433Mhz Universal Wireless Remote Control Switch DC 12V 1CH Relay Receiver Module RF Transmitter for Access Control,Lights (Transmitters 2 Button+ 2 Receiver 1CH)

Dislike: the plastic enclosure needed trimming so that the wires can pass through.Like: instructions are clear and easy to follow. I measured the current draw @12VDC in eash of the 3 modes.Standby: 6 mA, Toggle (on): 67 mA. Latching(on): 37 mA.I'm using 3 URGENEX 3.7v Lipo Battery 600mAh with JST Plug 1S Li-Po Battery with X5 Battery Charger for UDI U817 U817A U818A V959 V222 V929 RC Drone Quadcopter 5PCS Aircraft Batteries in series to power this receiver. The receiver needs 10-14 VDC. Using the Latching mode reduces the current draw by half. You then use the key fob (A) button for turn on and the (B) button to turn it off. Range is pretty good (433 or 315 mHz). Using a ATPWONZ 4 Pack Junction Box ABS Plastic Dustproof Waterproof IP65 Universal Electrical Boxes DIY Case Project Enclosure with Fixed Ear Compatible with Electronic Project (3.94 × 2.36 × 0.98 Inches) to mount the battery and receiver outside.

Good range and programs like the video shows. The only minor issue is that the case is no good, you cannot get the wires out with it in the case, you would need to cut part of the case away to make it work. There are no mounting holes, and no lip, so adhesive seems to be the only way to mount it. Would buy again.

Very simple and easy to use. Connect power and whatever you want to control. Case is bad in that the holes for exiting wires is terrible. Just cut out a space with razor or scissors

Working modes are easy to program in ten seconds and stay in memory. Functionality exceeds expectations. My only gripe is the boards have no mounting holes and the enclosures are junk. This is amplified by solder contacts coming near the edge of the boards. Basically, they will need to be individually zip tied. The screw terminals are much more secure if you tin the wires before inserting.

value for money

Works fine for my application. Printed instructions were good. Note that the keyfob requires two CR2016 batteries (a single battery would have been more convenient).

This is exactly what I was looking for. I bought this to add a remote shutoff to my generators. I was able to use this to accomplish this task with relative ease.The remote buttons seem very rubbery and will probably not last long but I’m a maker and I’ll probably just create a new enclosure for it if I need to. The plastic enclosure that came with the relay module seems like it was originally designed for something completely different but that’s not really important. I was able to use the remote at a distance of about 500 feet.

Works better than I expected range is great as well as sensitivity, I have used a number of these remote controls now and I'm happy with the product.
