KenwoodIOT

A simple project that works with the XS8/SL16 bus to address Kenwood products.

In addition, a transducer is built in to switch on the amplifier when a load is switched on at the socket.

Device Topology:

graph LR
    Kenwood(Kenwood XS8 / SL16) <--> ESP8266
    Telnet <--> ESP8266
    ESP8266 --> Relais(Relais)
    ESP8266 <--> MQTT(MQTT / HomeAssistant)
    ESP8266 <--- Current(Current Transformer)

Device Schematic:

Telnet:

The Device features a Telnet Server for Debugging Serial Prints over WiFi/Ethernet.

Telnet Commands:

/help
/reset
/clear
/bye
/info
/send

Setting Up:

First Setup:

Sensor Calibration:

Since I didn't have time to calibrate the sensor properly, I just took a 60W light bulb and used that as a reference.

The accuracy is not important in this project, because I don't use the real voltage, instead I use the static factor of 230 (V).
