- Build wireless P1 interface
- Setup ESP with ESPEASY
- Setup Domoticz
Smart meter P1 WiFi gateway
According the following schematic from Tasmota
Build a shield to adapt the P1 5V signal to inverted 3.3V (ESP)
Below is also an interface as shield.
Setup ESP with ESPEASY
Setup the ESP with a device as P1 interface
Setup Domoticz
As shield
Shield for a Wemos D1 mini (Not tested yet)
Smart meter with optical interface

Serialsettings
- Baud rate 300
- Number of bits 7
- Parity E
- Number of stop bits 1
xonxoff=0 rtscts=0 timeout=20
Test connection
- Open terminal (Linux) and give the following commands
- stty -F /dev/ttyUSB0 300 -parodd cs7 -cstopb parenb -ixoff -crtscts -hupcl -ixon -opost -onlcr -isig -icanon -iexten -echo -echoe -echoctl -echoke
- cat /dev/ttyUSB0
- Open a second terminal and give the following commands
- echo -n -e ‘\x2F\x3F\x21\x0D\x0A’ > /dev/ttyUSB0
- At the first terminal you see meter identification
- ——————————–
- echo -n -e ‘\x2F\x3F\x21\x0D\x0A’ > /dev/ttyUSB0 && echo -n -e ‘\x06\x30\x30\x30\x0D\x0A’ > /dev/ttyUSB0 ( && commands must be given directly after each other)
- At the first terminal you see metered data
