Hello,

Latest version installed (2.8.2), and also noticed in previous version, I have this error in dashboard.

It appear 1 min after first poll - let's say 15 min after SK restart, if poll interval is set at 15 min.

Log for first poll:

The weather forecast is working well in freeboard-sk even after this error.

Best regards, Seb

The message should only appear when the timer is polling more frequently than required (this is to protect against a runaway timer and limit any cost impact of exceeding API free thresholds).

From the log it appears that the timer is working correctly (log entries are time stamped 1 minute apart).

Can you please confirm this is the case, if so then it is just a fix to the logic displaying the message.

Yes indeed, timer is working as you said, every 1 minute.

Jun 02 10:12:35 2024-06-02T07:12:35.037Z @signalk/freeboard-sk Watch interval < 50 secs. (0.653 secs)

This line in the log indicates why the error is showing. The 60 sec timer was triggered 1/2 a second after the previous trigger.

I have tried reproducing it on my Pi devices with the current version of server with no success.

When this has occurred in the past (on a Pi) it required a reboot (even if running in Docker) to have the timer trigger at the correct interval.
