eisbaeeer / co2light Goto Github PK

Hi,

After doing the OTA update from 2.71 I noticed that my CO2light appears to be left disfunctional. I then disassembled it and manually flashed version 2.71. Eventually the CO2light came back to live. I did some tests with all the following versions and it turned out that I can flash my way up to version 3.0 without any problem. Manually flashing 3.1 again left me with a dead light. I have erased the flash prior to flashing a new version every time.

There have been no errors during the flashing process, so I guess there is something wrong with the firmware.

The MQTT password is visible in configuration.

Supporting different types of displays would be nice.
SH110X displays are pin compatible with the used SSD1306 displays.
Changes made (substituted, not yet configurable):
-#include <Adafruit_SSD1306.h>
+#include <Adafruit_SH110X.h>

-Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, -1);
+Adafruit_SH1106G display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, -1);

-if(!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) {
- Serial.println(F("SSD1306 allocation failed"));
+if(!display.begin(0x3C, true)) {
+ Serial.println(F("SH1106G allocation failed"));

-display.setTextColor(WHITE);
+display.setTextColor(SH110X_WHITE);

Adding support for SHT3x sensor for Humidity & Temperature.
