Validation Error: Timeout on Writing to Nibe Heat Pump During Configuration #120023
Comments
Hey there @elupus, mind taking a look at this issue as it has been labeled with an integration ( Code owner commandsCode owners of
(message by CodeOwnersMention) nibe_heatpump documentation |
Are you using the lilygo t-can485 board? |
Actually. The pump looks to actually be responding to the request. It rejecting it. That might actually be a valid response. Either that or we have the wrong parameter number for that pump. |
Which exact model heat pump is it? |
Are you using the LilyGO T-CAN485 board? Which revision of it? Do you have any firewalls or routers between the devices? Which exact model heat pump is it? Or is it because i updated on the 04.06.2024 to the new software Version: 9699R4 from the Heatpump? |
Ok. Lets try something weird.. :). Go into the extra settings on the pump and enable the RMU40 accessory. This should cause your pump to go into alarm. Dont clear it, but try to add the system in HA while the pump is showing an alarm on screen. This might work, if the pump is rejecting the write request to clear alarms when there are none. Worth a shot. The you can disable the RMU40 accessory again and clear any alarms. |
As I was writing this, I reset the Nibe back to software version 9443R7. Guess what, that fixed it! However, Nibe wanted me to upgrade because of the change from Nibe Uplink to MyUplink. I thought they wouldn't touch the Modbus, but reverting the software made it pass on the first try. I've now been working on it for 2 days 😄 Do you know if Nibe changed something with the modbus with the shift to MyUplink? I didn't read anything in the changelog. ---old text--- |
Oh! So they changed some behavior there. I was afraid they might. Crap i need to take the time and update my pump and see what others stuff they might have broken. |
The problem
Bug Description for Nibe F1255
When attempting to configure the Nibe heat pump, a validation error occurs. The error happens during the connectivity check and results in a FieldError.
Steps to Reproduce
Expected Behavior
The configuration should be validated and saved successfully without triggering a WriteException.
Actual Behavior
The validation fails, and a WriteException with the message "Heatpump denied writing alarm-reset-45171" is triggered, followed by a FieldError.
Additional Information
Home Assistant Version: 2024.6.3
Nibe Integration Version: newest
I checked that general UDP packets arrive at Home Assistant via nc -tpl 19999 (I can see the name of the heat pump, so the communication from the ESP and the heat pump should be working?) and also checked that the port was bound when the setup started. It has already been tested that the UDP packets are received back on port 19999, and packets are indeed reported back at that port.
What version of Home Assistant Core has the issue?
2024.6.3
What was the last working version of Home Assistant Core?
No response
What type of installation are you running?
Home Assistant OS
