🐛 Firmware version 1.0 bug

In station's firmware 1.0 is a bug preventing data to be sent to Home Assistant.

This might be a problem even on firmwares > 1.0.

🤔 The issue

Once you have set an URL in station with port as url:port, the bug will cause that data will not be sent to the Home Station at all.

station port

If you ommit the :port, station will send data to designated port :80 of your URL.

🩹 Workaround

💡 There is a solution to this!

You have to redirect incoming data on port 80 from station's IP address to port 8123 or what ever port your instance of Home Assistant is running. To achive this, you have to run iptables to redirect ports.

Eg. 192.168.1.2.:any (station) -> 192.168:1.1:80 ---> 192.168.1.1:8123 (HA)

So I provide a script that will handle this bug. But you must run this script every time you restarted Home Assistant, because iptables will not remain on reboot.

Ok, now how to do it?

Step one

Install Advanced SSH & Web Terminal from add-ons. Yes, it has to be Advanced SSH & Web Terminal not regular Terminal & SSH, as regular Terminal & SSH do not have such functions, capabilities and privileges.

Step two

After you have installed Advanced SSH & Web Terminal configure it to run on some free port (eg. 23). Make sure you have configured username and authorized_keys. Please be advised, that this script will not work with password.

ssh_addon_setup

Step three

Open Web Terminal. Copy and paste this command:

bash <(wget -q -O - https://raw.githubusercontent.com/schizza/SWS-12500-custom-component/main/install_iptables.sh)

This will download and run installation script of this workaround. Follow the instructions in the script.

You will be asked for:

  • your station's IP
  • Home Assistant IP
  • Home Assistatn port
  • username in SSH addon (this is one you setup upon installation of the addon)
  • SSH port (also one you setup with the addon)

ssh_run

The scritp will set all you need to modify iptables on every Home Assistant start.

⚠️ Scrip will modify configuration.yaml and automations.yaml so, please look at it and check that it does not contain any error.

If you have already set shell_command in your configuration.yaml then you have to transfer created one to your already set one.

Step four

Script files are stored in your config/iptables_redirect directory. There is also your public key for your SSH server configuration in ssh directory. It is important to add public key to your SSH server configuration.

So you are no all set! 🎉
