G5 Bullet - Binding stops working properly after roughly two hours

[ErikDB87]

I started the issue because an item linked to the channel is-dark of my G5 Bullet remained NULL, even though it's been night and day several times since creating the item. This is inconvenient, since I want a lamp lit when there's motion when it's dark, but not during the day, obviously.

I later found out that it looks like the binding runs into an issue somewhat two hours after openHAB restart (see below - post of 29/7).

I'm on: Protect version 4.0.33 Unifi OS version 4.0.6 G5 Bullet firmware version 4.71.133 openHAB version 4.2.0
