ESP32 firmware v1.3.2 Changelog:

• Fixed sensor 2 setting values for sensor 1 on display.
• Changed check if dht value read is nan to atleast set the value that is not nan (if temp is nan and hum is not, set hum, ignore temp).
• Added Text to Configuration.h that WifiManager Blocking will disable buttons on hotspot message box.

There was a problem with the sensor reading/displaying.
The Display uses "ISO 8859-15" for text encodig.
When sending the degrees ° symbol it would display as weird A°

I will no longer attach the firmware.bin file as this prevents you from changing configuration.
Compile it yourself. If you don't know how, please look at the Wiki.

First release with everything working

This is my first release for my Enclosure Controller Based on the ESP32.

Versions:

• ESP32 -> v1.3.1
• Display -> v1.3.1
• PCB -> 1.7.1

firmware.bin = for ESP32
Gerbers.v1.7.1.zip = for ordering pcb (made with jlcpcb cam processor)
NextionDesignerFile.tft = for Nextion Display

Some stuff is still missing from Documentation (Wiki).
This will be added at some point.

For the current features in this release see main readme and wiki.

Hope someone likes this.

Attached are all precompiled/premade files needed to get the pcb version (to be ordered) (excluding stl files, please see thingiverse for this).
