 Is there still development going on for this product? I would love to see the rf + wifi version of de Sonoff switch as seen in all the pictures and on youtube.

Can I add my own rf-receiver to the board? The holes and wiring are already present..

RF would make it much more versatile, you don't always want to start an app just to turn on the light.

Hi Joost Janson, yes, we are still developing more Sonoff versions, like low voltage version, version with temperature sensor. And we have our Sonoff RF version which has a RF receiver inside available on our online shop https://www.itead.cc/im151116003.html  Note: the controller is not included in the package. 

Yes, you can replace the 433Mhz RF receiver to other Mhz receiver. 

The RF transmitter has 4 buttons, does this mean you can only control 4 devices per remote?

Or does it mean you can only control 4 devices no mater how many remotes you have?

Hi there, what RF receiver module ITEAD's Sonoff RF and Slampher use is this one: https://www.itead.cc/rf-receiver-module-433mhz.html.

Be careful, the other Sonoff version such as Sonoff, Sonoff TH, Sonoff SV do not have 433 RF module.

Specifically, I'm looking for details/datasheet for the RXC6 433Mhz RF receiver used in the 433Module. It's shown in the link below but without a datasheet.

@Tuicemen The RF Remote has 4 buttons means it can control 4 different devices. If you pair it with A button with Sonoff 1, then you can use button A to control Sonoff 1. So you can totally control 4 different devices. And of course you can cancel the pairing and re-pair with other devices.

@Elsie,

that realy didn't answer my question.

Say I have 5 Sonoff and I wish to control them all via RF. Since the remote only has 4 buttons will a second remote work?

Also could I pair 2 Sonoff to button "A", 1 to "B", 1 to "C" and 1 to "D" enabling control of the five devices?

Hi Tuicemen, one button one device.

Ok thanks, One more question.

If my neighbor also has a RF Sonoff configured on his remote to  paired to "A" would it also control my device paired (set) to "A"?

That situation is rared. One can pair with the RF remote controller only when the device set in pairing state. Read this blog please: https://www.itead.cc/blog/user-guide-for-sonoff-slampher

I have a RF Sonoff and also a seperate 433Mhz receiver. I was able to pair four different button to one receiver. According to the doc the 4 output D0-D3 should toggle low for 200ms, but this is not the case for either of them. Output D0 to D3 stay low at all times and only the led is flashing when it recognizes a paired button being pressed. I opened a ticked but so far no response on this issue.

So I really need a different RF option.

Something like http://support.iteadstudio.com/support/discussions/topics/11000002347

This would allow multi devices to have the same RF address as well I could control up to 256 different devices.
