SignalK-Polar
#plugins-and-webapps Anyone using the signalK-polar plugin https://github.com/joabakk/signalk-polar and can give some advice as to why I do not see any data in it? Only like this:
Restart Signalk when can01 is "lost"
Is it possible to trigger an restart of the signalk service when a connection is lost? i.e. no data is recieved as in the screenshot? The reason being is that after the can01 is lost, the derived-data plugin continues to calculate incorrect values, based on latest measurments from the can01 (along with other gps data?). See screenshot for forther details. Restart the service will stop the derived-data from computing.
Thanks!...
node-red to signal K for 4G RSSI from router
My next project is to try and get the onboard 4g signal strength to show on a kip dashboard.
Hoping to have node-red ping the onboard router (via ssh) to get the below response. Parse it to json format and extract the rssi before injecting into signalk format.
Anyone done this or got any tips?...
How do I enable more debugging information in SK Server?
I am transmitting a PGN (leeway) on the bus. I can see it in the list of PGNs but it doesn't show up under a path. I have probably set a field incorrectly. I would like to determine why it's being dropped. I see it in the log for the bus but not in the server logs. I have tried guessing a few likely settings in server logging but no luck so far.
Why do I have two different speeds over ground?
See this screenshot. I have an em-trak AIS connected over USB and no other devices. Why does Signal K receive two different speeds? What do the words AIS.AI and AIS.GN mean?
Need some help debugging code for Ultrasonic Tank Sensor
Hello everyone, my first post.
In github there is this code https://github.com/frewie/UltrasonicTankSensor.git - which allows for an ultrasonic tank sensor to be connected to the underside of a tank, the sensor sends a ping through the tank to the top of the fluid level and gives the time taken for the ping to return to the sensor thereby measuring height, from which volume can be calculated. This information is then sent to SignalK. The code is a little old - may have been written prior to SensESP v2.
I'm new to coding and can't get the code to compile, even when pegging all dependent library versions. (I'm looking to run this on a ESP-32 board.) I've also tried to uplift the code to SensESP 2 following the guidance on the SignalK site, but no luck. I've spent a number of days on this and I'm sure someone will be able to take a quick look and spot the issue right away!...
