	Multi Relay
This usermod-v2 modification allows the connection of multiple relays each with individual delay and on/off mode.
HTTP API
All responses are returned as JSON.
Status Request: http://[device-ip]/relays
Switch Command: http://[device-ip]/relays?switch=1,0,1,1
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.
Toggle Command: http://[device-ip]/relays?toggle=1,0,1,1
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
- 4 relays at all, relay 2 will be toggled: 
http://[device-ip]/relays?toggle=0,1,0,0 - 3 relays at all, relay 1&3 will be switched on: 
http://[device-ip]/relays?switch=1,0,1 
MQTT API
wled/deviceMAC/relay/0/command on|off|toggle wled/deviceMAC/relay/1/command on|off|toggle
When relay is switched it will publish a message:
wled/deviceMAC/relay/0 on|off
Usermod installation
- Register the usermod by adding 
#include "../usermods/multi_relay/usermod_multi_relay.h"at the top andusermods.add(new MultiRelay());at the bottom ofusermods_list.cpp. or - Use 
#define USERMOD_MULTI_RELAYin wled.h or-D USERMOD_MULTI_RELAYin your platformio.ini 
You can override the default maximum number (4) of relays by defining MULTI_RELAY_MAX_RELAYS.
Example usermods_list.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.
