Zentec Smart Plug

Zentec Smart Plug

Standard plug socket, with 2A USB port. Flashable via tuya-convert. Purchased from Amazon.

At least two versions of this plug exist, but the only difference between the two is the pull-up on the pin for the button.

Split Configuration

If you have multiple of these sockets (likely since they come in packs), you may want to keep the shared code in one file and only put device specific information in files for each relay.

zentec-common.yaml:

esphome:
name: ${device_name}
platform: ESP8266
board: esp01_1m
wifi:
ssid: !secret wifissid
password: !secret wifipass
fast_connect: on #we only have one WiFi AP so just use the first one that matches
ap: #since we listed an SSID above, this AP mode will only enable if no WiFi connection could be made
ssid: ${friendly_name}_AP
password: !secret wifipass
# Enable logging
logger:
baud_rate: 0 #disable UART logging since we aren't connected to GPIO1 TX
# Enable Home Assistant API
api:
# Enable OTA updates
ota:
safe_mode: True
# Enable web server
web_server:
port: 80
binary_sensor:
- platform: gpio
pin:
number: GPIO13
#mode: INPUT_PULLUP # only needed on older versions of this plug
inverted: True
name: "${friendly_name} Button"
internal: false # set to true to hide from hub
on_click:
- switch.toggle: relay
status_led:
pin:
number: GPIO02
inverted: true
switch:
- platform: gpio
name: "${friendly_name}"
id: "relay"
pin: GPIO12
on_turn_on:
then:
- switch.turn_off: "redLED"
on_turn_off:
then:
- switch.turn_on: "redLED"
restore_mode: ALWAYS_OFF
- platform: gpio
name: "redLED"
id: "redLED"
pin: GPIO4
inverted: true
restore_mode: ALWAYS_ON
internal: true

And for each device's yaml:

substitutions:
device_name: zentec
friendly_name: Zentec Plug
