Watchdog_pi plugin - Apparent wind angle and speed N/A error

[volksbar]

Hello,

I would like to use the watchdog_pi plugin to monitor the apparent wind angle and speed. But I got “Wind N/A 0” reading and no alarms are triggered unsurprisingly.

However, the watchdog works for speed monitoring.

The calypso wind meter sends wind data via can0 to SignalK and SignalK sends further the NMEA sentences to OpenCPN. In the debug window of OpenCPN, I could see the wind data NMEA sentence being transmitted correctly: “$IIVWR, 88.00, R, 14.38, N, 7.40, M, 26.64, checksum”.

Any hints to trouble shoot this? Does anyone know if watchdog expect something other than “$IIVWR”? Many thanks!

VWR won't work, you need MWV instead. This plugin can convert from one to the other, sort of. https://opencpn.org/OpenCPN/plugins/nmeaconvert.html You'll be able to get speed, but the angle will be wrong, because there's no way to convert the angle formats from one to the other with the plug-in.
I have the same issue, and solve it with https://www.yachtd.com/products/wifi_router.html which can do the conversion (and a lot more, this is one of my favorite pieces of equipment on the boat, great value for the $)

Perfect! That helps a lot! Many thanks for the hints!
