Tellstick Binding: Item updates get duplicated around 75 times after lowering refresh interval

Got it, thanks. I’ve updated the title and will declare an issue in GitHub

For anyone who stumbles upon the same issue, it’s fixed in the following milestone:
openHAB 3.4.0 Milestone 4

Turned out that the same issue existed in both the Tellstick and Verisure binding, so it’s possible that other bindings has it as well. The fixes are described here:
