I'm having the following problem with scenes:

1. Error message pops up in browser when I save a scene (may be due to using a previously deleted scene name)

2. Successful scene saves don't work or don't appear when Engen restarts

Here's the error code:

Code: [Select]

I've tried the following troubleshooting items:

1. Restart computer
2. Restart Engen
3. Remove and reconnect Z-stick
4. Reset Z-Stick and all devices and rebuild

Any ideas what may be happening?

I narrowed it down a bit.

The error message occurs after I do the following:

1. Build/save a scene with name (say Night)
2. Delete scene Night
3. Rebuild and try to save with same name

But in addition to that, scenes aren't always appearing when Engen restarts, in the instance where they successfully save and work.

I'm on build 36.

My system includes 3 Aeon power outlets, an Aeon LED bulb, and the Fibaro LED strip.

Somehow it all works now. Not sure what changed.

I did carefully set the scene within the settings page. Previously I was trying to save a configuration set prior to going to the settings scenes page. Maybe this was the difference.

Ok, I woke up with a clear head and figured out why the earlier error occurs.

When you press [+ New Scene] it opens a page with values displayed for each device. These values are their current On/Off and color status. However, Engen only saves the device values for the scene that you input from this point on. If you don't change anything, the website sends a POST command with no value and gets an error.

Say a light switch is on and you want to make a scene. You need to open [+ New Scene], name the scene, turn off the light, turn it back on, then hit save. Then the scene saves correctly and works.

Thanks for reporting that.  We'll see if we can make it easier and clearer.
