Some common and fairly useful little remote control modules. The unit is let down by having a relay with 125V contacts (on a 220V unit) and no thermal fuse to protect against relay contact failure.
The ability to remember quite a lot of codes from a wide range of remotes like wall switches and keyfobs is useful.
Note that clearing/programming codes requires the pressing of a button on a live circuit board. To clear all codes hold the button down with an insulated tool until the LED strobes. To program a new device, press the button once and then immediately press the desired button on the new remote. All devices will have to have the same operating frequency and transmit compatible codes.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

It’s a real pain that almost everything uses 433MHz as that’s right inside the 70cm amateur band.
I’d love to set up a weather station in the garden but I’m sure that it wouldn’t be too keen to swallow 50W at close proximity, and I’m sure it would also generate interference.
Can you delete just one remote, vs. all of them?
Great devices until they fall into the wrong hands .I have had issues with outdoor solar lighting I programmed one on button a and the the button b .Button a turns on a and b and button b turns on b only .Strange .left it alone good enough to light the pathway long before you get to it .Almost 75 meters !
I get regular emails from banggood, and one of the more recent ones featured that little module you showed in this video. There's a third mode, leaving the link off altogether, I think.
Stuff disappearing on route from China, it's routed via Hong Kong and the Hong Kong Post Office is not very honest.
Got a remote relay 3 ch unit with key fob operation.Mine can be pulse or latch with dip switches. Very useful with 12v batt and vintage horn in boot. Amusing in car parks.Yes I'm a child I know
Hi Clive sorry to be a dummy but how do you work out the power factor if you don't have a hopi ?
Do you know where I can purchase UK compliant versions of these wireless switches? I've seen similar products sold in the U.S. but was unable to find anything for the UK.
The parents have got a hallway with a couple of……. luminaires….. that they'd like to be able to controls from several locations. Currently the only switch for these is in a really shitty place. They're not too keen on me chasing wires into the 300 year old stonework though.
i have “battery-free” ones, which will get the energy to work by physical pressing 🙂 you may check these to 😉 greetings from estonia.
Does anyone know what happens if more than a single button is pressed? 😱😱😱
Clive, the slot in board, wouldn’t that be to isolate the crystal & supporting from the antenna?
So, were these rated to be in accordance with your national RF standards like those in the U.S. from the FCC? I have doubts that the broadcast complies with the filtered, narrow band requirements for radiating a signal to ensure it does not interfere with other systems.
Safety and quality oversight are not at all the stronger points with Chinese designers and manufacturers. I remember some pharmaceutical pills manufactured in China that they coated the pills with, of all things, leaded ROAD PAINT. I mean, can you imagine how bankrupt the perpetrators had to be in the arena of ethics to coat oral pills with road paint?
Wow BigClive!
Based on your instruction I knew you were an intelligent man, however, the fact that you know about the 3rd switch… you must be an Oxford man.
@BC – Any product codes for these wireless relay modules & switches ???
.
Used one of those in my RV to control the color rear camera I mounted on my roof ladder so I could use it as a rear view device. The built in device would only show my towed vehicle and not what traffic was like. They said if I left the wireless transmitter on all the time, it would burn out the transmitter. Worked great for that.
Clive, is this similar to the sonoff itead things? And what are your thoughts about that?
You'll wish you never trusted non compliant Mains voltage Chinesium Landfill products, when you're picking your way through the remains of your house and your insurance won't cover your losses.
