SONOFF iFan04-L Wi-Fi Ceiling Fan and Light Controller

Compiled by SmartHomeWorkflow Research · SONOFF · Switches & Dimmers · ~$19.9 (at time of research — read from SONOFF's own US store listing, which showed it as a 'Sale price' rather than a list price, so it is a promotional figure and not a stable one. Never treated as a live price.)

⚠ Similar names, different products: iFan04 is sold as two electrically different parts under one product name, and picking by name alone will get a US buyer the wrong one: SONOFF states 'If your local input voltage is 100-130V, please select iFan04-L; If the input voltage is 220-240V, iFan04-H is recommended.' This record covers the iFan04-L. The two also differ in what they will drive — the published tungsten and LED light-output limits are quoted by SONOFF for the iFan04-L specifically.

Compatibility

? Inconclusive means we researched that ecosystem and the evidence doesn’t settle it — the catch says why, and the sources are listed below. It is a statement about the available evidence, never a verdict on the product. A Setup Check researches your exact setup where the official sources don’t answer.

Protocols: WIFI^[1]

Subscription reality^[1]

✓ Works without a subscription: Yes.

Vendor account required: Not established — we have not sourced this yet.

No plan, paid tier or recurring charge is named on SONOFF's product page for this controller, and the eWeLink CUBE OS route it advertises is described by eWeLink itself as 'A free self-hosted local system'. We record no subscription on that basis. The honest limit is that this is the absence of paywall language on a product page rather than an explicit 'no subscription' statement — and the eWeLink mobile app, which is the main way you would control this thing, has historically carried optional paid tiers that this product page does not discuss.

Maintenance reality^[1]

• Works without the internet: Inconclusive — we read the vendor's own material and it does not answer this either way. It does not mean the product fails without the internet.
• Replaces the fan-light controller inside the fan, driving fan and light on separate outputs. Electrical specification as published by SONOFF: Input 'AC100-240V 50/60Hz 5A'; Light Output 'AC100-240v 50/60Hz 3A'; Fan Output 'Max. AC100-240V 50/60Hz 2A'; and, quoted for this variant specifically, 'Tungsten lamp Output(iFan04-L) Max. 360W/120V' and 'LED Output(iFan04-L) Max. 150W/120V'. Radio: 'Wi-Fi IEEE 802.11 b/g/n 2.4GHz' — 2.4 GHz only. A 433.92 MHz handheld remote (RM433) is in the box and gives direct manual control of fan speed and light independently of the network; it is not a smart-home standard and is not listed among the protocols for that reason, but it is why this controller keeps working as a fan control when the network does not. Three fan speeds (low/medium/high). SONOFF states 'no hub required' and 'Built-in WiFi module enables direct eWeLink app connectivity without requiring additional hubs'. Warranty as published: '2-Year Hassle-Free Warranty'. It depends on eWeLink's servers: the documented app and voice routes all run through them, SONOFF documents no way to control it on your own network alone, and the local alternative it does advertise — eWeLink CUBE OS — is separate software you have to run yourself.
• Security updates: No security-update support date is on record for this model yet. We haven't yet checked whether SONOFF publishes one, so this is a gap in our research — not a statement about the manufacturer.

The catch

Buy the right letter. iFan04-L is the 100–130 V part and iFan04-H is the 220–240 V part, sold under one product name, and SONOFF's own note is the only thing on the page that tells them apart. Beyond that, the honest split on this controller is between two ecosystems that are documented and three that are advertised. Alexa and Google Home are named directly and work through eWeLink's cloud. Apple Home, SmartThings and Home Assistant are reached only through eWeLink CUBE OS — free self-hosted bridging software you run yourself, described in a sentence about 'SONOFF WiFi devices' in general, with no published list of which models it carries, which is why this record leaves those three cells open rather than claiming them. It is an in-fan controller at line voltage with published output limits worth checking against your fixture (360 W tungsten or 150 W LED at 120 V, 2 A fan), and it is 2.4 GHz only. The 433 MHz remote in the box is the quiet upside: it drives fan and light directly, so the fan stays a fan when the internet is out.

Who it's for

An Alexa or Google Home household with an existing ceiling fan that wants app, voice and schedule control cheaply, is comfortable wiring a module into the fan with the breaker off, and can check the fixture's light load against the published limits. The included RF remote also suits anyone who wants a physical control that does not depend on the network. Look elsewhere if the household is Apple Home, SmartThings or Home Assistant and you are not willing to run eWeLink's self-hosted bridge software and find out for yourself whether this model is carried, if only a 5 GHz network is available, or if the fixture's light load exceeds what SONOFF publishes for the -L variant.
