No. I said autoupdate because I meant autoupdate, and I said Item because I meant Item, which has no command poll period property.
Autoupdate is an internal openHAB feature that operates purely on Items.
It listens for Item commands, and predicts then sets Item state, in order to speed up response times for clicking UI users.
It’s enabled on each Item by default, and can be disabled on any individual Item.
Because it generates Item state changes in response to commands, it is really unhelpful if you are trying to analyse a command-response problem with a real device.
So my recommendation is to disable autoupdate on your test Item, at least for now.
