How to flash

  1. Open

    There are 6 triangle screws to open the box. Product outside

  2. Unmount circuit from the box

    6 more screws (classic ones) Product Inside

  3. Pins

    Pins are at the corner, near usb ports. Vcc is not 3V, it needs to be >4V. Product Inside Pins

Basic Config

The configuration has some default sensors for wifi reporting etc. There are LED's showing the state of each socked, but they are not settable through GPIO's, they just reflect the state of the socket directly.

substitutions:
device_name: shp9
# NO Powermeasurement
# BW-SHP9
# relay1 is set up as a lamp, and the button is controlling the relay1
# All relays can be controlled through Esphome/HA, but the button only controls relay1
# Wifi is set with static IP, and fast_connect is used as the SSID is hidden
# The Web server is active, and both web_server and OTA is protected by PW.

Advanced config additions

In the esphome section, you can perform actions when the device boots:

on_boot:
then:
# - switch.turn_on: relay1
- switch.turn_on: relay2
- switch.turn_on: relay3
- switch.turn_on: relay4

Under wifi this can be added, this will set up static IP, allow the device to connect to a hidden SSID (fast_connect) and create a backup AP

wifi:
reboot_timeout: 60min
manual_ip:
static_ip: 192.168.1.100
gateway: 192.168.1.1
subnet: 255.255.255.0
fast_connect: true
# Enable fallback hotspot (captive portal) in case wifi connection fails
ap:
ssid: "${device_name} Hotspot"
password: !secret appw

This wll activate the internal webserver with password protection

web_server:
port: 80
auth:
username: !secret webuser
password: !secret webpw

To set time locally to the same as on the HomeAssistant (better logging)

# Sets time from Homeassistant
time:
- platform: homeassistant
id: homeassistant_time

To have different data shown for the device (ESPHome version) and the wifi. Will appear as sensors in HA.

# Sensors for ESP version and WIFI information
text_sensor:
- platform: version
name: "${device_name} ESPHome Version"
- platform: wifi_info
ip_address:
name: "${device_name} ip"
ssid:
name: "${device_name} ssid"

This will create sensors so that you can track wifi coverage for the devices, and also note the uptime for the devices.
