Compatibility for HMS 3K-24V

[diybateriaslifepo4]

as we have talked about in the other issue to try to solve the problem with this model, problem is temperature and SBU not working

I've added an example response (extracted from your logs) to the parser: https://github.com/syssi/esphome-pipsolar/commit/9ea662c191a1ff3a50e81d4f3924073d559141a6

IMO the different fields & values doesn't align with your device. Could you try to ask the seller for some specs / protocol description? A description for every value/field would be awesome:

Pos.:    1     2     3    4     5   ...  
Values: 001.0 00.0 229.0 50.0 0000 0000 000 413 27.23 000 100 0672 0000 000.0 00.00 00001 10010000 00 04 00000 000

I bought it from an aliexpress seller, I have asked him for various things like firmware update and he does not offer any support. But I will try again, thank you.

I have tried this, but nothing has changed, the temperature is still wrong and the SBU mode can not be activated I leave you the current log in case you see something else.

One more thing, the equipment is without solar panels or 220v input connected, I have it on the test table connected to a power supply.

[diybateriaslifepo4]

I have just done a test, I have connected the inverter to the watchpower software, and I have activated the SBU mode, then I have connected it again to the esp8266 and it appears that it is in SBU mode correctly. I'll leave you the log for what it's worth:

so it appears to me as correctly activated, if I select another of the two modes it changes correctly, but I can no longer select SBU again.

[syssi]

Good job! Using watchpower is a good idea. It's possible to capture the command to switch the modes from watchtower? It looks like sensing the mode works fine but the command to change the mode is bogus.

I don't know how to do it, if you teach me I will do it 😅

@diybateriaslifepo4 Could you provide your yaml configuration?

I've found this issue: https://github.com/jblance/mpp-solar/issues/46

And this important detail:

Does your CRC generator work with the POP02 (battery output source priority)command? Mine gives E2 0A as the CRC but the box expects E2 0B. https://forums.aeva.asn.au/viewtopic.php?p=53712#p53712

We should increase the log level of the uart component. ESPHome will print every transmitted & received byte to the log. The important part is the POP02 request.

$ echo -n POP02 | hexdump -C
00000000  50 4f 50 30 32                                    |POP02|

We are looking for something like this:

50.4F.50.30.32.E2.0A
# or
50.4F.50.30.32.E2.0B

How to increase the log level:

logger:
  level: VERY_VERBOSE
  logs:
    uart: VERY_VERBOSE
    uart.arduino_esp8266: VERY_VERBOSE
    # Make some components less verbose
    api.service: WARN
    ota: WARN
