I created a flow to collect data from a S1155 heat pump. I only added a few nodes, but after a short period of time exceptions started to appear. The data stoped being collected. Restarting the flow helps for a short time, but right away the exceptions start appearing again.

So I understand that it's working fine for an amount of time. Do you have a stable network connection to your heatpump? Does it recover after some time?

[pklopotowski]

yes, it works fine for a while. The connection is stable, the heat pump is directly connected to the network via Ethernet. To give you a complete picture, Home Assistant is also connected to the same heat pump and get data without any problems. I use Home Assistant to preview current state of the pump and I want to use Node Red to collect historical data. And regarding connection recovery => no, the connection is not restored.

[andrei-tatar]

I also had a look at my system. It seems mDNS is not working anymore, since the latest NIBE firmware update and the nodes weren't even showing the error. Will update the logic a bit

[andrei-tatar]

@pklopotowski I pushed an update. Let me know if it works better now.

[pklopotowski]

where did you publish the release? Is there any change to update here: https://flows.nodered.org/node/@andrei-tatar/node-red-contrib-nibetcp

[andrei-tatar]

Ah, of course I always forget to update that. Done now.

[pklopotowski]

thx, update applied, will back to you with the results

[pklopotowski]

no errors, thx a lot.
