Not sure if of any use to anyone but just bought one of these to try and works fine with LWRF. Easily learnt to any remote (including phone app)

They also do 1, 4 and 12 relay versions
Going to use it to control my kitchen LED cabinet lighting.
That looks interesting, Simon – and they are very cheap!
Can you pair each relay separately, or is there just one device code that switches both?
Yes both pair separately.
You can use 2 buttons – one for on and one for off or one button that toggles or has a momentary effect.
This is programmed using the small button next to the relays
Got mine up and running now, works fine and is approx 8m away from WIFI link in another room.
Many thanks, Simon. I think I’ll invest in one or two of these.
Nice find, 5A switching for the tenth of the price of 2A switching in the LWRF inline relays is very attractive!
Do these relays come with wiring instructions?Running RFXCom with Domoticz on model b raspberry pi. LWRF dimmer switches, PIRs and plug sockets. Some Homeeasy switches, harmony hub controlling AV and air con. Geofencing with Pilot app. Tado for heating.
I haven’t got one yet, but I suspect raw from China they have no or very little documentation. They do, however, look pretty straightforward to use. The basic ones have a 0-12V DC input and then 3 contact c/o per relay. There is a slightly more expensive one that is powered from mains input with its own little inbuilt supply. That may be more convenient as a stand-alone self contained mains powered unit and it comes in an enclosure.
No, no instructions came with it but as btidey says its pretty straightforward – 12V DC supply and then SPCO relay contacts.
Not seen the mains powered ones, might look at getting that instead as got a 12V PSU running it.
Mine has been up and running now for a few weeks now and not a single problem.
I assume this is the mains-powered, enclosed unit? 10A switching too. Will report back when it arrives sometime within the next 6 years…
This is the one I’d seen
The other one says out of stock. It is however 2 channel and has a remote. The contacts are just a make to give 240V out whereas this one is contact free changeover.
Hi. I got mine today. I connected a 12v supply and was able to see the LED lighting when I push either of the buttons but now I’m stuck. Can someone help me to find how to connect the output and to pair the device please? Many thanks.Running RFXCom with Domoticz on model b raspberry pi. LWRF dimmer switches, PIRs and plug sockets.

I had to do some trial and error but I pressed the button 3 times to get it into one button on and one button for off and then pressed and hold it to enter learn mode. pressed the button on the phone and it double flashed I think. repeat for the other phone button.
I’m still stuck trying to wire this up. Could someone post a wiring diagram please? Much appreciated.Running RFXCom with Domoticz on model b raspberry pi. LWRF dimmer switches, PIRs and plug sockets.

so these 12v relays use the LWRF protocol? so i cn use my wifi link to control?! (without an rfxcom?)
do they do mains versions?
I’ve got mine wired up:
+12V to VCC
0V to GND
Then use 1A and 1B for normally open contacts.
My relays say 5A @ 250V though I use it only to switch low voltage 12V LED lights .
IF USING MAINS ELECTRICITY ON THE RELAYS REMEMBER THAT PARTS OF THE PCB WILL BE LIVE !
Yes they work straight from the wifi link, just like any of LW official RF receivers
