Let's Control It

Hi.
What the simplest way to blink diode with 100ms rate continuously?
I need it show alarm status.
I try 2 rules with timers and "pulse,12,1,100 pulse,12,0,100 ", but it too complicated.

Maybe create a new command for that: "blink on 12 gpio with 100ms rate"?
Or add this to Notifications with adjustable settings?

Sub second is not a job for the rules engine which is called once/twice per second. So for that a plugin would be needed. You could request that on GitHub.

Hi why don't take a blink-LED?
Noting easer than this.
100ms? I find this very fast.
