FermenterAutoRestart after reboot/restart cbpi

[daGrumpf-bxp]

Hi, I've developed a small plugin to address a missing feature I needed for my own setup.

After a service restart or reboot (power loss, etc.), I wanted my fermenters to have their auto state automatically restored. By default, cbpi4 disables auto mode regardless of what the previous state was.

You can find the plugin here: https://github.com/daGrumpf-bxp/cbpi4-FermenterAutoRestart/

How it works:

• Every 10 seconds, the plugin monitors the auto state (on/off) of each fermenter and saves it to a fermenter_auto_state.json file in the cbpi4 config folder.
• On startup, the plugin waits 20 seconds for cbpi4 to finish loading all its components, then reads this file and restores auto mode for each fermenter that meets both conditions:
  1. had auto mode active before the reboot, and
  2. has the AutoResumeStateAfterReboot property set to Yes in its hardware settings.

Not sure what's missing. Exactly this function is already incorporated in the existing Fermenter logic and described in the documentation.

As for Autostart: if I understand the documentation correctly, it requires a fermenter recipe with steps to be configured.
I never use steps on my setup — I set my targets directly in the GUI whenever I want to change them, and start or stop auto mode from there.
In that case, Autostart doesn't actually restore anything if auto mode was only set through the GUI.
My plugin simply saves the auto state and restores it after a reboot or restart, regardless of any other configuration — no steps, no recipe needed.
It just brings auto back on if it was on before the restart.
