Basic Config

The configuration has some default sensors for wifi reporting etc.

substitutions:
device_name: shp7
# Higher value gives lower watt readout
current_res: '0.002291'
# Lower value gives lower voltage readout
voltage_div: '940'
# BW-SHP7, dual outlet with powermonitoring.
# One button for each relay, and one red led for each relay, as well as a blue status led
# Static IP is configured, and fast_connect is enabled, as the SSID is hidden
# Webserver is active and pw protected, and the OTA is password protected

Advanced config additions

Starting with ESPHome v1.16.1 the hlw8012 platform sensor now supports energy, so we can add the following to the hlw8012 platform sensor and get rid of the total_daily_energy platform sensor and the homeassistant time sensor:

sensor:
- platform: hlw8012
energy:
name: "${device_name} Energy"
unit_of_measurement: "Wh"
icon: mdi:flash-outline

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

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

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.

sensors:
- platform: wifi_signal
name: '${device_name} WiFi Signal'
update_interval: 60s
accuracy_decimals: 0
- platform: uptime
name: '${device_name} Uptime'
unit_of_measurement: days
update_interval: 300s
accuracy_decimals: 1
filters:
- multiply: 0.000011574

Some SHP7 devices experiences unexpected reboots after few minutes from start. Adding this sensor fixes the issue:
