Hi All
Does anyone have a current working ESPHome code example they can share for the iFan04 with/without buzzer & remote control working please.
Thanks

You should be able to work it out from here.

Ditched my post from yesterday as it will only add confusion
I have it working now with RF & Buzzer under ESPHome1.19.4 - I can’t take any credit for the code, its a mashup from two other users that did the work @sliwma & @netadmindave - thanks !

Can you share a link to wear you purchased this item and if it works well without exchanging the capacitors out for US-based fans?
Really? The page I pointed to has 4 sources to buy from and specifically says
Largely identical to iFan03 with capacitors designed for 110V fans and an improved RF chip with better range.

Really happy with mine now, have a nice lovelace card for the fan and my original wall switches work the lights & fan on/off at low speed using a D1 mini. I think medium speed is a tiny bit faster but low is spot on which is where our fans run 90% of the time.
I bought direct from itead, took around 3 weeks delivery to east coast. I got 2 units.

Your ifan04.h should say
IFan04Output
Having said that, I can’t seem to get my remote to work at all, any tips?
Everything works fine in HA.
Your getting the red LED on the remote - Just checking you removed the plastic strip?
Pairing the remote, you kill power to the ifan unit, then return power to the device and press and hold any button on the remote within 5 seconds. and you should here a beep from the buzzer. I think on original Sonoff FW your meant to hold bottom right button in case that has any relevance
(I don’t recall hearing the buzzer myself)

guess I should have read the little book lol I didn’t do the 5 second pairing thing.
Thanks for getting back to me, everything is working now.

I’m struggling to get the remote to work. How long did it take to pair? Did you ever hear anything out of the buzzer?
@tmoehlman Hey Tom, the way I paired the remote was to press one of the remote buttons a few times within 5 seconds of powering the ifan04 unit on, for me it worked fine the first time, and I did two of these.
The buzzer does work for me, but only when the remote is used to function the fan. The buzzer can also be turned on/off with the remote.

@sihartley Thanks Simon. I tried everything, and for some reason I could never get it to work. Finally, I flashed it with Tasmota, and was able to get the remote to work first try. Maybe I’ll give ESPHome another try at some point, but for now I think I’ll stick with Tasmota.
Tom, the reason you struggled with the remote is that remote_receiver is not the ideal approach to processing the RF commands as they are actually a serial data stream. That can be confirmed by looking at the Tasmota implementation, Tasmota/xdrv_22_sonoff_ifan.ino at e5d576b5076874def7c990ff4ee1c3db8cf8207e · arendst/Tasmota · GitHub. I was getting too many misses with the remote_receiver approach so I worked with @ssieb and he threw this together, for handling the serial I/O and turning the RF commands from the Sonoff RM433 remote into trigger actions custom_components/components/ifan04 at master · ssieb/custom_components · GitHub. I will post my YAML config in the next couple of days once I have had the ladder out and completed the install. I refactored away the custom IFan04Output class as that can be achieved with an output template
Sweet! I’ll give it a try.
Looking forward to seeing your config.
Here is the config, I don’t save state and the light does not come on with the power, you have to turn the light on yourself, which is actually one of the reasons I replaced the original Hunter remote as that would always come on after a power outage. I have stuck with the relay configuration used by @mattcony above, but I did see this article that discusses a different relay sequence.

Great to see others are having success with the ifan04 – i just got mine and attempted to flash, but even with switching the RX/TX around and confirming the device is getting 3.3… i can’t get esphome to recognize the device locally.
I’ve tried both booting up while pressing the big white button, and booting up without pressing the white button. The later ends up with the device beeping at me consistently for some unknown reason … but the former is how i traditionally flashed sonoff’s, but esphome doesn’t recognize the ifan04…
wondering if i’m missing a step, or if there was a hardware revision i’m unaware of… any help would be appreciated
I too struggled initially to get the device into flash mode. I tried the ESPHome flashing tool for Windows and then Tasmotizer for windows tool. It was not until I was using Tasmotizer that I realized that my new ESP flashing device wanted RX to RX and TX to TX, I did not the go back and try the ESPHome flashing tool for Windows. It is a couple weeks since I did it, but I believe I might have held the button down for the entire flashing process. I used Tasmotizer to take a backup of the original firmware just in case 
Any further information on the correct relay sequence? I have tested other fans without custom firmware and it seems that they toggle on more relays for low and medium speeds to help the blades start up. This thread discusses the issue on an iFan03 in tasmota, but I am not sure how that would translate to ESPHome. Something like this?
# low speed
- switch.turn_on: fan_relay1
- switch.turn_on: fan_relay2
- switch.turn_on: fan_relay3
- delay: 3s
- switch.turn_off: fan_relay2
- switch.turn_off: fan_relay3
Why is relay 1 set to on for medium and high?
The article you linked gives a very good explanation of the Tasmota code. The complicating issue is that is seems like they also discuss the impact of capacitors in series, so without knowing the individual ratings of the capacitor associated with each relay and the Physics knowledge to correctly calculate I went with the existing settings of @mattcony. The fixed delay sounds like a good workaround until you consider the transition when the fan is already running. You only really want to enable the higher speeds at startup when the fan is not already turning. I will give tracking state some thought.
