Lambda/rule to flash lights for a period of time?

[higgers (Steve Higton)]

Does anyone have a lambda (or any other solutions) that flashes some lights for a set period of time? I have a homebrew zwave doorbell that sends me a Telegram message when it’s pressed and I’d like to enhance that rule to flash lights around the house as well so I can still be notified that someone is at the door when I’ve got loud music playing. Various rooms in the house have a combination of Zwave and Hue lights and I’d like to be able to control the doorbell light notification function via a switch. This would enable the light notification functionality to be turned off if someone is sleeping, etc.

I’m interested in any similar solutions anyone has implemented.

I just wrote up an approach that would flash lights using morse code.

Loop rule (in OH2)

That is because you didn’t use code fencing, you used quotes. ``` code goes here ``` One thing I will note is that any sleep of more than a few hundred milliseconds can cause problems in the long run because it ties up a Rule execution thread. This Thread ties up an execution thread for 11 seconds at a minimum, potentially and likely longer. If you have sleeps in other rules that are executing at this same time you can bring your OH to a halt as it runs out of Rule execution threads. Given th…

This should give you a good start.

I will note that not all wireless technologies will be able to support rapid flashing of the lights like this.

To override the flashing just have a Switch and check to see if it is ON before calling the lambda in the doorbell rule.
