the triggers and HTTP Request nodes to create your own on/off triggers. Since these run independently, you don't need to create extra workflows, just add any other trigger days/times into their own separate trigger sequences and let the magic happen.
