signalk-node-server plugin that tracks all-time high or low value for a path and publishes that value.
e.g. - It can track environment.wind.speedTrue and publish environment.wind.speedTrue.max.
-
Tracked values will persist across SignalK server restarts.
-
You can optionally set a description and display name for the calculated value.
-
Units are copied from the orignal path. e.g. -
m/sforenvironment.wind.speedTrue. -
Calculated values can be reset individually by ticking "Reset value" and then "Submit".
More calculations to be added in future versions
