Fan/Light control switch - yes, again

I want to start this topic again because my situation doesn’t seem to quite match the other discussions anywhere else I’ve found.
I’ve got ceiling fans in almost every room in my house. Most of them appear to have been installed by the builder and have “the red wire” in the switch box.
ALL of them are currently wired to a single pole switch which cuts the power completely when turned off.
What I want:
Preferred - to be able to control the fan’s speed and the lights dimming from a 1-gang sized switch.
Acceptable - for the fan to be controlled exclusively from the pull-chain and the light to be controlled on a dimmer from that 1-gang switch.

Are there recommendations on the hardware I would use to do this?
and in the case of option 2, how would I go about wiring it?

I’m in a same situation as you are. Note that there’s nothing supported by SmartThings at this time!
There’s some discussion going on in this thread : Ceiling fan controller? , but I don’t think it fits well to the solution you and I wanted.

However, I’m thinking of a different approach. There’s this China product Broadlink that allows you to control Infrared and some RF’s. Those universal fan controls today are usually RF 433 / 315MHz.

I ordered this to hope that I’ll be able to integrate with ST :

I am going to pair with this:

Dimming wasn’t a priority for me, but I think this allows dimming. You have to double check.

More research to be done. Let me know if you come up with a better solution.

I’m interested in this too. Let us know if you can get it to work. Unfortunately, none of the ceiling fan kits I looked at seem to use 433 / 315MHz. The ones I’ve seen were 304 MHz, 308 MHz and some other weird frequencies.

Do you happen to know make/model numbers that use 433 or 315 MHz?

@Chris_Sanner with only one hot wire going to the van you’re only option is “virtual switches” on the wall and module(s) in the fan canopy. I settled for being able to control fan or light from virtual switches on wall. no dimming, no speed control.

Check the very last post for a link to my github with the device type and smartapp

This wireless receiver came with the Hunter fan I recently installed. It says that it’s operating at 434MHz. I can only hope that will work with the Broadlink device. Time will tell once I get the unit

Where did you buy it.?

I bought the fan from Menards, and it came with the Hunter 99118 remote and transmitter. The same remote and transmitter :

I was planning to Hunter 99111 with the assumption that the frequency used are going to be the same at 433.92 MHz AKA 434 MHz. Worth a shot.

Thanks. Good to know. I bought Harbor Breeze kit for $19 at Lowes, but it turned out to be 304 MHz. Going to take it back.

Interesting… If found one on eBay that looks exactly like in your picture, but the sticker clearly says 350 MHz. Go figure.

Ok, I did some digging around FCC database and found 8 Hunter remotes (out of 50) that use 433/434 MHz frequency:

| Model        | FCC ID  | Freq    |
| Hunter 99112 | IN2TX37 | 433.9  |
| Hunter 99116 | IN2TX36 | 434.0  |
| Hunter 99118 | IN2TX40 | 434.0  |
| Hunter 99119 | IN2TX43 | 434.0  |
| Hunter 99121 | IN2TX42 | 434.0  |
| Hunter 99123 | IN2TX41 | 434.0  |
| Hunter 45012 | IN2TX73 | 433.92 |
| Hunter 45051 | IN2TX72 | 433.92 |

Found one on eBay for $12.99 shipped :smile:

Nice!! How did you get the model number from FCC website? I know Lutron (grantee: JPZ) has a whole bunch of 433-434MHz as well. I’d like to know the models

FCC requires a picture of a label with model number and FCC ID. :smile:

Add Hunter 99111 & 99120 to the list. Both are on 434MHz frequency

So, I got my Hunter 99110 Fan Controller Kit (433 MHz) from eBay and took it apart. Interestingly, it does not use cheap analog Tx/Rx modules found in Chinese fan controllers. Instead, this is a fully digital design. The chips are made by Indie Semiconductor (former AyDeeKay LLC)

Remote (transmitter): M34228
Controller (receiver): M37473

These chips are not listed on their website (they’re probably custom-made for Hunter), but there’s a couple of close matches, which are Cortex M0 cores integrated with 433 MHz ISM radios.

I was hoping for something more familiar using PT2262 encoder chip with known data format. This one may be difficult to decode without knowing what message format they use.

Hi. I’ve got the very same device you picture here. It came with a Hunter fan recently purchased. The wiring is not an issue, but nothing in the literature shows the physical mounting location of this device. It clearly must mount below the ceiling box in the fan canopy area next to the ceiling. Yet, among all the illustrations in the literature, the location of this unit is not shown. Even the illustration of the wiring for this gives no indication of placement. I see no obvious workable solution. Where and how did you install the unit shown in this photo?

Pretty much the same like instructions from youtube

Thanks. That was just what I needed. Cheers from Austin, Texas. Take care, b2e

I assume the Broadlink solution did not work for the fan controller? I purchased one but it has limited instructions and it hard to confirm if the Broadlink supports the same frequencies as the Hampton Remote.

Broadlink or geeklink, both won’t work. They use UDP instead of HTTP protocol. Sorry to say this is end of the road for broadlink and geeklink solution.

You need to look at your Hampton Remote, check it against FCC database. If it’s showing 433, 434, or 315 it would be compatible with Broadlink. if it’s other than those frequencies, then you’re out of luck

You can try this if you don’t mind on getting your hands dirty by building a 433MHz bridge

or you can invest in this

I have Hampton bay fan/light combos around the house. All just work with a single light switch and an IR remote. Anyone have any idea if there is a solution to this problem yet? I’d really like to integrate the fan and light separately into Smartthings.

I assume you mean RF remote and not IR
