Blitzwolf BW-SHP6 Socket with powermonitoring

Blitzwolf BW-SHP6 Socket with powermonitoring

General Notes

Model reference: BW-SHP6

Manufacturer: BlitzWolf

There are two versions of this plug, a 10A version and a 15A version. The pinout seems to be the same.

Basic Config

The configuration has some default sensors for wifi reporting, etc.

substitutions:
device_name: shp6
# Higher value gives lower watt readout
current_res: "0.00290"
# Lower value gives lower voltage readout
voltage_div: "940"
# Max Power is 3450W for 15A and 2300W for 10A
max_power: "3450"
# 2020 model uses GPIO4 for CF1
cf1_pin: GPIO14
# BW-SHP6, outlet with powermonitoring.
# One button for the relay, and one red led for the 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

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 will 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

Send a notification to Home Assistant when max power is exceeded.

sensor:
- platform: hlw8012
---
power:
name: "${device_name} Power"
unit_of_measurement: "W"
id: power
icon: mdi:flash-outline
on_value_range:
- above: ${max_power}
then:
- output.turn_off: led
- switch.turn_off: relay
- homeassistant.service:
service: persistent_notification.create
data:
title: Message from ${device_name}
data_template:
message: Switch turned off because power exceeded ${max_power}W

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.

update_interval: 60s
