Hi,
First tried discord, but did not get a reply.
So here we go 
2 weeks ago i installed HA, i am still actively using a competitor at the moment and would like to move to HA.
I have my house on NHC1, and was able to add the NHC1 integration via the config.yaml, and now i see all my entities.
But for some reason… when i turn a light on, the dashboard button jumps back to off.
Same way around, when i would turn off a light, it sets the button back to on.
BUT… then, after a few moments… the button will automatically update to the correct state.
Does this ring any bell for someone please?
Thank you
