I use an IR eye for now on the X1 and it seems to work OK, but response is slow: it is also possible you are overloading the IR receiver by placing the IR emitter directly on it: I can adjust the level of the IR signal and usually run it as low as possible so it works reliably, without overload: you might try moving the IR an inch or two off the eye to see if that works. And if you can adjust delays in between commands, that might help
IP commands would make all these issues moot: and make a lot of CI's (custom integrators) very happy
Thanks for the great info Mark! It was explained to me elsewhere that the X1 uses XMP style IR and many repeater systems don't processing XMP that well. Here's the broader picture for what I'm doing - hoping you may have some suggestions:
- In the theater I'm using a Harmony Ultra. Not my first choice in a remote, but I very much like its Z-wave integration so I can control my LIFX lights and integrate with SmartThings.
- The Harmony transmits RF to its "hub". Emitters attached to the hub then blast IR.
- I had the Harmony hub in the equipment rack in another room, but the remote was complaining often that it couldn't reach the hub and move it closer.
- There was no way to move the hub closer so I located it on top of my projector in the theater. I point one of the emitters from the hub at the projector, and the other one I point at an IR->RF device also sitting on top of the projector (this one https://amzn.com/B00023KG40
- In the equipment rack I have the RF->IR receiver. This picks up the transmitted IR codes (over RF) and blasts they to the area in front of the equipment rack. All equipment in the rack responds perfectly and the first time to all commands. Except for the X1. That only respondes to maybe 1 or 2 commands out of 10. You can tell by how the green light on the X1 blinks when it receives a command from the remote.
- To improve that further - the RF->IR blaster has a port for a wired IR emitter/blaster. So I ran a cable from that port over to the rack and positioned the emitter right by the "eye" of the IR receiver on the front of the X1 (I am using the rack mounted version of the X1).
- The placement of this emitter was extremely finicky. I was able to test the reception by pressing codes on the remote and watching to see if the green light on the X1 blinked to indicate it received the code. By dong this I found an exact position where the light would turn green with like 30 out of 30 presses of a button on the Harmony remote. I thought for sure this solved it (even moving it as much as 1/16" was the difference between perfect vs shotty reception).
- However when trying to use the Harmony remote with my setup going - meaning projector on and all equipment on, the reception of the IR codes is still quite poor! I'm not sure what's causing it. I have another emitter product I tried hooking up and this flashes when it sees IR codes. And it is flashing quite a bit and flickering all the time in the equipment room even when I am not pressing keys! Apparently the IR->RF device is constantly sending signals or some sort of noise. As soon as I unplug it this other emitter stops flashing - meaning it is no longer seeing the noise. So I can confirm that it is the IR->RF RF->IR adding noise in the equipment room. BUT with the emitter right next to the IR window on the X1 I would think it should still get the IR codes cleanly. FWIW I also notice that every once in a while the X1 misses commands from its own remote when sent in the theater.
Any thoughts on how else I may be able to go about this - even if it involves new hardware and/or software solutions? The issue is very frustrating, as I do not want to have to use two different remotes at the same time like I am doing now. Its so frustrating in fact that I am considering switching to FIOS or DirecTV (where there is actually 4K content!!
