How to save light state, then restore it after an action?

Third party integrations Node-RED
1

I have the following flow setup for my garage doors.

When the door opens, it grabs the state and attributes of my WLED lights, then changes them to blinking red.

I’d like it so when the garage door closes, it returns the effect to what it was previously, but this is not working.

I feel I’m about 90% there, but I need help getting that last 10%.

Any thoughts on what I’m doing wrong?

I do this exact thing, just with a different trigger and WAY more actions in between :slight_smile:

Here’s the code. Make sure you click into the README comment for tiny instructions. This also assumes you are using MQTT for WLED, since that’s the only way to set all the attributes at once:

edit: You will probably also want some sort of delay in between your actions and the Set payload function, otherwise everything might just flash quickly.

I would use create scene service with scene called something like door_opened or whatever and then after closing door apply this scene

4

Problem with this is that my WLEDs could be on any effect, and not a static one like a scene would be configured for

5

This looks promising! I’ll try this one out

After a lot of trial and error, I was able to get it working with the below config:

Actually found a bug that if the light was off, this wouldn’t complete because of an API error. After some more testing, this seems to be working well:

Hope this helps someone else in the future!

I’m new to HA. Just a question: how did you create these state machine graphical views? Thanks!

9

There’s an addon you can install called Node-RED that uses this visual/flow programming style for automations. It is a full separate app from Home Assistant and can do a lot more stuff, but the HA integration is really good.

thanks a lot!
