How?

If it do not work, in Traces it shows just nothing.

If I deactivate the delay and use the "start action" switch, my switch turn on. If I reactivate the delay, then save, click the "start action" button, the action works for one time. At the second test nothing happen!

And if I use a short delay about 10 sec. everything works fine too.

Since I activated that action it never worked. So it is not just a bug in the "manual start of actions"
