In this video I modify my IFAN03 fan speed switch to use on a Westinghouse Ceiling fan on 120 Volt mains.
The IFAN03 from Sonoff comes from the factory in only 1 version. There is now an IFAN04 that comes with the ‘correct’ caps for the US market. However, in this case, that one would have needed to have been modified ad well because this fan used a different size altogether…
The video appears long, but much of it is demo footage of the fan operation at the end of the video.
This version sets the speeds properly in markets where the mains voltage is 200-240 Volts. Unless you run the full split phase to your ceiling fan (much not recommended) the fan will barely spin and be unusable on low speed, medium will be around where low speed should be, and high speed is unaffected (Because high speed is the fan motor wired straight thru to the mains.)
In this video I show you my fix for this. I remove the capacitors that were designed to run the fan from the fan control itself and install then into my IFAN03 so that it spins at the original factory intended speeds.
If you have an IFAN02, the conversion process is the same. IF you need new caps, I have found some 5uf caps that work on most us fans and can be found on EBay with a search.
REMEMBER, the MQTT Topics, device names, and possibly formatting of the code may be different on your set-up. In particular I flip my Topics around from the standard Tasmota way, so if you run into problems, please check that the Topics in your YAML code matches your Topics in your Tasmota Webui console.
