enverproxy's Issues

Ported the code to Node-RED

Some nice thing i would like to share.

I had the Python-script running in Docker + a MQTT-container beside it for a few days and worked quite good. But it felt a bit 'bulky' for me as i don't use MQTT anywhere else. For monitoring my panels i had to run two containers. Most of my home automation stuff i do in Node-RED so i thought: why not try to port the code of this project to Node-RED.

I managed to do it 😄

You can find the JavaScript-code here: https://gathering.tweakers.net/forum/list_message/71502554#71502554
Backup link: https://gist.github.com/ThinkPadNL/4dd4e000d94d714a1b62f9ab9530d41e

The code is 'static', as in: you will have to define the inverters in the code by yourself. I used HexEd.it to work through the Enverbridge datapackets (sniffed by Wireshark). Using a forEach method would be nicer (as the inverter data is stored in the package at fixed distances) but as i am not a programmer this was quite complex for me. I only have a few panels, so searching the right bytes and defining them by hand in the script was OK for me.

This is not really a issue, so i will close it again, but i thought it would be nice to share it here. Maybe it is useful for someone.

Script crashing on receiving data

The script seems to crash with the message ValueError: invalid literal for int() with base 10: 'aa998a57'

How to run in Docker?

Most of my homelab stuff is running in Docker. I was trying to create a Docker image for this project, but so far i cannot get it running. This is the Dockerfile i made:

 FROM python:3.9-alpine
 RUN apk --no-cache add git
 RUN pip3 install paho-mqtt
 RUN git clone https://github.com/zivillian/enverproxy.git /data/app
 RUN ls -a /data/app
 RUN sed -i "s|/etc/enverproxy.conf|/data/app/enverproxy.conf|g" /data/app/enverproxy.py 
 WORKDIR /data/app
 EXPOSE 1898
 CMD ["./enverproxy.py"]
 ENTRYPOINT ["python3"]

The image builds succesfully, but when i try to run a container based on this image, i get this error:

 Traceback (most recent call last):
   File "/data/app/./enverproxy.py", line 309, in <module>
     server.connect_mqtt(config['enverproxy']['mqtthost'], config['enverproxy']['mqttuser'], config['enverproxy']['mqttpassword'],                          int(config['enverproxy']['mqttport']))
   File "/data/app/./enverproxy.py", line 69, in connect_mqtt
     self.mqtt.connect(host, port)
   File "/usr/local/lib/python3.9/site-packages/paho/mqtt/client.py", line 914, in connect
     return self.reconnect()
   File "/usr/local/lib/python3.9/site-packages/paho/mqtt/client.py", line 1044, in reconnect
     sock = self._create_socket_connection()
   File "/usr/local/lib/python3.9/site-packages/paho/mqtt/client.py", line 3685, in _create_socket_connection
     return socket.create_connection(addr, timeout=self._connect_timeout, source_address=source)
   File "/usr/local/lib/python3.9/socket.py", line 844, in create_connection
     raise err
   File "/usr/local/lib/python3.9/socket.py", line 832, in create_connection
     sock.connect(sa)
 OSError: [Errno 99] Address not available`

I have port 1898 exposed in the container.

Any ideas how to get this working in Docker?
