# 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
|
|
1. total of 4 relays, relay 2 will be toggled: `http://[device-ip]/relays?toggle=0,1,0,0`
|
|
2. total of 3 relays, relay 1&3 will be switched on: `http://[device-ip]/relays?switch=1,0,1`
|
|
|
|
## JSON API
|
|
You can switch relay state using the following JSON object transmitted to: `http://[device-ip]/json`
|
|
|
|
|
|
Switch relay 0 on: `{"MultiRelay":{"relay":0,"on":true}}`
|
|
|
|
Switch relay4 3 & 4 off: `{"MultiRelay":[{"relay":2,"on":false},{"relay":3,"on":false}]}`
|
|
|
|
## 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
|
|
|
|
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.
|
|
|
|
* `enabled` - enable/disable usermod
|
|
* `pin` - GPIO pin where relay is attached to ESP
|
|
* `delay-s` - delay in seconds after on/off command is received
|
|
* `active-high` - toggle high/low activation of relay (can be used to reverse relay states)
|
|
* `external` - if enabled WLED does not control relay, it can only be triggered by external command (MQTT, HTTP, JSON or button)
|
|
* `button` - button (from LED Settings) that controls this relay
|
|
|
|
If there is no MultiRelay section, just save current configuration and re-open Usermods settings page.
