Get information from Deye Microinverter
The whole thing is just a learning exercise for now. We will see.
quickstart
overview
- clone the sources
- Bootstrap and create default user settings by just call
./cli.py edit-settings - Change the settings for your needs
- ...use the commands... ;)
- Setup systemd service to publish the inventer values to a Home Assistant instance via MQTT
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:
Usage: ./cli.py [OPTIONS] COMMAND [ARGS]...

Setup systemd services for Home Assistant
Update your settings via: ./cli.py edit-settings and insert MQTT credentials in section [mqtt]
Check also the config section [systemd] and [systemd.template_context]
but normally they must not be changed ;)
To verify your settings, call: ./cli.py debug-settings
To see the systemd service file content, just call: ./cli.py systemd-debug
Note: Some of the systemd commands, needs sudo because a normal user can't change systemd services!
You will see permission errors with a hint to call the cli with sudo ;)
If everything looks okay, setup and start the systemd service with: sudo ./cli.py systemd-setup
Check the services with: sudo ./cli.py systemd-status
most important commands
publish-loop
Help from ./cli.py print-values --help Looks like:
Usage: ./cli.py publish-loop [OPTIONS]
Publish current data via MQTT for Home Assistant (endless loop)
The "Daily Production" count will be cleared in the night, by set the current date time via
AT-command.

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

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

Example output of print-values call:
print-at-commands
Help from ./cli.py print-at-commands --help Looks like:
Usage: ./cli.py print-at-commands [OPTIONS] [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
Or specify one or more AT-commands, e.g.:
.../inverter-connect$ ./cli.py print-at-commands WEBVER .../inverter-connect$ ./cli.py
print-at-commands WEBVER WEBU
e.g.: Set NTP server, enable NTP and check the values:
.../inverter-connect$ ./cli.py print-at-commands 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 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] REGISTER LENGTH
Read register(s) from the inverter
e.g.: read 3 registers starting from 0x16:
.../inverter-connect$ ./cli.py read-register 0x16 3
e.g.: read the first 32 registers:
.../inverter-connect$ ./cli.py read-register 0 32
The start address can be pass as decimal number or as hex string, e.g.: 0x123
