As Event Engine becomes more popular, I see a lot of 'how can I do this' type of questions coming. So wanted to setup a spot to post your favorite Cogs!

I think everyone will know how to turn a device on or off so lets see some of the more complex stuff!

Remember, at a the bottom of each Cog is an easy to read description containing all of the Cog's options needed to reproduce.

I had lighting effects for some front lights to change colors for Christmas. Since I hadn’t used it since last year ( or maybe the year before ) I deleted it as event engine took its place. How do I have event engine random slow flash / rotate through colors like my old Lighting Effects did.

bptworld · December 11, 2021, 12:47am

It can't, Lighting Effects still works fine - I'm just not working on it anymore.

ourmessages · December 11, 2021, 12:49am

Ok thanks, I’ll reinstall lighting effects. I mistakenly thought it got rolled into EE.

phrankc · December 27, 2021, 5:15pm

WOW! EE looks extremely powerful. Sorry to bother you. It looks like they keep you awfully busy on multiple topics. I looked through the examples, but I’m not entirely clear on the overall concept, and I am surprised there is not much more activity on this example page.

Is each cog built, then several cogs are packaged into an engine?

Back in the Smartthings days, there was and old Webcore piston named “Bathroom Control”, that no longer works for me. I would like to reconstruct the logic for use in Hubitat. In that case, would a cog be built for the lights, and one for the fan, and another for the flags and variables, and those cogs are assembled into an engine?

Thank you.

Hi, Event Engine is simply a alternative to Rule Machine (or Webcore).

This is my Bathroom Cogs..

phrankc · December 27, 2021, 11:33pm

Thanks. I will try these out.
Just to clarify, the Fan cog description says "Off by Occupancy Cog". Is that accomplished by the Additional switches to Turn Off in the occupancy cog?

bptworld · December 28, 2021, 12:44am

yes
