IP67 readout interpretation

Hi @thiemovanengelen,
I need again your help.
Trying to understand how the IP67 data are saved and how to interpret.
I get the advertising data/values 0600650500FFFFFFFFFFFFFFFF in binary this would be
00000110 00000000 01100101 00000101 00000000 11111111 11111111 11111111 11111111 11111111

The first 8 bit are the Device state and the next 8 bit Charge error - ok no problem so far (00000110 00000000).

The next 13 bits are Battery voltage 1 and after the 11 next bits are the Battery current 1 →
01100101 00000101 00000000

Are the data again stored in little endian style / looks like to me?
I see from the Extra manufacturer Data that there is data available like Battery voltage 2 and 3.

I guess this is not relevant for IP67 chargers at all, right?

Thanks a lot for you awesome help.

Hi @Saschakopp

Yes. This is the case for all instant readout records / fields.

So the Battery voltage in this case is 00101_01100101 which is 1381, so this would mean 13.81V. The battery current is 00000000_000 which is 0, so this would mean 0.0A. And this makes sense for battery in storage mode (Device State = 6)

This is indeed not relevant for the IP67 chargers, but the same record layout is also used for the 3 output IP43 chargers.

With kind regards,

@thiemovanengelen thanks for the quick answer.
Is the IP67 supporting Temperature and AC current?

Hi,

Given that the instant readout data contains the invalid value for these fields, I would say it is not supported by the IP67 charger.

Kind regards,
