Hi Harry, looking at the sequence log I can see the sequence has been triggering, so the IFTTT applet to trigger the sequence is working fine.
I can also see that it's fired the two IFTTT calls for your lights, and looking in the logs IFTTT returned 'success' every time. However, IFTTT will return 'success' even if it doesn't find a matching applet to trigger - basically it just confirms that SEQUEmatic sent a request which was technically valid.
Can you have a look at your IFTTT activity log to see if either of the light on events have triggered? Also double check that the event name you have provided in the SEQUEmatic steps exactly match the names you used to set up your IFTTT applets.
Let me know what you find in the IFTTT activity log then I can investigate further.
