I haven’t had a chance to start hacking the fan with openhab yet – too many projects, and the uncertain interoperability wasn’t a show-stopper for me – but I did take a closer look at some of the components during installation.
The motor is DC and the controller uses three wires to control the fan speed and direction, so the iFan will not be compatible, unfortunately.
The LED array has pairs of yellow and white LEDs and two ICs (SDS3703P and SDS3513S) to support the lamp color and dimming. The signaling is via the two AC wires for the lamp.
Controlling the motor and light directly by replacing the existing remote receiver seems like too much work for me.
Regarding the fan itself, I think it’s a good deal, especially for the price and I ended up buying a second one for another room. The wide base seems a little bulky compared to the more common pole-hung fans on the market, but this makes it much more stable and I didn’t have to use weights to correct any wobble. I thought the light was OK, but my wife finds it harsh, which is why the second one we ordered is without the light. On that one, the edges where the blades butt together is exposed and the differing wood colors and grains are very noticeable, especially when the fan is spinning. If this may bother you, consider getting the model with the lamp or the cover plate.
The remote controls for both fans give the impression that Ikohs is not a fan or usability specialist. I have both fans wired directly to unswitched power to be independent of existing lighting and I think Ikohs uses these mainly on switched circuits. The light control on the remote, for example, cycles through the different warmth colors when switching between on and off. So when I turn the light on, I need to press the button a bunch of times until I get the warmth I always want. The remote for the fan without the light has two unused buttons and a different layout than the other fan. If we had these fans on regular wall switches and used the remotes only to adjust settings, this wouldn’t be a problem.
In the end, though, we’re pretty happy with these fans. We have 1-2 more rooms where we may eventually add fans and if we do, we’ll very likely stick with the Ikohs fans even if I can’t get them working with openhab.
