thanks for your input!
Because 2 devices are in the closet with the hub, and the TV is outside the closet, the IR signal does not reach the TV. The Harmony Hub has a small wired external transmitter, which I placed outside the closet to get to the TV.
I found those too, but seems they are not really available either (in The Netherlands?), at least not in stores I normally use for hardware.
An exact replacement is not needed, I just need a device that can replace the functionality I described in “current usage”, basically: be the bridge for IR commands from openHAB.
Cool device! But not yet available and seems a bit overkill, I’m not interested in a remote control, I do not use it. I use a custom OpenHAB panel on my home-automation-tablet to switch channels etc. using the Harmony Hub addon. In my experience the addon has a more stable connection to the hub than Harmony’s own Android and iPhone Apps.
Did not think of that, definitely worth the try!
Certainly interested. I’ll try to replace the power supply first …
