The number of numbers behind the switch parameter must correspond to the number of relays. The number 1 switches the relay on. The number 0 switches the relay off.
The number of numbers behind the parameter switch must correspond to the number of relays. The number 1 causes a toggling of the relay. The number 0 leaves the state of the device.
Examples
1. 4 relays at all, relay 2 will be toggled: `http://[device-ip]/relays?toggle=0,1,0,0`
2. 3 relays at all, relay 1&3 will be switched on: `http://[device-ip]/relays?switch=1,0,1`
1. Register the usermod by adding `#include "../usermods/multi_relay/usermod_multi_relay.h"` at the top and `usermods.add(new MultiRelay());` at the bottom of `usermods_list.cpp`.
or
2. Use `#define USERMOD_MULTI_RELAY` in wled.h or `-D USERMOD_MULTI_RELAY`in your platformio.ini
You can override the default maximum number (4) of relays by defining MULTI_RELAY_MAX_RELAYS.
Example **usermods_list.cpp**:
```cpp
#include "wled.h"
/*
* Register your v2 usermods here!
* (for v1 usermods using just usermod.cpp, you can ignore this file)
*/
/*
* Add/uncomment your usermod filename here (and once more below)
* || || ||
* \/ \/ \/
*/
//#include "usermod_v2_example.h"
//#include "usermod_temperature.h"
#include "../usermods/usermod_multi_relay.h"
void registerUsermods()
{
/*
* Add your usermod class name here
* || || ||
* \/ \/ \/
*/
//usermods.add(new MyExampleUsermod());
//usermods.add(new UsermodTemperature());
usermods.add(new MultiRelay());
}
```
## Configuration
Usermod can be configured in Usermods settings page.
If there is no MultiRelay section, just save current configuration and re-open Usermods settings page.
