Nexlud LED Strips for TV Backlight and Home Automation (Magic Home)

Standard

My desire to integration visual notifications into our home automation setup has remained, despite taking the color-changing LED bulb out of the setup when we moved. I recently begain toying with the same bulb and in the process I realized it might be fun, and useful, to find an LED strip that I could place behind the TV. It would add a nice atmospheric effect and also provide another source of visual indicators. I have started working on using the bulb for washing machine notifications and other events, but those notices are suppresed after 10 pm at night, and that light spends most of it’s time simply functioning as a normal lamp in the bedroom.

With any home automation setup it’s always best to ensure that a device is compatible with your controller, before purchase. Fortunately, someone had developed the FLUX LED plugin to make certain Magic Home devices available to Indigo. I decided to order a wifi and IR controlled Nexlud LED Strip Lights set, which only cost about $30.

It’s taken some work, and I had a color value conversion issue that I’ll mention in another post, but it appears to be working great. My next step is to set it to automatically turn on when the TV is powered on, and to turn it off when the TV is powered off. I’m not sure, yet, if I can accomplish this via Indigo. I test the Harmony Companion plugin, but I think it is only aware of Harmony interactions initiated within Indigo. I could be mistaken, which I’ll find out of for certain. If that doesn’t work, I’ll train the Harmony itself to interact with the device (Harmony didn’t automatically recognize this device in its database of codes).

Updated 2018/08/08: I also have it setup to be controlled via the Harmon Hub. This just required training the device to recognize the remote commands, which wasn’t difficult but did take some time to program most of the color modes. I also added control via Alexa, though now I only control the on/off state through the Hue Bridge emulation between Indigo and Alexa, instead of using the Magic Home skill.

IR Controlled SPDIF Optical Audio Switch (TNP Toslink)

Standard

I continued dealing with some audio problems after replacing the TV that our son destroyed. The audio output, when routed through the TV from different devices, often had a significant delay when playing via the soundbar. The soundbar received the audio signal over an optical cable from the TV. I tried adjusting numerous audio settings on the TV itself, as well as the connected devices, but no configuration would ensure that all devices worked without a delay (in some cases one device might be good but others experienced problems).

It’s likely that simply using the TV’s speakers would have resulted on no audio lag but that’s simply not why I have a soundbar in the first place. In order to test this problem I grabbed an old optical audio switch out of the closet and set it up with each input running into the switch. It has a single output that I connected to the soundbar. This was a manual switch, so in order to change inputs one had to turn a large dial on the device to physically change the active connection.

Sure enough, it worked without any problems. I decided to order something more modern, that could be controlled via infrared (IR) in order to allow the Harmony Companion system to handle the audio switching.

After reading through several reviews on Amazon I settled on theĀ TNP Toslink SPDIF Digital Optical Audio Switch with Remote Control and ordered one. We’ve had this in place for a while. The product itself seems to work great but I’ve had some issues with using it in the Activities. Specifically, it doesn’t always change the source input. However, I don’t believe this is a problem with the unit itself but simpy the fact that the IR receiver for the optical switch often becomes slightly misaligned relative to the Harmony Companion IR blaster. I suspect this is the result of my son moving the soundbar from time to time. It may also be in need of some tweaking within the Activity setup as it usually works when I manually change the source via the Harmony Companion app.

Overall, I think it works well and it’s much better than the manual switch I was using. I think it will work perfectly once I take the time to rework parts of the Harmony Companion setup, including the physical location of devices.
