Hi there,
I have spent many hours trying to get this to work, and I just can’t work it out. At least not without some more information. So I have a couple of questions.

1. It indicates in the code that there should be a web server for configuration, is there a URL endpoint? Or is it just the ip address of the d1 mini?

2. Does the circuit need to be connected to the spa before the webserver will start?

3. Does the circuit need to be connected to the spa before the MQTT will start?

4. Is there a web enabled terminal screen for de-bugging?

5. I am seeing the following message in the terminal when the D1 mini is plugged into usb, where is this getting derived from?

6. Is it possible to get the URL for the web server added to this message to make it easier to find.
