Node-Red / MQTT Thread - BartStevens - 2020-01-13 All, Would be nice if people could share their: - Sensors - Formulas - Dashboards - Node Red Flows etc in one (easy to find Thread) So people can use them as well. So we can create a NR library, next to the App Store in SignalK How cool would that be? Bart PS (I have difficulty to get data into SignalK; and from there into Node red. But I'm even doubting if I do it right. Maybe the flow has to be from : Arduino (via Wifi) - > raspi -> to MQTT - > to Node Red -> to SignalK) But even that is difficult to find (as a newbie) RE: Node-Red / MQTT Thread - PaddyB - 2020-01-13 (2020-01-13, 12:19 PM)BartStevens Wrote: PS (I have difficulty to get data into SignalK; and from there into Node red.

Might be better sending the data as signalk over UDP , means the data goes straight into signalk as numbers. Also I find it much better to just use the signalk node-red app, it has the signalk nodes ready to use. |
