How to See the Data in an App ? & Simple Wiring to ESP8266 #62

I have the Code running OK on The ESP8266 D1 Mini in the VINDRIKTNING. The Serial Port is streaming measurements to my IDE Serial Monitor.

What do I have to use to see the data on an App ? (or a browser) The Config.h is untouched, I dont know what to enter ! It has somehow managed to connect to my WiFi despite not giving it an SSID or Password.

I installed Home Assistant on my Android Tablet, it asks for a URL, I dont have one The Blog does say this code works with auto discovery, but no joy.

This must be a pretty basic issue, but I cant find any tutorial related to it.

Hmm, no takers. Its a shame that for the sake of a basic tutorial on setting this up that such a complex program is likely to be abandoned. Looking at the other Issues, I am not the only person at a loss to getting this finished.

I have done numerous other ESP projects using Blynk and Thingspeak, so I will have a go at using the data in the serial feed to feed Thingspeak - has anyone else done this ?

I want to use a simple manual configuration of ssid/password for the wifi, so first task is to clear out all the code around this.

I added a Piezo buzzer between port D6 and +3.3V, very useful to indicate the WiFi has connected or whatever you want. I attach a few pics of a simple way of wiring this up using normal 1/10th inch pitch headers, tweaked so they surface mount and then supported with epoxy resin (not hot melt). I used double sided tape to fix the board (with a 3mm spacer) with the socket available for external connection, easy to reflash with it all screwed together.

After remming out about half the code and adding in Thingspeak, its working.

Probably worth doing some reading on MQTT.... Homeassistant, nodered....

I accept that, I did look at the mqtt site and the "quick start" seemed anything but ! I have used Thingspeak for a few projects and it works very well, I prefer it to Blynk. The code in this project is well beyond my capability, I am not a natural programmer.
