Wave height calculation

Turns out it wasnt quite as simple as i thought above but not far off. You have to take sin and cos of the angle, do your averaging on each of those and then use Math.atan2(averagesin,averagecos). Just in case this is of any use to anyone else!

That's it! It seems so simple now. Take the sin of the angle, do the averaging and then take the inverse sine of the result! Thank you!

New Beta release of bt-sensors-plugin-sk

I found it in the end it was located here (./data/conf/signalk/plugin-config-data) I've looked in the json and the encryption key is correct in there (set to the same as the bluetooth password on the device)

New Beta release of bt-sensors-plugin-sk

I did have a box to enter the encryption key but its since disappeared (which presumably is just the bluetooth passkey?). Sorry, excuse my ignorance but i've got SSH access to the Cerbo but i dont have a ~/.signalk folder. Should i be logged in under a different user? (currently root)

Ruuvi Tag Data to NMEA via Cerbo Issue

Apologies, just realised i'm using the plugin wrong. I put the new path in the source box by mistake. I'll re-map it in node-red
