tzapu-
Let me say this code is amazing and has inspired me to do so much. My mom has early onset Alzheimers and I'm trying to use technology to maintain a balance of supervision and her own autonomy.
I am running the FSparameters example, and added an example for HDC1080 called closedcube here on github.

Everything works fine and will trigger an LED at a certain temp or humidity. So instead of this:

if (hdc1080.readHumidity() >= 50 || hdc1080.readTemperature() >= 30){ digitalWrite(LED, HIGH); }

I wrote this:
if (hdc1080.readHumidity() >= mqtt_port[3] || hdc1080.readTemperature() >= 30){ digitalWrite(LED, HIGH); }

And it worked well! I could change the Humidity setting to 65 or 70 or 35 and it worked flawlessly.

But after a bit of fiddling, now no matter it just triggers 48 regardless of what I input for mqtt_port.

I even have a Serial.println(mqtt_port); to see what the parameter is saved as, and it is saved correctly.

Thank you for looking

When I serial print the new value of mqtt_port, I get what I input during AP mode. However the code doesn't use that value when triggering my LED from humidity sensor. If I input 51.7, the code saves it correctly, and prints it out. Then triggers my LED at a wrong value.

I figured out how to do it. I used the 'atof' command to convert the saved parameter to a float.
