Nibe integration S1255 problems

HansKatsman commented 1 year ago

The problem

When adding the S1255 heat pump it will report back as S1155 with sensors

adding the current power makes the integration stop and unavailable Logger: homeassistant.components.nibe_heatpump Source: helpers/update_coordinator.py:201 Integration: Nibe Heat Pump (documentation, issues) First occurred: 10 december 2022 21:20:27 (5 occurrences) Last logged: 09:26:40

When you request over modbus, do you request two registers or one? Its a 32bit value according to our database.

HansKatsman commented 1 year ago

Hi,

This is a part of my modbus configuration to my Nibe S1255

The yellow part is the overall power usage I receive and it has a INT16 type

Let me know if you need additional information

You are reading it as int16. Docs say int32. Can you see if you get same failure of you request int32?

HansKatsman commented 1 year ago

Hi

I changed to int 32 and it did not give an error in logging

However the reading was suddenly very high

Before it gave 742 W and after the change I had 655.360 W

I changed it back to Int16 for modbus for proper history

You seen to have enabled the wrong entity? 32167 would match your modbus config.

dkmh commented 1 year ago

These are 2 different things: "32177" is the currently availabe PV Solar power if EME or Sunspec is used "32167" is the current power consumption of the heatpump <-- most propably this is what you want

But I can confirm that "current-power-eme-20-32177" seems to make problems since the last software update on my S1255, they seem to have changed something there. Will check the new register export when I'm at home.

HansKatsman commented 1 year ago

Yes the 32167 is the right one which I overlooked when selecting the data from your Nibe integration.

Now it’s working fine with the right data

Thanks

Hans Katsman

selecting 32167 solved the crash problem Thanks for your support
