Setup: HTPC with FLIRC-SE, Harmony 900, Harmony One. Problem: Flirc becomes unresponsive at random times. Worked great for a year, but the last month its been unstable. Might work perfect for a few minutes, then goes "deaf" and ignores most commands. Spamming or holding buttons works, so the commands are correct. What I know so far: Its not the remotes, they work flawlessly with all other connected devicesLatest firmware and software Noise cancelling and harmony settings dont make a differenceNothing changed in my setup: Same devices, placement, lighting, etc. Covering the ir-receiver with a piece of cloth seems to solve it - noise of some sort?So my working theory is that theres some sort of noise disturbing the flirc, blocking out my remotes signals. But I can't figure out what, I didn't change anything in my living room besides the sofa (replaced black leather with light grey fabric) and I can't imagine THAT is the problem.. And whatever is interfering, doesn't seem to bother any of the other 8 devices I control with the Harmony remotes. There has to be a better solution then draping my T-shirt over the HTPC!
