Extra battery to another device

[vwt12eh8]

The serial number is used to manage the extra battery as a single device.

This avoids the problem of multiple entities even if they are shared by multiple units.

Issue

The following devices can have multiple extra batteries connected to them and I don't know how to get the serial number for each one.

• DELTA max
• DELTA pro

We are looking for someone who has these devices and two extra batteries and can work with us to find a way to solve this.

I have 2 DPs and each has 2 EB, both are in this solution already, how can I assist?

@GCustom Thank you.

Later, we will publish a special branch that will parse the received data and include it in the diagnostic information, so please report back with the results of how that works.
We will let you know again when it is ready.

[vwt12eh8]

A branch with additional diagnostic codes is now available.
If you would like to help, please try the following and provide diagnostic information as a result.
https://github.com/vwt12eh8/hassio-ecoflow/tree/serial-diagnostics

Warning.

• This includes debugging code, so the load is larger than the normal version. Please do not use it regularly.
• The diagnostic information will get the serial number of the device. If you put it here, you will be disclosing the serial number. If you are concerned about this, please try another method of transmission. The serial number will be used only for data analysis and will be destroyed as soon as it is completed.

Hi @vwt12eh8 - I've done this on my Delta Pro with 2 extra batteries and have the diagnostic information.

I've created a private repository and invited you as a collaborator. I will upload the diagnostic code there.

[vwt12eh8]

@lwsrbrts Thanks for providing the data.

As far as I checked, it seems that only one of the batteries was notifying the serial number.

If possible, could you also try the pattern of connecting the extra battery to port 2 only?

As a side note, I've heard before that you need to connect to port 1 to do FW updates on the extra battery. Maybe port 2 has restricted communication...

Yes, I noticed that there was only one result.

I'll disconnect the battery from port 1 and post the result. Hopefully that's what you're asking.

As a side note, I've heard before that you need to connect to port 1 to do FW updates on the extra battery. Maybe port 2 has restricted communication...

Correct. You do have to swap the battery on port 2 over to port 1 to get its firmware to update.

I'll post the updated export data in a few minutes on the repo. < Done

I still can't seem to get any info on the battery on port 2...

It seems to be difficult to manage devices by serial number...

If there's anything else I can help with, please let me know.
