The ESP Easy firmware can be used to turn the ESP module into an easy multifunction sensor device for Home Automation solutions like Domoticz. Configuration of the ESP Easy is entirely web based, so once you've got the firmware loaded, you don't need any other tool besides a common web browser.

The ESP Easy firmware is currently at build R120 an looks stable enough for production purposes as long as it's being used as a sensor device.
 
  
 
ESP Easy also offers limited "low level" actuator functions but due to system instability, this could be less useful in real life applications.

ESP Easy is under continuous development as can be seen on the [https://github.com/letscontrolit/ESPEasy GitHub page] and on the [https://www.letscontrolit.com/forum/ Forum].
  
Getting started with the ESP Easy takes a few basic steps. In most cases your ESP module comes with the AT firmware or the NodeMCU LUA firmware. We need to replace the existing firmware with the ESP Easy firmware. We provide a (Windows only) flashtool to make this process an easy job.

There are so called "nightly builds" which can be found on the [https://github.com/letscontrolit/ESPEasy/releases Releases page].

Well, this is a short version of our naming convention here at the ESP Easy initiative. We started to call the extensive re-write of the source code "Mega", which is an hint of the size needed for the next big stable release. Prior to mega we allowed smaller mem-sizes (sub-megabyte, aka 512kb) for the official releases. This is a bit tight for our goal to add many more useful features to the firmware. So after a somewhat bad decision in the early days of the re-write project we started to call the development branch "Mega" instead of the more accepted name "Master". We later switched this to the correct name. The current master branch on GitHub is where all the development goes into. The legacy branch is the archive, a point zero if you like, which is the exact copy of the source code before we started the re-write. Once we have reached all the milestones for version 2.0.0 we will freeze the source from that point and fork that into a branch called v2.0, only bug fixes is going into that branch. New features that cannot wait until next v2.1 release will be branched into v2.0.1 (this might not happen if no ground breaking feature is added). New features, and experimental stuff, is poured into the development branch (master). Below you will find a explanation on how we intend to do the branching and releases of future firmware versions. Please observe that this table is not the road map, just an example to explain the different names and numbers.

As of release mega we will also try to get more hardware specific builds for especially Sonoff units. These will have much less plugins by default since they are not needed for these units, this makes flashing units with less than 1MB possible.

Nightly builds are always generated if something has been updated in the source code. So the master branch will always have many more releases than the frozen stable releases which will only have one (until a bug fix release is generated). To explain this we provide these examples:
* [[DC Voltage divider | DC Voltage divider]]

+
Master is updated on 2018-04.07 with new code, next morning you will be able to download the release "master-20180408" (current tag name for that release is "mega").<br>
 +
Master is branched into an official stable release named "v2.0" on 2018-05-07, next morning you can download "v2.0-20180508".<br>
 +
v2.0 is bug fixed on 2018-05-23, next morning you can download "v2.0-20180524" which then supersede the older v2.0.0 version.<br>

That's where this wiki is here for (among many other things). We will list all the current states from v2.0.0 and onward. Releases named "master" should always be seen as not stable and only for users that wish to experiment with new releases and test stuff to help the development of future releases.

'''WPA Key''' The key used on your Wifi Access Point
+
<div style="border-bottom:1px solid red;  background:#F6CECE; padding:0.4em 1em 0.4em;">If you are running the stock Mega edition firmware on 1MB modules, you will find that you can no longer load newer images because there's insufficient free space to upload the image (344kB as of 2.0.0.-Dev 9 edition). You can compile smaller images to solve this issue or use a small image that has been build just to upload newer images. So you would always have to use a two-step process to renew using OTA on 1MB modules. Using the uploader image as an in-between step, you can use images up to 604kB.
  
'''WPA AP Mode Key''' The key that ESP Easy will use if it starts as a Wifi Access Point to set the first time configuration
+
* Only devices with 1Mb or more flash are supported.
 +
* To use OTA you need more then 1Mb of flash. (otherwise your device will get unreachable via wireless and you need to fix it via serial)
 +
* You lose all your config settings if you upgrade from an Rxxx version. (from before ESPEasy v2.0)

I2C is a well known standard to let multiple devices communicate over just two wires (and ground). We use it to connect sensors to ESP Easy. You can connect multiple sensors to the same two wires. Don't forget to use pull-up resistors on both SDA and SCL, unless one of your sensors already has them mounted on board.

