Hi
I’ve got a TCP Modbus sensor configured which goes to my ventilation system.
The integration works fine at start up of HA. After a while it starts throwing warnings “Updating modbus sensor took longer than the scheduled update interval”.
I deducted to issue to the fact that when I connected to my ventilation system from my laptop using qModMaster the issue arose. Makes kind of sense that you can only have one connection at a time. BUT, when I disconnect from the ventilation system from the laptop and shut down qModMaster the warning in HA remains multiple times after that fact. Actually it never seems to stop. (Only stops and works fine when I reboot HA docker container)

Where’s the culprit? In HA’s implementation or the ventilation units implementation?

Hope someone can shed some light on the subject.
Thanks in advance
