This is a USB connection that works in series like old USB modems…
On a Linux with picocom we get the clamp measurement.
picocom -b 19200 /dev/ttyACM0
then @ to read the value
5.2
5.4 at each @ on the keyboard.
I added this config
sensor:
- platform: serial
serial_port: /dev/ttyACM0
name: UsbPower8870
baudrate: 19200
But the entity remains empty. It is necessary to send the read request carried out by the @ command and there I will not be able to indicate this in the config.
The serial doc :
talks about template but not about placing a command.
If you had any info?
Maybe I’m not using the right method to integrate this material.
