Is it possible to make the RF433 remotes unique per fan?

[npawelek]

I purchased an iFan04-L and flashed it successfully with this code. It works great and I wanted to thank you for spending the time to put this together.

I was thinking about purchasing a few others and was a bit concerned about the remote that it ships with, being they're RF433 and appear to send out identical codes. The rooms I want to add additional devices to are relatively close proximity, either through a single floor or a few walls, and I'm trying to figure out if it's possible to use the remotes that come with it (making them unique) or get a separate smart remote to control altogether. The ability to toggle via home assistant is great, but having a physical button is critical for me. Looking for ideas to see if this is possible. Any thoughts?

Since they appear in HA as just regular fans (and non-dimmable lights) you can use other remote type devices for it. I have a lot of lights done with Lutron Caseta, for example, and I install their Pico remotes on the wall. The center/up/down I use for the fan (on/off togle, faster, slower) and the top/bottom I use for light on/off. The Caseta Pico also has a table mount that is nice (e.g. for coffee tables) and holds two.

One Pico would not be great for multiple fans unless you want them in sync (it would be fine for that). But there are lots of similar remotes and buttons out there. Keep in mind you don't need the button to control the fan -- you need the button to send a signal to home assistant, let automation in home assistant control the fan.

Thanks. Once I get my second remote, I might play with rf_receiver to determine if they're identical between remotes. The goal is to have a 1:1 remote to fan mapping between remote/controller.

I have two iFan04 and each remote only works with the receiver it was shipped with.

Perfect. Thanks!

I have five iFan04-L installed in my house. I have verified that I can control more than one fan with a single remote, and I can also reprogram remotes to work with different fans.

Thank you your effort - this is the best fan control solution I could find for home assistant (almost as good as the Insteon fan controllers in my previous home, but I won't use Insteon again due to proprietary technology and prior bankruptcy).

I setup each iFan on the bench by flashing with DC low voltage, then completing setup / remote pairing with 120 VAC - I found I couldn't complete the setup on low voltage only. I believe the OP's issue is hardware related; I'm experiencing the same issue, and the work around is a pain.

The previous owner of my home installed fans wired to one circuit breaker and didn't install wall switches. If I cycle the power with the circuit breaker, all the iFans go into pairing mode for 5 seconds and the paired remote will control all fan units. The only way to pair a remote to one iFan is to remove / reapply power to the individual unit - this requires a ladder and working with live power (or installing a temporary switch).

I tried the soft reset via the web interface and then pairing, but the iFan doesn't go into a pairing mode after a soft reset. I tried pressing (short and long) the external button on the iFan, but again it didn't go into pairing mode. It seems the only way to enter pairing mode is a hard power cycle; it would be much easier to manage the device if pairing mode could be entered from the web interface or by pressing the external button.
