Stops pulling data

[andrewheathfield17-creator]

All entities etc work 100%

2 or 3 times a day it just freezes when pulling info.

I will then need to reload the integration and then it works perfectly again.

This is with the latest update... Not sure what the issue is.

same here but less frequent.
appears afaics every two days.
after reloading everything works again.

I'm getting this every time my network access to the unit becomes unavailable.

It never attempts to reconnect/reload itself.
