Blitzwolf BW-SHP9 Triple powerstrip with dual USB power

Blitzwolf BW-SHP9 Triple powerstrip with dual USB power

Device Type: plug
Electrical Standard: eu
Board: esp8266

Product image Product Measurements

Model reference: BW-SHP9

The powerstrip has four controllable relays, one for each socket, and one for the dual 2.4A usb power.

Manufacturer: BlitzWolf

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. To configure chip for flashing GPIO0 needs to be pulled down to ground at boot.

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.
