core: [Errno 104] Connection reset by peer and [Errno 111] Connect call failed after updating heat pump to 2.22.6

The problem

After updating the S1255 heat pump to software version 2.22.6 the integration is unable to fetch all information from the heat pump. I can see in the dashboard that the integration starts to fetch information but before all registers is read the integration throws the errors below. I suspect it may be because Nibe added new Modbus TCP/IP registers?

https://www.nibe.eu/webdav/files/myuplink_changelog/nibe-n.pdf

Added Modbus TCP/IP registers to read shunt voltage for extra climatesystem 2-8
- Climatesystem 2 = 2401
- Climatesystem 3 = 2402
- Climatesystem 4 = 2403
- Climatesystem 5 = 2404
- Climatesystem 6 = 2405
- Climatesystem 7 = 2406
- Climatesystem 8 = 2407

Added RPP10 to holiday functionality

Added possibility to add hourly prices in menu and by Modbus TCP/IP for shunted addition in Smart
Energy Source

Added extended ventilation settings on home screen and RMU S40

Added power consumption for S135 in energy log

It does not look at entitles during setup, so does not matter which is enabled. You likely need to restart your pump.

How to roll-back to previous Firmware on S1255PC6: 1. shutdown the device until Power Button is blue 2. Power on the device 3. when the light of the power button gets white, press the button as long as it gets green and release it (one time this failed and the machine powered off, so I successfully retried it one time by pressing the button only a second) 4. the device starts with backup firmware I hope that helps you as well…
