Unexpected error fetching Nibe Heat Pump data

[m-wo]

The problem

Lately, not sure if related to a HA update but I haven‘t read any changes in the changelogs, I have trouble with my Nibe Heat Pump integration that cannot read data anymore via modbus tcp. Double checked connectivity and everything, device is up2date as well.

Error from the logs:

Start be rebooting the heatpump and disabling all entities in HA. The new firmwares are known for having several crashing bugs on modbus.

Then enable entities a few at a time.

[Shuties]

I have the same issue, the heatpump becomes unavailable after some time, and randomly it pops back up. maybe once every other day. Rebooting the heatpump and disabling all entities in HA cannot be a long term solution? If i'm away i would ofcourse like to monitor my heatpump, and this makes it impossible. Is it problem in the NIBE firmware or the integration? Using a S1256 with version 2.27.5

Logbook looks the same as OP's. Latest HA versions installed on home assistant green.

[elupus]

There is problems with firmware on the pumps. We should not be able to crash them by reading parameters from them. Even if we did do something wrong, they should not crash like they do.

Sometimes its an soft crash, where they become unresponsive over modbus. Sometimes they just crash hard and reboot.

One you figure out which entries crash the pumps, it should be reported ro nibe.

[Shuties]

So, i should try restarting, with all entities disabled, and then enable one by one until i find out which one makes it crash? Have i understood it correctly?

[elupus]

Yup

[m-wo]

I've followed your advice and disabled most of the entities, I'm not down to the absolute minimum that are required for automation and I'm still getting the errors. Even if I'd go and disable the last entities, I'd still be dependent on them. How would I report them to Nibe then?

[elupus]

Ignore your automations too start with. We need to find the entity that isn't working.

[Shuties]

I have not had the problem again since i updated the software to a new release since a week ago. Just wanted to let you know. 3.0.10 is the version im running, and no problems in a whole week.

[philippe-tc]

I'm havoing the same kind of problems since updating my Nibe S1255 to software version 3.0.10. The error log of my HA (core 2024.5.5 and OS 12.2) says:

[elupus]

Your pump has either crashed or you have not enabled modbus. Restart it and check that modbus is enabled.

[m-wo]

v3.1.7 has been released - not much about Modbus fixes but I hope this solves it.

[elupus]

We can't do much about this. The pump need to be restarted.
