My only conclosion is that the Hue interface in the ZenseBox is not working well.
Some of the "hanging" can for sure be pinpoint to the fact that the ZenseHome switches are + 10 years old - but there stille a significantly improvement going the Home Assistant (Nore-RED) path.
Another option that I not have tested, i using the Hue palette (Plug in) for Node-RED.
