openhab-addons: [tellstick] Sensor item updates get duplicated close to 100 times after lowering refresh interval

Expected Behavior

Lowering the refresh interval simply updates states of lights faster.

Current Behavior

The state of lights is updated faster as expected, but in addition, the sensor updates are repeated close to 100 times within less than a second.

Notes about the behavior:

• The default refresh interval was changed from 60 s to 3 s
• After resetting the refresh interval back to the original, issue disappeared
• Issue is accumulating over time. Within an hour, a few extra updates are seen, after months 75 updates have been counted
• The issue seems to affect other bindings as well: My Verisure binding (also communicating over an API) also gets duplicated sensor readings.
• The sensor burst readings happen at the expected time interval (every 5 min)
• Timeout expection sometimes happen (see second log below)

Example of logging:

Possible Solution

Input from rossko57 in the community thread: “This feels more like faulty task re-scheduling after query/response, in some circumstance or other (quite possibly a remote timeout, though that would be the trigger not the root cause). That would be a binding issue.”

Steps to Reproduce (for Bugs)

1. Lower tellstick refresh interval to 3s
2. Wait for a few hours
3. Observe in the log that sensor values are duplicated

Context

The excess points in the influxdb database makes graphs very slow.

A potential work around would be to only store changes in the database, but then I loose information about when sensor values are missing. E.g. in the crawl space, the humidity might not change for a whole day, which would give an empty graph.

Your Environment

Hardware: Raspberry pi 4, 4GB OS: openhabian openHAB version: 3.3.0.M3 Persistence: Influxdb Configuration method: GUI only, no files. Semantic model is used Tellstick usage: Live (cloud API)
