+# Welcome to the battery usermod! 🔋
+
+Enables battery level monitoring of your project.
+
+For this to work, the positive side of the (18650) battery must be connected to pin `A0` of the d1 mini/esp8266 with a 100k Ohm resistor (see [Useful Links](#useful-links)).
+
+If you have an ESP32 board, connect the positive side of the battery to ADC1 (GPIO32 - GPIO39)

+     * It will be called by WLED when settings are actually saved (for example, LED settings are saved)
+     * If you want to force saving the current state, use serializeConfig() in your loop().
+     * 
+     * CAUTION: serializeConfig() will initiate a filesystem write operation.
+     * It might cause the LEDs to stutter and will cause flash wear if called too often.
+     * Use it sparingly and always in the loop, never in network callbacks!
+     * 
+     * addToConfig() will make your settings editable through the Usermod Settings page automatically.
+     *
+     * Usermod Settings Overview:
+     * - Numeric values are treated as floats in the browser.
+     *   - If the numeric value entered into the browser contains a decimal point, it will be parsed as a C float
+     *     before being returned to the Usermod.  The float data type has only 6-7 decimal digits of precision, and
+     *     doubles are not supported, numbers will be rounded to the nearest float value when being parsed.
+     *     The range accepted by the input field is +/- 1.175494351e-38 to +/- 3.402823466e+38.
+     *   - If the numeric value entered into the browser doesn't contain a decimal point, it will be parsed as a
+     *     C int32_t (range: -2147483648 to 2147483647) before being returned to the usermod.
+     *     Overflows or underflows are truncated to the max/min value for an int32_t, and again truncated to the type
+     *     used in the Usermod when reading the value from ArduinoJson.
+     * - Pin values can be treated differently from an integer value by using the key name "pin"
+     *   - "pin" can contain a single or array of integer values
+     *   - On the Usermod Settings page there is simple checking for pin conflicts and warnings for special pins
+     *     - Red color indicates a conflict.  Yellow color indicates a pin with a warning (e.g. an input-only pin)
+     *   - Tip: use int8_t to store the pin value in the Usermod, so a -1 value (pin not set) can be used
+     *
+     * See usermod_v2_auto_save.h for an example that saves Flash space by reusing ArduinoJson key name strings
+     * 
+     * If you need a dedicated settings page with custom layout for your Usermod, that takes a lot more work.  
+     * You will have to add the setting to the HTML, xml.cpp and set.cpp manually.
+     * See the WLED Soundreactive fork (code and wiki) for reference.  https://github.com/atuline/WLED
+     * 
+     * I highly recommend checking out the basics of ArduinoJson serialization and deserialization in order to use custom settings!

 To query or change the PIR sensor state the methods `bool PIRsensorEnabled()` and `void EnablePIRsensor(bool enable)` are available.

I use 12V WS2815 LED strips for my projects, and power them with 12V power supplies, so the regulator drops the voltage to the 5V level I need to power the ESP module and the level shifter.  If there is any interest in this case, which elevates the board and display on some custom extended headers to make place the screen at the top of the enclosure (with accessible buttons), let me know, and I could post the STL files.

+I have designed a 3D printed case around this board and an ["ElectroCookie"](https://amzn.to/2WCNeeA) project board, a [level shifter](https://amzn.to/3hbKu18), a [buck regulator](https://amzn.to/3mLMy0W), and a DC [power jack](https://amzn.to/3phj9NZ).  I use 12V WS2815 LED strips for my projects, and power them with 12V power supplies. The regulator supplies 5V for the ESP module and the level shifter.  If there is any interest in this case which elevates the board and display on custom extended standoffs to place the screen at the top of the enclosure (with accessible buttons), let me know, and I will post the STL files.

-     * If you want to force saving the current state, use serializeConfig() in your loop().
-     *

-     * It might cause the LEDs to stutter and will cause flash wear if called too often.
-     * Use it sparingly and always in the loop, never in network callbacks!
-     * 
-     * addToConfig() will make your settings editable through the Usermod Settings page automatically.
-     *
-     * Usermod Settings Overview:
-     * - Numeric values are treated as floats in the browser.
-     *   - If the numeric value entered into the browser contains a decimal point, it will be parsed as a C float
-     *     before being returned to the Usermod.  The float data type has only 6-7 decimal digits of precision, and
-     *     doubles are not supported, numbers will be rounded to the nearest float value when being parsed.
-     *     The range accepted by the input field is +/- 1.175494351e-38 to +/- 3.402823466e+38.
-     *   - If the numeric value entered into the browser doesn't contain a decimal point, it will be parsed as a
-     *     C int32_t (range: -2147483648 to 2147483647) before being returned to the usermod.
-     *     Overflows or underflows are truncated to the max/min value for an int32_t, and again truncated to the type
-     *     used in the Usermod when reading the value from ArduinoJson.
-     * - Pin values can be treated differently from an integer value by using the key name "pin"
-     *   - "pin" can contain a single or array of integer values
-     *   - On the Usermod Settings page there is simple checking for pin conflicts and warnings for special pins
-     *     - Red color indicates a conflict.  Yellow color indicates a pin with a warning (e.g. an input-only pin)
-     *   - Tip: use int8_t to store the pin value in the Usermod, so a -1 value (pin not set) can be used
-     *
-     * See usermod_v2_auto_save.h for an example that saves Flash space by reusing ArduinoJson key name strings
-     * 
-     * If you need a dedicated settings page with custom layout for your Usermod, that takes a lot more work.  
-     * You will have to add the setting to the HTML, xml.cpp and set.cpp manually.
-     * See the WLED Soundreactive fork (code and wiki) for reference.  https://github.com/atuline/WLED
-     * 
-     * I highly recommend checking out the basics of ArduinoJson serialization and deserialization in order to use custom settings!

-# Blynk controllable relay
-This usermod allows controlling a relay state from the user variables. It also allows the user variables to be set over Blynk.
-
-Optionally, the servo can have a reset timer to go back to it's default state after an interval. This interval is set through userVar1.
-
-## Instalation
-
-Replace the WLED06_usermod.ino file in Aircoookies WLED folder with the one here.
-
-## Customizations
-
-Update the following parameters in WLED06_usermod.ino to configure the mod's behavior:
-
-```cpp
-//Which pin is the relay connected to
-#define RELAY_PIN 5
-//Which pin state should the relay default to
-#define RELAY_PIN_DEFAULT LOW
-//If >0 The controller returns to RELAY_PIN_DEFAULT after this time in milliseconds
-#define RELAY_PIN_TIMER_DEFAULT 3000
-
-//Blynk virtual pin for controlling relay
-#define BLYNK_USER_VAR0_PIN V9

+# BobLight usermod
+
+This usermod allows displaying BobLight ambilight protocol on WLED device with a limited command set (not a full implementation).
+BobLight protocol uses a TCP connection which guarantees packet delivery at the possible expense of latency delays. It is not very efficient (as it uses plaintext comands) so is not suited for large number of LEDs.
+
+This implementation is intended for TV backlight in combination with XBMC/Kodi BobLight add-on.
+
+The LEDs can be configured in usermod settings page. The configuration is simple: you enter the number of LED pixels on each side of your TV (top, right, bottom, left).
+The LEDs should be wired in a clockwise orientation starting in the middle of bottom side (left half of bottom leds is where the string should start).

 ## Some words about the (optional) OLED
 This mod has been optimized for an SSD1306 driven 128x64 OLED. Using a smaller OLED or an OLED using a different driver will result in unexpected results.
 I highly recommend using these "two color monochromatic OLEDs", which have the first 16 pixels in a different color than the other 48, e.g. a yellow/blue OLED.
-Also note, you need to have an **SPI** driven OLED, **not i2c**!
+Note: you _must_ use an **SPI** driven OLED, **not an i2c one**!
 
 ### Limitations combined with Ethernet
-The initial development of this mod had been done with a beta version of the QuinLED-An-Penta, which had a different IO layout for the OLED: The CS pin used to be IO_0, but has been changed to IO27 with the first v1 public release. Unfortunately, IO27 is used by the Ethernet boards, so WLED will not let you enable the OLED screen, if you're using it with Ethernet. This unfortunately makes the development I've done to support/show Ethernet information void, as it cannot be used.

-However (and I've not tried this, as I don't own a v1 board): You can try to modify this mod and try to use IO27 for the OLED and share it with the Ethernet board. It is "just" the chip select pin, so there is a chance that both can coexist and use the same IO. You need to skip WLEDs PinManager for the CS pin, so WLED will not block using it. If you don't know how this works: Leave it. If you know what I'm talking about: Try it and please let me know on the Intermit.Tech (QuinLED) Discord server: https://discord.gg/WdbAauG

 ### My OLED flickers after some time, what should I do?
-That's a tricky one: During development I saw that the OLED sometimes starts to "bug out" / flicker and won't work anymore. This seems to be caused by the high PWM interference the board produces. It seems to loose its settings and then doesn't know how to draw anymore. Turns out the only way to fix this is to call the libraries `begin()` method again which will re-initialize the display.

+
+## Requirements
+* "SHT85" by Rob Tillaart, v0.2 or higher: https://github.com/RobTillaart/SHT85
+
+## Usermod installation
+Simply copy the below block (build task) to your `platformio_override.ini` and compile WLED using this new build task. Or use an existing one, add the buildflag `-D USERMOD_SHT` and the below library dependencies.
+
+ESP32:

+extends = env:esp32dev
+build_flags = ${common.build_flags_esp32}

+
+## MQTT Discovery for Home Assistant
+If you're using Home Assistant and want to have the temperature and humidity available as entities in HA, you can tick the "Add-To-Home-Assistant-MQTT-Discovery" option in the usermod settings. If you have an MQTT broker configured under "Sync Settings" and it is connected, the mod will publish the auto discovery message to your broker and HA will instantly find it and create an entity each for the temperature and humidity.
+
+### Publishing readings via MQTT
+Regardless of having MQTT discovery ticked or not, the mod will always report temperature and humidity to the WLED MQTT topic of that instance, if you have a broker configured and it's connected.
+
+## Configuration
+Navigate to the "Config" and then to the "Usermods" section. If you compiled WLED with `-D USERMOD_SHT`, you will see the config for it there:
+* SHT-Type:
+  * What it does: Select the SHT sensor type you want to use
+  * Possible values: SHT30, SHT31, SHT35, SHT85
+  * Default: SHT30
+* Unit:
+  * What it does: Select which unit should be used to display the temperature in the info section. Also used when sending via MQTT discovery, see below.
+  * Possible values: Celsius, Fahrenheit
+  * Default: Celsius
+* Add-To-HA-MQTT-Discovery:
+  * What it does: Makes the temperature and humidity available via MQTT discovery, so they're automatically added to Home Assistant, because that way it's typesafe.
+  * Possible values: Enabled/Disabled
+  * Default: Disabled
+
+## Change log
+2022-12
+* First implementation.

+# Klipper Percentage Usermod
+This usermod polls the Klipper API every 10s for the progressvalue.
+The leds are then filled with a solid color according to that progress percentage. 
+the solid color is the secondary color of the segment.
+
+A corresponding curl command would be:
+```
+curl --location --request GET 'http://[]/printer/objects/query?virtual_sdcard=progress'
+```
+## Usage
+Compile the source with the buildflag  `-D USERMOD_KLIPPER_PERCENTAGE` added.
+
+You can also use the WLBD bot in the Discord by simply extending an exsisting build enviroment:
+```
+[env:esp32klipper]
+extends = env:esp32dev
+build_flags = ${common.build_flags_esp32} -D USERMOD_KLIPPER_PERCENTAGE
+```
+
+## Settings 
+
+### Enabled:
+Checkbox to enable or disable the overlay
+
+### Klipper IP: 
+IP adress of your Klipper instance you want to poll. ESP has to be restarted after change
+
+### Direction : 
+0 = normal
+
+1 = reversed
+
+2 = center