=== Tools I2C scan ===
 
If one or more I2C devices are connected to the ESP Easy, you can use this scan feature to verify if devices can be located using their I2C address. If no device is shown, you likely made a mistake on wiring or the I2C configuration in the Hardware page.
 
 
 
If the I2C scanner lists an address, it will also list some well known devices that are fixed or typically found on that address. It does NOT mean that the detected device is verified to work in any way. I2C devices use a 7 bit address and the ESP will just scan all 127 possible addresses. If a device listens to some address it will acknowledge this to the ESP. It does not report the type of device so the ESP can only tell that something is listening!
 
 
 
 
 
=== Tools Settings up/download ===
 
 
 
The ESP Easy settings can be saved to your computer so you can restore them if they are lost or you just want to restore them after some experimenting. You can also upload a custom style sheet.
 
 
 
The system recognizes only two filenames:
 
 
 
'''config.txt'''
 
 
 
This file contains the ESP main configuration settings, except security data. The filesize should be 32k.
 
You can exchange this file with other people if you like, because WPA keys and config password are not stored into this file.
 
 
 
Security data cannot be saved or restored from file!
 
 
 
 
 
'''esp.css''' (Custom Style Sheet, max 4 kb !)
 
 
 
If you want to customize the web gui you can upload (a small) css file. Remember that the webgui is only there for configuration so customization is limited. You may use the following stylesheet as an working example or template for further customization. And don't forget to activate the uploaded stylesheet in the TOOLS>ADVANCED section by enabling the "Custom CSS" option.

Latest revision as of 22:36, 3 February 2021

Welcome to ESP Easy,
the open source firmware for ESP8266 / ESP8285 / ESP32.
Latest builds: GitHub nightly builds
Wiki documentation outdated - Warning
This wiki documentation (for ESPEasy) has become outdated.

Please see ESPEasy ReadTheDocs for more up to date documentation. As not all documentation has been transferred to RTD, this Wiki can still be useful. However, always check the RTD documentation first.

There may be links to older builds online. See GitHub nightly builds for latest builds and releases.


Introduction

The ESP Easy firmware can be used to turn the ESP module into an easy multifunction sensor device for Home Automation solutions like Domoticz. Configuration of the ESP Easy is entirely web based, so once you've got the firmware loaded, you don't need any other tool besides a common web browser.

ESP Easy also offers limited "low level" actuator functions but due to system instability, this could be less useful in real life applications.

ESP Easy is under continuous development as can be seen on the GitHub page and on the Forum.

There are so called "nightly builds" which can be found on the Releases page.


We need support

Funding = a better firmware
We are in great need for funding. The plan is to make this an awesome "operating system" for IoT. We have some big (even huge) features that we want to give you but time is scarce and we need to quit our daytime jobs... Do you want to help us with that? Read more in this announcement here.

Version names, numbers, and branches

Well, this is a short version of our naming convention here at the ESP Easy initiative. We started to call the extensive re-write of the source code "Mega", which is an hint of the size needed for the next big stable release. Prior to mega we allowed smaller mem-sizes (sub-megabyte, aka 512kb) for the official releases. This is a bit tight for our goal to add many more useful features to the firmware. So after a somewhat bad decision in the early days of the re-write project we started to call the development branch "Mega" instead of the more accepted name "Master". We later switched this to the correct name. The current master branch on GitHub is where all the development goes into. The legacy branch is the archive, a point zero if you like, which is the exact copy of the source code before we started the re-write. Once we have reached all the milestones for version 2.0.0 we will freeze the source from that point and fork that into a branch called v2.0, only bug fixes is going into that branch. New features that cannot wait until next v2.1 release will be branched into v2.0.1 (this might not happen if no ground breaking feature is added). New features, and experimental stuff, is poured into the development branch (master). Below you will find a explanation on how we intend to do the branching and releases of future firmware versions. Please observe that this table is not the road map, just an example to explain the different names and numbers.

N.B. this table is outdated and needs to be updated.

