Today I got a bunch of packages, one of them contained some relatively cheap 433Mhz Relay modules.

Very little documentation on hot configure this, but I was able to work it out.

Here it is

Before starting, the unit should be powered by a 12 volt DC Power Supply

Clearing the Module

After the unit is powered on, you should first clear the codes that were on the unit.

1. Click the button on the unit 8 times,
2. The flashing should indicate the codes unit has been cleared.

Non Latched Mode

Some also call this Jog Mode.  In this mode while you have the button pressed on the remote the relay will switch

1. Press the unit 1 time
2. Wait till the LED lights up
3. While the LED lights up send the code from your remote

Self Latched Mode

Some call this self locked mode.  In this mode a press of the button switches the relay, another press of the same button reverses the switch of the relay.

1. Press the unit 2 times
2. Wait till the LED lights up
3. While the LED lights up send the code from your remote

Latched Mode

Some call this interlocked mode.  In this mode you will need to send two different codes, one code switches the relay, and the other code reverses the relay.

1. Press the unit 3 times
2. Wait till the LED lights up
3. Send the first code from your device, it will flash that it code the code
4. Wait will the LED lights up solid
5. Send the second code from your device.
