David Sanner - Bug or odd behavior w/ Data Brow...

On further thought I don't think startup sync explains what I'm seeing. (Data Browser showing different notifications data than http://localhost:3000/signalk/v1/api/vessels/self/ ) I have three paths defined below for the tank measurement - one from SenseEsp (currentLevel) & two from derived-data. What is really odd is if all three are there everything is fine but if I remove tanks.freshWater.starboard.capacity then no notifications.tanks... information shows up under "Data Browser" - I'll report back if I see anything else (or others see this) but we may just have to put this on the "that's odd" list. { "path": "tanks.freshWater.starboard.capacity", "value": { "units": "ratio", "description": "Level of tank as ratio", "zones": [ ] } }, { "path": "tanks.freshWater.starboard.currentLevel", "value": { "units": "ratio", "description": "Level of tank as ratio", "alertMethod": [ "visual", "sound"], "zones": [ { "upper": 0.125, "lower": 0, "state": "alert", "message": "1/8 Fresh Water Tanks" } ] } }, { "path": "tanks.freshWater.starboard.currentVolume", "value": { "units": "m3", "description": "Starboard Water Tank Volume.", "zones": [ { "upper": 0.01209,"lower": -10,"state": "warn", "message": "Starboard Water Tank Low" }, { "upper": 0.0266, "lower": 0.0121, "state": "alert","message": "Starboard Water Tank 7 Gallons" } ], "alertMethod": [ "visual", "sound" ] } }

David Sanner - Bug or odd behavior w/ Data Brow...

This seems to be happening for only some notification paths (only 20% are missing?), working discovering a pattern. If you have many zones/notifications can you compare the number found under the URL to the number under the Data Browser? Thanks for the check that I'm waiting for up to 15s. I am waiting long enough... the data/measurement is there, just not the notification in some places but not all. (btw, most notification paths don't show up until data is there - plugins may be different) Key bit I think, is that the measurement and the related notification is showing up under: http://localhost:3000/signalk/v1/api/vessels/self/ But not under "Data Browser" or subscription. In my plugin I'm using "app.getSelfPath('notifications')" which it does show up under.
I redid my baseDeltas.json to have only a single zone (for this tank) and it's the same behavior. Thx.

David Sanner - Bug or odd behavior w/ Data Brow...

I wrote a simple test plugin and I'm seeing the same behavior when I subscribe to notifications but here's a test that I hope illustrates the issue. I have a SensESP sending a tank value every 15s or so: 'tanks.freshWater.starboard.currentLevel' and all looks good (values shown in Data Browser). After SK server restart I added a zone to it - shown in baseDeltas.json: { "path": "tanks.freshWater.starboard.currentLevel", "value": { "units": "ratio", "description": "Data should be of type number.", "alertMethod": [ "visual", "sound" ], "zones": [ { "upper": 0.1, "lower": 0, "state": "alert", "message": "testing" } ] } } --------- As soon as I add the zone a notification for that zone pops up in 'Data Browser' however if I restart SK server it doesn't repopulate the notification and only shows the path to the tank level measurement. However if I then view via http://localhost:3000/signalk/v1/api/vessels/self/ I find the notification: notifications.tanks.freshWater.starboard.currentLevel With proper values (eg. $source "self.notificationhandler") Again, at this point, when I look under "Data Browser" the notification doesn't show up. If I then edit the measurement's zone values it shows up but if I then restart SK server again it doesn't show up in the 'Data Browser' (or subscription) but does w/ URL above. -- So that's the inconsistency -- (I hope that makes sense / good example) Final oddness/clue: If I then go and delete the zone & method from the measurement meta data baseDeltas.json has: { "path": "tanks.freshWater.starboard.currentLevel", "value": { "units": "ratio", "description": "Data should be of type number.", "zones": null } } But this time after restart it does show the notification path (w/o zones or methods) under both 'Data Browser' and URL above. Thanks

Greg Young - @Scott Bender anchor alarm plugin...

@Greg Young The issue only happens when changing from warning (alarm state) to 'emergency' state as it wasn't updating the notification state (though it did update the state going from normal-> emergency) . This issue only popped up only with the unreleased changes Scott made back in September (refactoring and stopping continuous updating of the notification state as he pointed out should only be set once). Published version never had this issue.
Note, Scott's feedback on this lead me down the road to creating signalk-notification-player plugin which allows for custom notification playback. Version 2.0 should be out soon which includes a Webapp for viewing notification states / values.

notifications.notifications

That's what I'm thinking & my testing yesterday showed the same. Glad you could edit manually.
Not sure the fix for others, maybe a delete button or special case that removes the edit feature for paths that start with notification? Perhaps open an issue w/ SK server on github just to make sure the issue is known.

You might start by making a copy of baseDeltas.json and then removing the issues - though you have to keep the json format regular (remove all between and including {}, if last remove the trailing comma).
I've seen this pop up when I had @signalk/zones but I think what is likely happening in your case is that if you edit the meta data of a notifications.xxx.xxx entry under "Data Browser" and save it, the notification entry gets stored in baseDeltas.js which then can have the duplicate notification.notification issue after sk restarts.

Do you have zones defined by the older @signalk/zones plugin? I think it can cause this issue. (check AppStore installed / source under Data Browser) To migrate zone configuration from @signalk/zones plugin to use SK server directly, under SK Data Browser, click edit and then save for each path with a zone shown . Then disable then @signalk/zones plugin.
Cleanup: after removing @signalk/zones plugin try restarting SK ... that may help but you might have to edit baseDeltas.json