Explanation L: legacy freeze (R147 code) D: development (cutting edge) FF: feature freeze R: release of new stable
Branch Tag 2017 2018 2019
Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4
legacy R147 L
development Mega/Knox/Carta D
v2.0 v2.0.0 FF R
v2.1 v2.1.0 FF R
v3.0 v3.0.0 FF?

Tag names

Stable releases will have a version number similar to "v2.0.0" but focusing areas for development will have short tag names such as "Mega" which indicate the focus for the next big release. A preliminary list for the future focus areas are:

Mega which will become v2.0.0 - getting more plugins and much more features (thus the tag "mega" which indicates that a bigger memory is needed for the generic FW)
Knox which will become v2.1.0 - focusing on security
Carta which will become v2.2.0 - focusing on communication unit2unit and unit2controller

As of release mega we will also try to get more hardware specific builds for especially Sonoff units. These will have much less plugins by default since they are not needed for these units, this makes flashing units with less than 1MB possible.

Release names

Nightly builds are always generated if something has been updated in the source code. So the master branch will always have many more releases than the frozen stable releases which will only have one (until a bug fix release is generated). To explain this we provide these examples:

Master is updated on 2018-04.07 with new code, next morning you will be able to download the release "master-20180408" (current tag name for that release is "mega").
Master is branched into an official stable release named "v2.0" on 2018-05-07, next morning you can download "v2.0-20180508".
v2.0 is bug fixed on 2018-05-23, next morning you can download "v2.0-20180524" which then supersede the older v2.0.0 version.

So how do you know which one is the latest?
That's where this wiki is here for (among many other things). We will list all the current states from v2.0.0 and onward. Releases named "master" should always be seen as not stable and only for users that wish to experiment with new releases and test stuff to help the development of future releases.

Get started

Getting started with the ESP Easy takes a few basic steps. In most cases your ESP module comes with the AT firmware or the NodeMCU LUA firmware. We need to replace the existing firmware with the ESP Easy firmware. We provide a (Windows only) flashtool to make this process an easy job. Below you find the general flow of this but an in depth guide is found here.

1. Download firmware as binary including flash tool

2. Connect the ESP to Windows PC
Using either USB/UART of board or separate USB/TTL adapter

3. Write firmware using flash tool
Note necessity for GPIO to be LOW to enter flashmode

4. Restart ESP. WiFi AP "ESP_Easy_0" will appear, password: configesp
(prior to 2.0 the AP was named ESP_0)
If you're not automatically taken to the log-in page, browse to 192.168.4.1

5. Search for you routers WiFi and connect
(if you have multiple AP they will all show up with the same SSID name multiple times)

6. Reconnect to your WiFi and enter IP adress shown on previous screen

Supported Hardware

ESP Easy can be installed/flashed on nearly every piece of Hardware that has an ESP8266 built-in, newest 2.0.0 version even does support the ESP8285 (basically an ESP8266 with built-in 1M Flash).
Please see the list here for more in depth detail about the hardware.

Loading firmware

 On the linked page you will find two daily builds of ESPEasy.
 For some clarification:
 Release V2.0-<date>: Beta version of the next stable release, no new features, bugfixes only.
 Release mega-<date>: Bleeding edge of development.
  • Old release candidate: ESPEasy R147_RC8 (is now part of the dev build for v2.0.0)


2.0+ firmware on 1MB modules

2.0+ firmware on 1MB modules - Warning
If you are running the stock Mega edition firmware on 1MB modules, you will find that you can no longer load newer images because there's insufficient free space to upload the image (344kB as of 2.0.0.-Dev 9 edition). You can compile smaller images to solve this issue or use a small image that has been build just to upload newer images. So you would always have to use a two-step process to renew using OTA on 1MB modules. Using the uploader image as an in-between step, you can use images up to 604kB.
  • Only devices with 1Mb or more flash are supported.
  • To use OTA you need more then 1Mb of flash. (otherwise your device will get unreachable via wireless and you need to fix it via serial)
  • You lose all your config settings if you upgrade from an Rxxx version. (from before ESPEasy v2.0)

ESPEasyUploaderMega

The uploader uses SPIFFS so it uses the same configuration regarding SSID, WPA key and IP. It will connect to your Wifi network as usual, but it will only present this small web page:
