Hi Jeff, yes, you should be able to achieve this with SEQUEmatic. An overview of the sequence you'd need to create would be:
- A trigger of some sort - time based, or you could use the IFTTT webhook to link it to any of IFTTT's triggers
- IFTTT webhook call to change the light to red
- Pause for 1 minute
- IFTTT webhook call to change the light to yellow
- Pause for 55 seconds
- IFTTT webhook call to change the light to green
- Pause for 5 seconds
- IFTTT webhook call to reset light colours
