QIACHIP DC 12V Wireless RF Remote Control Switch, 4 Channel 433MHz Relay Module Transmitter Receiver Kit, for Lights, Fan, Garage Door, Motor, Truck Trunk

This remote switch was easy to configure and works amazingly well. It can control 4 different circuits independently, and can be programmed as momentary, latching or toggle mode. All four switches must be configured the same type. Comes with two remotes with batteries already installed. The remotes feel good quality in your hand. You must pair the remote transmitters with the receiver on initial setup. It's not hard to do, but there are 0 instructions that come with the unit, however there is an instruction sheet for the item as one of the pictures on the Amazon sales page. In standby mode, it draws only 11.7 ma. I'm using this to control 4 different LED lighting zones on my truck camper. I have it wired up in conjunction with some panel switches, so I can bypass the remote controller and control the lights manually with the panel switches in the up position, or through the remote control in the down position. That way if the remote controller should fail or I don't have the remote with me, I still have manual control of the lights. Also, this allows me to eliminate the parasitic drain when not in use. So far, this little unit is performing as advertised, and I am very happy with it.

CONS The wire goes into a terminal block with the little screws and green sides ( this is in my RV ) i'm alway worried that the wires are going to short out with this style. takes a moment but you can find the information on the PCB basically its every third wire is input ( or ground depending on your set up ) on either side is NC/NO the little plastic enclosure was worthless as i was not able to pack my wires in ( 12-16 ga wires ) i'm using 3 of the relays. PRO it has an antenna that you can strech out / replace should you feel so inclined. The remotes are amazing. it says it can store up to 20 ( I was thinking of using the 433 mhz wall plates i'll let you know how it turn out ) range on the remotes is very good . Neutral no documentation was provided, if you do look around there is a picture that says hit the button 8 times to reset and 3 times to get the unit in toggle mode it is shipped in momintairy mode. you need to fiddle around to figure out which is A VS D block. a note on the PCB or yet documentation would have been nice. over all I really like it, if it brakes i'll provide an update. ( Id most likely just buy another to replace it )

So the instructions only come with 3 modes. And they are tied to each remote, not individual buttons. Wanted two toggle and one momentary buttons. Luckily after looking online I see there is a 2 M + 2 T mode so that will work perfect. Otherwise so far seems to work great. Easy to reset remotes and reprogram to new modes. Curious about range, but not fully installed yet. Just did preliminary testing to understand how it works and which buttons are to which relay. You have to jumper all your connections to the 12v thought it would be better to have that done already, but this way gives you the option to turn on/off DC and AC items so IDK. I'm all the same 12v so not using that feature. Potentially powerful little device to turn on and off almost anything remotely.

so...I bought two of these. you can use the same remote to control both relay modules (just pair them at the same time). I use one at the shop to open, stop, and close the bay doors (set the momentary contacts in parallel with the up and down buttons and series with the stop) because the type of door opener does not allow for a typical garage door opener. but I still had one spare channel...so I wanted that to open the facility main gate. downside is that the main gate was about 200 meters away, so I put in the second module up there. these are great little rigs and one can control just about anything with them (maybe need some extra relays and stuff depending on what you wanna control). only downside is the remote range. maybe it would be stronger with better batteries, but you get a pretty crappy range of control maybe 20-40 feet. upside is that you can just extend the pickup antenna with a piece of insulated wire electrically connected to the coiled antenna wire inside the module. I ran it up the side of the shop so I can control the bay door from maybe 140 ft away.

They advertise 50 mt range, tried it in a tennis court and the range is good enough from 8 to 10 meters. Will return it

Easy and straightforward to install. Circuit board is well designed with plenty of protection. Each relay is 100% independent of the others, allowing you to configure the 4 channels however you wish. Channels cannot be grouped (fire two relays with one button). Keyfob fits well in the hand and has a res light to confirm you are pressing a button. It's not too heavy and feels to be of good quality. Circuit board has good ripple rejection, and the signal is quite long range.

Overall I am very happy with this remote/receiver kit. I can only attest to the "momentary on" setting as it's used for lock-unlock-trunk. Terminals are well labeled and the relays are working great with around 15 amps at 12VDC. The antenna comes coiled up tightly, I got about 100 ft of range in a parking lot when coiled. Since I installed under the dash behind my glovebox I uncoiled it and placed it flat directly under the dash surface.. Well over 500 ft range in an open area now. 300+ ft in a parking lot. This unit works as advertised and is surprisingly well made for the price.

First, the instructions need careful reading. There is not a word extra. The instructions say there is a LED. True enough if you have either great eyesight and glasses or if it worked so you could find it. I bought 2 complete sets and neither receiver worked.

As advertized. Works well with my project. May be better if their is a light indicator on the remote that the relay is energized.

These kits can be used to enable remotes to control almost anything you can think of. Easy to program and wire up to operate mulit functions. The only thing I found anoying is the cut out for the wire to connect into are too small so I cut them out bigger to allow the wiring to fit into the appropriate slots on my apprication. I used them to upgrade my trave trailer awning to enable remote control from anywhere. These units can transmit 40 to 50 feet. Great buy for the money

What can I say ,I'm a gadget lover and these are fantastic, I have one installed on my front door with appropriate latch and garage door works grate and it has a good range, very recommandable product
