Hi, I have board with uart controlled. How in ESPHome I can make virtual switch with this? Can’t understand.
uart:
tx_pin: GPIO1
rx_pin: GPIO3
baud_rate: 115200
switch:
- platform: uart
id: turn_on
name: "Workspace light on"
data: [0xA0, 0x02, 0x01, 0xA3]
- platform: uart
id: turn_off
name: "Workspace light off"
data: [0xA0, 0x02, 0x00, 0xA2]
logger:
hardware_uart: UART1
light:
- platform: binary
name: Kitchen workspace
output:

Create a template switch and use the turn_on and turn_off action to write to the uart
https://esphome.io/components/switch/template.html
https://esphome.io/components/uart.html#uart-write-action
This will have to be an optimistic switch unless you have some way to get the switch state.
switch:
- platform: template
name: "Workspace light"
optimistic: true
turn_on_action:
- uart.write: [0xA0, 0x02, 0x01, 0xA3]
turn_off_action:
- uart.write: [0xA0, 0x02, 0x00, 0xA2]

I’m trying to control an Arduino nano in order to drive some gpio through serial commands but it doesn’t work … probably my Arduino code is not correct … is it possible to have an example of Arduino sketch to be controlled by ESPHOME?

Works perfekt with LC Tech ESP8266 RELAY
