BQLZR Inching/Self-Lock/Interlocked 12V 16Channel 433MHZ Wireless Relay Remote Control Switches 2 Remote Controls with 1 Receiver Board

Ideal solution for multichannel remote control. Works as expected. I've installed several of these controllers for light control.

It worked perfect right out of the box. There were no surprises. I used it to make my old motor home super modern. I hooked one channel into my generator to start and stop it by remote control and I wired another channel to my inside lights and another to outside lights so I can see outside and inside at night as I come back to my motor home in the dark.

I haven't tried it yet because of no indication of what should be (+) or (-)No instructions but it seems straight forward except powering it up with a 50/50chance at shorting it out.

New designed board. Clean board unlike old reviews. Has barrel and screw connections for board power connections.Remotes are not programmed to the board out the box.To connect remote press and hold program button on board for two seconds until it beeps then press it once more quickly. On the remote press a button (I did 2). All the buttons started working after that. Tested all 16 buttons.Board has blue LED indicator for each relay.Tested the relays with a multimeter seem ok.Tested board to remote distance by leaving the board inside and going outside and selecting a few relays from about 50 feet away. It worked and should be ok for my application.

just step down the needed 12v to 5v to send to remote igniter on push of NO contact ports A&B and boom

I am impressed with the remotes range. They are VERY EASY TO INSTALL. Although the frequencies some times interfered with other remotes...,I hope their frequencies could be easily modified... But in general they were very responsive and precise... I like them very much!

Using them for Halloween props, work well even from some distance without putting antenna up. Pushing a button on one cancels the other out for a few moments. Had to do a few resets, but generally worked quite well

Although functional out of the box, this relay board is NOT AS ADVERTIZED. Per the listed description there is supposed to be functionality to alter the functional mode from inching/self lock/interlock by altering jumpers on the board. There are NO such jumpers and no instructions on if this is even possible. There is NO documentation with the board, there is no information on how to train the relay(s) to respond to a different input signal. Also the means of packaging allowed the connector block on the board to bend, and the solder pins on the bottom rubbed the box to the extent that the entire board is covered with cardboard particles completely. Communications with seller on rectifying to provide the board as advertised have been unsuccessful...they simply do not acknowledge that it is NOT as advertised, and have provided NO assistance on how to alter function nor on how to train to new signal. This is a terrible product and shady seller.
