Disconnected nodes issue

Third party integrations Node-RED
1

I have a few nodes that do the following:
Read the temp from the Solis inverter, then compare this temp with a preset temperature and if it’s too hot turn on a switch (fan) and then it’s cooled… turn off the fan.

I also have a “tolerance” input… to give me a variable temperature tolerance so the fan doesn’t go on and back off again.
eg: if it’s 40C then don’t turn on fan until it reaches 41C and then turn off when at 39C.

This works ewll when Node-Red behaves… but recently I’m seeing the nodes show “disconnected” in NR.
But in HA the sensors are fine…

Any ideas what’s going on… is NR losing connection to HA ?
Target Temp and Temp tolerance are “helpers” in HA.

I found that restarting the flows resolves the issue for a little while… then disconnected again.

4

Any update on this, I am having the same issues. Most sensors show disconnected, then re connect randomly.

5

I think it’s HA not Node red… but no fix as yet

6

Did you get anywhere with this? I have had the same issue for a year now. It occurs around once a week. In the NodeRed gui the trigger nodes show “disconnected” and every few seconds change to “running” for less then a second, then flick back to disconnected.

I am running NodeRed within HA, but had the same issue when NodeRed was a separate docker from HA.

A restart of NodeRed resolves the problem for a few days.
