inverter

Get information from Deye Microinverter

The whole thing is just a learning exercise for now. We will see.

quickstart

Currently just clone the project and just start the cli (that will create a virtualenv and installs every dependencies)

Note: Please enable https://www.piwheels.org/ if you are on a Raspberry Pi !

e.g.:

~$ git clone https://github.com/jedie/inverter-connect.git
~$ cd inverter-connect
~/inverter-connect$ ./cli.py --help

The output of ./cli.py --help looks like:

print-values

Help from ./cli.py print-values --help Looks like:

Usage: ./cli.py print-values [OPTIONS] IP

 Print all known register values from Inverter, e.g.:
 .../inverter-connect$ ./cli.py print-values 192.168.123.456

╭─ Options ────────────────────────────────────────────────────────────────────────────────────────╮

print-at-commands

Help from ./cli.py print-at-commands --help Looks like:

Usage: ./cli.py print-at-commands [OPTIONS] IP [COMMANDS]...

 Print one or more AT command values from Inverter.
 Use all known AT commands, if no one is given, e.g.:
 .../inverter-connect$ ./cli.py print-at-commands 192.168.123.456
 Or specify one or more AT-commands, e.g.:
 .../inverter-connect$ ./cli.py print-at-commands 192.168.123.456 WEBVER .../inverter-connect$
 ./cli.py print-at-commands 192.168.123.456 WEBVER WEBU
 e.g.: Set NTP server, enable NTP and check the values:
 .../inverter-connect$ ./cli.py print-at-commands 192.168.123.456 NTPSER=192.168.1.1 NTPEN=on
 NTPSER NTPEN
 wait a while and request the current date time:
 .../inverter-connect$ ./cli.py print-at-commands 192.168.123.456 NTPTM
 (Note: The prefix "AT+" will be added to every command)

read-register

Help from ./cli.py read-register --help Looks like:

Usage: ./cli.py read-register [OPTIONS] IP REGISTER LENGTH

 Read register(s) from the inverter
 e.g.: read 3 registers starting from 0x16:
 .../inverter-connect$ ./cli.py read-register 192.168.123.456 0x16 3
 e.g.: read the first 32 registers:
 .../inverter-connect$ ./cli.py read-register 192.168.123.456 0 32
 The start address can be pass as decimal number or as hex string, e.g.: 0x123

start development

For development, we have a separate CLI, just call it:

~/inverter-connect$ ./dev-cli.py --help

The output of ./dev-cli.py --help looks like:
