Rename set commands to config correct json buffer size and gateway name replace state to cmd replace set by config add restart and erase command add unicity to gateway command switches BLE devices shouldn't be child of the gateway make the BTtoMQTT topic consistent with other definitions

# Actuators
|
|
## ON OFF
|
|
This module enables to actuate things by giving to a PIN a HIGH or LOW value corresponding to an MQTT topic.
|
|
Example usage: Connect a transistor to power a relay, connect a led...
|
|
|
|
So as to pilot the pin use the following commands with [simple receiving](../upload/pio.md#api):
|
|
|
|
OFF command:
|
|
`mosquitto_pub -t home/OpenMQTTGateway_MEGA/commands/MQTTtoONOFF/setOFF -m 15`
|
|
|
|
ON command
|
|
`mosquitto_pub -t home/OpenMQTTGateway_MEGA/commands/MQTTtoONOFF/setON -m 15`
|
|
|
|
or with [json receiving](../upload/pio.md#api)
|
|
|
|
OFF command:
|
|
`mosquitto_pub -t home/OpenMQTTGateway_MEGA/commands/MQTTtoONOFF -m '{"pin":15,"cmd":0}'`
|
|
|
|
ON command
|
|
`mosquitto_pub -t home/OpenMQTTGateway_MEGA/commands/MQTTtoONOFF -m '{"pin":15,"cmd":1}'`
|
|
|
|
## FASTLED
|
|
### The FASTLED module support 2 different operation modes
|
|
1. control one specific RGB LED
|
|
* Set color
|
|
* Set blink
|
|
|
|
2. Start fire animation (Fire2012)
|
|
|
|
### Hardware wiring
|
|
Theoreticaly it should be possible to use every free IO pin. But after some tests only pin D2 works at WEMOS D1. Other platforms can work.
|
|
The default setting use NEOPIXEL (WS2812B). The simplest wiring is direct connect D2 to data pin of LED stripe and connect VCC/GND to power source. You should also add an capacitor.
