- The easy way: IR
Choose a fan that has an IR remote and you can control that with Logitech Harmony integrate it to SmartThings that way.
- The Maker Way
Wire a relay in past the point of the button. This will, however, violate the fans warranty and you have to know exactly what you’re doing to maintain fire safety standards. So I don’t recommend this in general, but there are some community members have done it.
3)a) Automatic button pusher, DIY
You can build an automatic button pusher with an actuator. These are actually pretty easy, and you don’t have any fire safety or warranty issues because the pressure is just pushing the existing button. The problem is that most of them are big and ugly. But it can be done.
3)b) automatic button pusher, 21st century style
There are several companies working on making small, aesthetically acceptable, networked button pushers.
None have come to market yet. The one that looks most likely to succeed based on engineering talent and backers is from a Korean company called Prota. They are calling their devices microbots, and the button pusher is just called Push.
They’re still in development so you can’t quite tell what the features will be yet, but they have been selected by Amazon for their “exclusive” program and right now are scheduled to start selling in August. (Again, I don’t know if they’ll make that date.)
I’m not doing a pre-order on these, but as soon as they’re available from Amazon I do intend to try them.
That’s important to note that the Prota are Bluetooth devices. They will not work directly with smartthings to begin with. And we’ll have to wait until they’re actually released to see what, if any, kind of integration is possible. They’ve promised IFT TT integration, but will have to see if that actually appears. If it does, that will give you smartthings integration.
But in any case I do expect to see several more devices of this type available for around $40 or less over the next 15 months.
So if you can be patient, it’s quite possible that you’ll have a device of this type that you can make work with most fans in the next year or so.
