No idea how these timers capture running time and if system load could impact this, but am using this timer (running on a Victron Cerbo) and the amount of time that passes is not very accurate. I have determined this by using system logging debug nodes. The time stamps on the events show more than the expected elapsed time.
Here are my log entries from /var/log/node-red-venus/current:
@4000000068a33b571ae03dcc 18 Aug 10:40:13 - [info] [debug:Start Time] true (Aug 18 10:40)
@4000000068a34285002fb4e4 18 Aug 11:10:51 - [info] [debug:Stop Time] false (Aug 18 11:10)
Since this is a 2% error, that seems huge.
I’m almost thinking that this problem may be specific for Node-RED running on Victron Venus OS, but could use any help that’s out there.
Please see this flow for testing:
