+# Usermod Animated Staircase
+This usermod makes your staircase look cool by switching it on with an animation. It uses
+PIR or ultrasonic sensors at the top and bottom of your stairs to:
+
+- Light up the steps in your walking direction, leading the way.
+- Switch off the steps after you, in the direction of the last detected movement.
+- Always switch on when one of the sensors detects movement, even if an effect
+  is still running. It can therewith handle multiple people on the stairs gracefully.
+
+The Animated Staircase can be controlled by the WLED API. Change settings such as
+speed, on/off time and distance settings by sending an HTTP request, see below.
+
+## WLED integration
+To include this usermod in your WLED setup, you have to be able to [compile WLED from source](https://github.com/Aircoookie/WLED/wiki/Compiling-WLED).
+
+Before compiling, you have to make the following modifications:
+
+Edit `usermods_list.cpp`:
+1. Open `wled00/usermods_list.cpp`
+2. add `#include "../usermods/Animated_Staircase/Animated_Staircase.h"` to the top of the file
+3. add `usermods.add(new Animated_Staircase());` to the end of the `void registerUsermods()` function.
+
+Edit `Animated_Staircase_config.h`:
+1. Open `usermods/Animated_Staircase/Animated_Staircase_config.h` 
+2. To use PIR sensors, change these lines to match your setup:
+   Using D7 and D6 pin notation as used on several boards:
+  
+   ```cpp
+     #define TOP_PIR_PIN    D7
+     #define BOTTOM_PIR_PIN D6
+   ```
+   
+   Or using GPIO numbering for pins 25 and 26:
+   ```cpp
+     #define TOP_PIR_PIN    26
+     #define BOTTOM_PIR_PIN 25
+   ```
+
+   To use Ultrasonic HC-SR04 sensors instead of (one of the) PIR sensors,
+   uncomment one of the PIR sensor lines and adjust the pin numbers for the
+   connected Ultrasonic sensor. In the example below we use an Ultrasonic
+   sensor at the bottom of the stairs:
+
+   ```cpp
+   #define TOP_PIR_PIN 32
+   //#define BOTTOM_PIR_PIN D6 /* This PIR sensor is disabled   */
+
+   #ifndef TOP_PIR_PIN
+   #define TOP_SIGNAL_PIN D2
+   #define TOP_ECHO_PIN   D3
+   #endif
+
+   #ifndef BOTTOM_PIR_PIN      /* If the bottom PIR is disabled, */
+   #define BOTTOM_SIGNAL_PIN 25 /* This Ultrasonic sensor is used */
+   #define BOTTOM_ECHO_PIN   26
+   #endif
+   ```
+
+After these modifications, compile and upload your WLED binary to your board
+and check the WLED info page to see if this usermod is enabled.
+
+## Hardware installation
+1. Stick the LED strip under each step of the stairs.
+2. Connect the ESP8266 pin D4 or ESP32 pin D2 to the first LED data pin at the bottom step
+   of your stairs.
+3. Connect the data-out pin at the end of each strip per step to the data-in pin on the 
+   other end of the next step, creating one large virtual LED strip.
+4. Mount sensors of choice at the bottom and top of the stairs and connect them to the ESP.
+5. To make sure all LEDs get enough power and have your staircase lighted evenly, power each
+   step from one side, using at least AWG14 or 2.5mm^2 cable. Don't connect them serial as you
+   do for the datacable!
+
+You _may_ need to use 10k pull-down resistors on the selected PIR pins, depending on the sensor.
+
+## WLED configuration
+1. In the WLED UI, confgure a segment for each step. The lowest step of the stairs is the 
+   lowest segment id. 
+2. Save your segments into a preset. 
+3. Ideally, add the preset in the config > LED setup menu to the "apply 
+   preset **n** at boot" setting.
+
+## Changing behavior through API
+The Staircase settings can be changed through the WLED JSON api.
+
+**NOTE:** We are using [curl](https://curl.se/) to send HTTP POSTs to the WLED API.
+If you're using Windows and want to use the curl commands, replace the `\` with a `^`
+or remove them and put everything on one line.
+
+
+| Setting          | Description                                                   | Default |
+|------------------|---------------------------------------------------------------|---------|
+| enabled          | Enable or disable the usermod                                 | true    |
+| segment-delay-ms | Delay (milliseconds) between switching on/off each step       | 150     |
+| on-time-s        | Time (seconds) the stairs stay lit after last detection       | 5       |
+| bottom-echo-us   | Detection range of ultrasonic sensor                          | 1749    |
+| bottomsensor     | Manually trigger a down to up animation via API               | false   | 
+| topsensor        | Manually trigger an up to down animation via API              | false   |
+
+
+To read the current settings, open a browser to `http://xxx.xxx.xxx.xxx/json/state` (use your WLED 
+device IP address). The device will respond with a json object containing all WLED settings. 
+The staircase settings and sensor states are inside the WLED status element:
+
+```json
+{
+    "state": {
+        "staircase": {
+            "enabled": true,
+            "segment-delay-ms": 150,
+            "on-time-s": 5,
+            "bottomsensor": false,
+            "topsensor": false
+        },
+}
+```
+
+### Enable/disable the usermod
+By disabling the usermod you will be able to keep the LED's on, independent from the sensor
+activity. This enables to play with the lights without the usermod switching them on or off.
+
+To disable the usermod:
+
+```bash
+curl -X POST -H "Content-Type: application/json" \
+     -d {"staircase":{"enabled":false}} \
+     xxx.xxx.xxx.xxx/json/state
+```
+
+To enable the usermod again, use `"enabled":true`.
+
+### Changing animation parameters
+To change the delay between the steps to (for example) 100 milliseconds and the on-time to
+10 seconds:
+
+```bash
+curl -X POST -H "Content-Type: application/json" \
+     -d '{"staircase":{"segment-delay-ms":100,"on-time-s":10}}' \
+     xxx.xxx.xxx.xxx/json/state
+```
+
+### Changing detection range of the ultrasonic HC-SR04 sensor
+When an ultrasonic sensor is enabled in `Animated_Staircase_config.h`, you'll see a 
+`bottom-echo-us` setting appear in the json api:
+
+```json
+{
+    "state": {
+        "staircase": {
+            "enabled": true,
+            "segment-delay-ms": 150,
+            "on-time-s": 5,
+            "bottom-echo-us": 1749
+        },
+}
+```
+
+If the HC-SR04 sensor detects an echo within 1749 microseconds (corresponding to ~30 cm 
+detection range from the sensor), it will trigger switching on the staircase. This setting 
+can be changed through the API with an HTTP POST:
+
+```bash
+curl -X POST -H "Content-Type: application/json" \
+     -d '{"staircase":{"bottom-echo-us":1166}}' \
+     xxx.xxx.xxx.xxx/json/state
+```
+
+Calculating the detection range can be performed as follows: The speed of sound is 343m/s at 20 
+degrees Centigrade. Since the sound has to travel back and forth, the detection range for the
+sensor in cm is (0.0343 * maxTimeUs) / 2. To get you started, please find delays and distances below:
+
+| Distance | Detection time  |
+|---------:|----------------:|
+|     5 cm |          292 uS |
+|    10 cm |          583 uS |
+|    20 cm |         1166 uS |
+|    30 cm |         1749 uS |
+|    50 cm |         2915 uS |
+|   100 cm |         5831 uS |
+
+**Please note:** that using an HC-SR04 sensor, particularly when detecting echos at longer
+distances creates delays in the WLED software, and _might_ introduce timing hickups in your animations or
+a less responsive web interface. It is therefore advised to keep the detection time as short as possible.
+
+### Animation triggering through the API
+Instead of stairs activation by one of the sensors, you can also trigger the animation through
+the API. To simulate triggering the bottom sensor, use:
+
+```bash
+curl -X POST -H "Content-Type: application/json" \
+     -d '{"staircase":{"bottomsensor":true}}' \
+     xxx.xxx.xxx.xxx/json/state
+```
+
+Likewise, to trigger the top sensor, use:
+
+```bash
+curl -X POST -H "Content-Type: application/json" \
+     -d '{"staircase":{"topsensor":true}}' \
+     xxx.xxx.xxx.xxx/json/state
+```
+
+Have fun with this usermod.<br/>

usermods/BME280_v2/README.md

@@ -0,0 +1,40 @@
+Hello! I have written a v2 usermod for the BME280/BMP280 sensor based on the [existing v1 usermod](https://github.com/Aircoookie/WLED/blob/master/usermods/Wemos_D1_mini%2BWemos32_mini_shield/usermod_bme280.cpp). It is not just a refactor, there are many changes which I made to fit my use case, and I hope they will fit the use cases of others as well! Most notably, this usermod is *just* for the BME280 and does not control a display like in the v1 usermod designed for the WeMos shield. 
+
+- Requires libraries `BME280@~3.0.0` (by [finitespace](https://github.com/finitespace/BME280)) and `Wire`. Please add these under `lib_deps` in your `platform.ini` (or `platform_override.ini`).
+- Data is published over MQTT so make sure you've enabled the MQTT sync interface.
+- This usermod also writes to serial (GPIO1 on ESP8266). Please make sure nothing else listening on the serial TX pin of your board will get confused by log messages!
+
+To enable, compile with `USERMOD_BME280` defined (i.e. `platformio_override.ini`)
+```ini
+build_flags =
+  ${common.build_flags_esp8266}
+  -D USERMOD_BME280
+```
+or define `USERMOD_BME280` in `my_config.h`
+```c++
+#define USERMOD_BME280
+```
+
+Changes include:
+- Adjustable measure intervals
+  - Temperature and pressure have separate intervals due to pressure not frequently changing at any constant altitude
+- Adjustment of number of decimal places in published sensor values
+  - Separate adjustment for temperature, humidity and pressure values
+  - Values are rounded to the specified number of decimal places
+- Pressure measured in units of hPa instead of Pa
+- Calculation of heat index (apparent temperature) and dew point
+  - These, along with humidity measurements, are disabled if the sensor is a BMP280
+- 16x oversampling of sensor during measurement
+- Values are only published if they are different from the previous value
+- Values are published on startup (continually until the MQTT broker acknowledges a successful publication)
+
+Adjustments are made through preprocessor definitions at the start of the class definition.
+
+MQTT topics are as follows:
+Measurement type | MQTT topic
+--- | ---
+Temperature | `<deviceTopic>/temperature`
+Humidity | `<deviceTopic>/humidity`
+Pressure | `<deviceTopic>/pressure`
+Heat index | `<deviceTopic>/heat_index`
+Dew point | `<deviceTopic>/dew_point`

+
+### PlatformIO requirements
+
+If you are using `platformio_override.ini`, you should be able to refresh the task list and see your custom task, for example `env:d1_mini_usermod_dht_C`. If not, you can add the libraries and dependencies into `platformio.ini` as you see fit.
+
+
+## Change Log
+
+2020-02-04
+* Change default QuinLed pin to Q2
+* Instead of trying to keep updates at constant cadence, space readings out by measurement interval; hope this helps to avoid occasional bursts of readings with errors
+* Add some more (optional) stats
+2020-02-03
+* Due to poor readouts on ESP32 with previous DHT library, rewrote to use https://github.com/alwynallan/DHT_nonblocking
+* The new library serializes/delays up to 5ms for the sensor readout  
+2020-02-02 
+* Created

+# Auto Save
+
+v2 Usermod to automatically save settings 
+to preset number AUTOSAVE_PRESET_NUM after a change to any of
+
+* brightness
+* effect speed
+* effect intensity
+* mode (effect)
+* palette
+
+but it will wait for AUTOSAVE_SETTLE_MS milliseconds, a "settle" 
+period in case there are other changes (any change will 
+extend the "settle" window).
+
+It will additionally load preset AUTOSAVE_PRESET_NUM at startup.
+during the first `loop()`.  Reasoning below.
+
+AutoSaveUsermod is standalone, but if FourLineDisplayUsermod is installed, it will notify the user of the saved changes.
+
+Note: I don't love that WLED doesn't respect the brightness of the preset being auto loaded, so the AutoSaveUsermod will set the AUTOSAVE_PRESET_NUM preset in the first loop, so brightness IS honored. This means WLED will effectively ignore Default brightness and Apply N preset at boot when the AutoSaveUsermod is installed.
+
+## Installation
+
+Copy and update the example `platformio_override.ini.sample` 
+from the Rotary Encoder UI usermode folder to the root directory of your particular build.
+This file should be placed in the same directory as `platformio.ini`.
+
+### Define Your Options
+
+* `USERMOD_AUTO_SAVE`   - define this to have this the Auto Save usermod included wled00\usermods_list.cpp
+* `USERMOD_FOUR_LINE_DISLAY`   - define this to have this the Four Line Display mod included wled00\usermods_list.cpp - also tells this usermod that the display is available (see the Four Line Display usermod `readme.md` for more details)
+* `AUTOSAVE_SETTLE_MS`         - Minimum time to wave before auto saving, defaults to 10000  (10s)
+* `AUTOSAVE_PRESET_NUM`        - Preset number to auto-save to, auto-load at startup from, defaults to 99
+
+### PlatformIO requirements
+
+No special requirements.
+
+Note: the Four Line Display usermod requires the libraries `U8g2` and `Wire`.

+# Rotary Encoder UI Usermod
+
+First, thanks to the authors of the ssd11306_i2c_oled_u8g2 mod.
+
+This usermod provides a four line display using either
+128x32 or 128x64 OLED displays.
+It's can operate independently, but starts to provide
+a relatively complete on-device UI when paired with the 
+Rotary Encoder UI usermod. I strongly encourage you to use 
+them together.
+
+[See the pair of usermods in action](https://www.youtube.com/watch?v=tITQY80rIOA)
+
+## Installation
+
+Copy and update the example `platformio_override.ini.sample` 
+from the Rotary Encoder UI usermode folder to the root directory of your particular build.
+This file should be placed in the same directory as `platformio.ini`.
+
+### Define Your Options
+
+* `USERMOD_FOUR_LINE_DISLAY`   - define this to have this the Four Line Display mod included wled00\usermods_list.cpp - also tells Rotary Encoder usermod, if installed, that the display is available
+* `FLD_PIN_SCL`                - The display SCL pin, defaults to 5
+* `FLD_PIN_SDA`                - The display SDA pin, defaults to 4
+* `FLIP_MODE`                  - Set to 0 or 1
+* `LINE_HEIGHT`                - Set to 1 or 2
+
+There are other `#define` values in the Usermod that might be of interest.
+
+### PlatformIO requirements
+
+This usermod requires the `U8g2` and `Wire` libraries. See the 
+`platformio_override.ini.sample` found in the Rotary Encoder
+UI usermod folder for how to include these using `platformio_override.ini`.

+# Rotary Encoder UI Usermod
+
+First, thanks to the authors of other Rotary Encoder usermods.
+
+This usermod starts to provide a relatively complete on-device
+UI when paired with the Four Line Display usermod. I strongly
+encourage you to try them together.
+
+[See the pair of usermods in action](https://www.youtube.com/watch?v=tITQY80rIOA)
+
+## Installation
+
+Copy and update the example `platformio_override.ini.sample` to the root directory of your particular build.
+This file should be placed in the same directory as `platformio.ini`.
+
+### Define Your Options
+
+* `USERMOD_ROTARY_ENCODER_UI`  - define this to have this user mod included wled00\usermods_list.cpp
+* `USERMOD_FOUR_LINE_DISLAY`   - define this to have this the Four Line Display mod included wled00\usermods_list.cpp - also tells this usermod that the display is available (see the Four Line Display usermod `readme.md` for more details)
+* `ENCODER_DT_PIN`             - The encoders DT pin, defaults to 12
+* `ENCODER_CLK_PIN`            - The encoders CLK pin, defaults to 14
+* `ENCODER_SW_PIN`             - The encoders SW pin, defaults to 13
+
+### PlatformIO requirements
+
+No special requirements.
+
+Note: the Four Line Display usermod requires the libraries `U8g2` and `Wire`.
+
+## Change Log
+
+2021-02
