This is a PlatformIO project.

Firmware Reset

  1. Power on the WiFi Socket (plug in)
  2. Press down and hold the Power-Button during the first 5s
  3. Release Power-Button when the WiFi LED starts rapidly fast blinking
  4. The firmware reset ends after about 30s indicated by a permanent WiFi LED on.

Default Settings

After a firmware reset the following values are set.

OpenHAB - HTTP Binding sample

Switch LivingRoom_Power "Living Room Outlet" {http=">[ON:GET:http://wifi-socket.ip/on] >[OFF:GET:http://wifi-socket.ip/off]"}

If you like to read the state of the socket by OpenHAB. First create a file getState.js in the transform directory with the following content:

JSON.parse(input).state;

add

<[http://wifi-socket.ip/state:30000:JS(getState.js)]

to the Switch definition. Every 30s the state of the socket will be checked.

OpenHAB - MQTT binding sample for the switch and the energy monitor values

MQTT Binding Version 1.x

Switch WifiSocketBwShp6 "BW SHP6 Ein / Aus" {mqtt=">[mosquitto:socket-bw/in:command:ON:1],>[mosquitto:socket-bw/in:command:OFF:0],<[mosquitto:socket-bw/out:state:default]"}

Number WifiSocketBwShp6Voltage "BW SHP6 Voltage [%.1fV]" {mqtt="<[mosquitto:socket-bw/voltage:state:default]"}

Number WifiSocketBwShp6Current "BW SHP6 Current [%.2fA]" {mqtt="<[mosquitto:socket-bw/current:state:default]"}

Number WifiSocketBwShp6Power "BW SHP6 Power [%.1fW]" {mqtt="<[mosquitto:socket-bw/power:state:default]"}

MQTT Binding Version 2.x

For the Binding Version 2.x it is necessary to configure the MQTT Thing and according to that the items.

mqtt.things:

Bridge mqtt:broker:mosquitto "Mosquitto" [ host="127.0.0.1", secure=false, clientID="MotherShip", username="$MQTT_USERNAME", password="$MQTT_PASSWORD"]
{
   Thing topic socket-bw "BW SHP6" {
    Channels:
     Type switch : state "BW SHP6 Ein / Aus" [ stateTopic="wsocket-bw/out", on="ON", off="OFF", commandTopic="socket-bw/in", on="ON", off="OFF" ]
     Type string : voltage [ stateTopic="wsocket-bw/voltage" ]
     Type string : current [ stateTopic="wsocket-bw/current" ]
     Type string : power [ stateTopic="wsocket-bw/power" ]
   }

}

mqtt.items:

Switch WifiSocketBwShp6 "BW SHP6 Ein / Aus" { channel="mqtt:topic:mosquitto:socket-bw:state" }

Number WifiSocketBwShp6Voltage "BW SHP6 Voltage [%.1fV]" { channel="mqtt:topic:mosquitto:socket-bw:voltage" }

Number WifiSocketBwShp6Current "BW SHP6 Current [%.2fA]" { channel="mqtt:topic:mosquitto:socket-bw:current" }

Number WifiSocketBwShp6Power "BW SHP6 Power [%.1fW]" { channel="mqtt:topic:mosquitto:socket-bw:power" }
