All,
Been doing what you all also are doing ... getting better at SignalK.
What I have/did so far:
- raspi + DAIsy up and running
- ESP flashed via easyESP
- Connected a Temp Sensor to ESP
- Have NodeRed up an running
What I need help with now is how to link ESP to MQTT on Raspi.
I have already read a lot, but can not get my head around certain aspects
Questions
- I have MQTT installed on my Raspi
- I have the Node Red and MQTT nodes ready, but also found a MQTT Broker in the "App Store of Node Red"
- Have my ESP on the AP of the Raspi (can configure it via browser of the Raspi
- IP address of Raspi is 192.168.86.44
1. What is the adres MQTT server? I think 192.168.86.44:1883
2. On the ESP (after flashing via EasyESP) I can configure 3 or 4 different connections to MQTT. But which one?
3. On the UI of the ESP (url 10.10.10.137) I can furthermore configure a generic heat sensor, which I see on this page as well (=the temp reading), but how to publish this to the (right MQTT)
4. And then in Node Red; how do I configure the Node? Do I use 192.168.86.44:1883? And how do I subscribe to the Temp readings?
All, again, I'm a newbie and try to understand it (every day a bit more). I see you discuss much more complex things, but see if you can help me just a bit further.
Best,
Bart
