Wiser intergration


I am still on a massive learning curve with HA and all the bits that go with it and where I get an issue I am trying to sort everything out by going through the forums, you tube, Github etc. This one has got me stumped. I have pasted below an error that shows in my logs. if I clear the logs and restart it more than not reappears quickly, whereas if I leave it showing it shows a couple of occurrences over a few days. Has anyone got any idea how to solve the issue that’s causing this error.


This error originated from a custom integration.
