Detection of MPPT trackers switches between settings and solarcharger upon reboot

[AminShAT]

Hi,

sometimes I need to reconfigure my MPPT trackers after reboot, because they are not found at the right device anymore. It looks a bit like, the device that is detected first gets the trackers assigned.

Hi @sfstar. Were you able to look at that already?

I am reluctant to install the new HA core update, because I do not want to have change all config again after a reboot.

BTW: what just comes to my mind: might this also depend on the time of day, you do the reboot, e.g. if the MPPT is on during sunshine hours or off during the night?

Any news on this @sfstar?

Hello AminShAT and thank you for opening this issue,

This is an older present issue going back to #47.
It requires more investigation before an solution can be implemented.
Could you perhaps verify your theorie regarding the available when the device is not producing energy?

[AminShAT]

Hi,

Will do so, you mentioned version 0.2 available already, right? In HA I still get pointed to the 0.1.7 release. Anything I need to do?

[AminShAT]

Hello,

Can not confirm my theory. Currently all parameters remain with the settings device regardless, if I restart during night or day times.

Update:

I found out, that the rescan and startup sequence behave differently:

rescan assigns the parameters to the MPPT-loader.
restart assigns the parameters to Settings.

I did a rescan this morning for the 4th inverter and got the parameters misassigned to the MPPT. After the update and reboot this evening, everything was fine. So I did a rescan again and saw the same issue as this morning. A reboot fixed it again for me. So the phenomenon should be reproducible.

Thank you for this insightfull finding.
Could you perhaps share your integrations stored config from the .storage directory?

[AminShAT]

Happy to help, but can you tell me, which file you need exactly?

[sfstar]

Thank you @AminShAT,

My apologies for my late reply.
The config should be located in the core.config_entries file and should look something like this:

[AminShAT]

The content is actually quite large. Do you need certain parts?

[sfstar]

Only the json part for the victron integration.
You can recognize it with the "domain": "victron" part and select the data between the entry_id line above the domain part until the disabled_by line.
It will help me by providing me with a config that allows for the reproduction of your startup behaviour in my local test environment.

Thank you for your help. If you need any additional info about my Victron system, let me know.

Thank you for the config.
I believe I've found the source of the difference in behaviour between the rescan and restart logic.
Would you be able to screenshot the devices screen after a rescan and after a reboot in order to confirm? (Where the unit IDs are visible)

[sfstar]
