This is a plugin for Indigo (Indigodomo) to allow direct access to some ESPHome sensor devices, and growing over time switches/action devices. This connects directly, locally to the ESPHome device via the local network and requires nothing further. The ESPHome device needs API enabled. ESPHome is a complex, fantastic project and overtime has become very mature/stable.
Many thanks for the enormous man-hours of maintaining and updating this project - it truly is an impressive feat.
So What is ESPHome? (What follows is my, likely limited understanding)
https://esphome.io/
& sensor options: https://esphome.io/#sensor-components
It is essentially firmware for a number of microprocessors, most common, and most powerful the ESP32.
The ESP32, such as this relatively expensive $22 USD one: https://www.sparkfun.com/products/15663
Sparkfun Thing Plus:

This includes a processor, memory, Wi-Fi connection, a number of pins for connecting sensors/devices.
Oh shoot, I read this far and how this seems far too complicated?
Hold off for a couple of minutes...
Sure it sounds somewhat complicated, but actual setup is straightforward.
This above ESP32 option includes a QWIC connection for i2C devices, meaning plug and play for a high number of sensors.
But anyway – on to setup.
Need:
Need ESP32 (or like device) like above, which is $22 USD.
Plug it into a USB port on a computer (Possibly some drivers needed depending on PC).
Go to http://web.esphome.io.
Press the Connect button and find the USB-connected device.
Install the latest version of ESPHome onto the device via the install button on the web.
Enter Wi-Fi details – and in a minute or two, you have a default ESPHome device connected to your Wi-Fi.
Admittedly, it won’t do much – but it connects, and you can visit its web server with its IP in a web browser. It also enables Over the Air updates via the web browser where you can upload new firmware.
See, very easy!
So what now?
Now you need to customize the firmware for the device. To do so, you need to install ESPHome (the software responsible for creating the firmware) on a computer. The firmware is modified depending on the configuration YAML file and is then uploaded to the device, either via the web or via USB.
See: https://esphome.io/guides/installing_esphome
For me, on a Windows device, it was as easy as:
Running the below, having already had a Python3 install:
- Code: Select all
pip3 install wheel
- Code: Select all
pip3 install esphome
Now we have an esphome command (Python script) to create the correct firmware for the device. This does need a YAML file, detailing the device details and any sensors/switches you might have added. Can start with the command, in a directory where the YAML file will be saved.
- Code: Select all
esphome wizard nameofyaml.yaml
And this takes you through basic setup options, then pretty easy to add sensors, and other devices as per the instructions. Once the appropriate code has been downloaded, the firmware bin has been created it then needs to be placed on your new ESPHome device. This is very easy if you can connect via USB, or can use the firmware.bin file and web page for OTA updates.
If you already have an ESPHome device or ‘works with ESPHome device,’ then as long as ESPHome API is enabled on the device, it should be able to connect to it with this plugin.
Why this Plugin?
It enables direct Indigo -> Each ESPHome device communication/connection without the need for anything else. It is a very simple and robust way of getting a huge number of sensors into the Indigo system directly. Sensor updates, or button presses are immediately communicated back to Indigo.
Other options:
The piBeacon Indigo plugin enables similar sensor support/and much more, but rPIs are hard to find, and another level of expense compared to a $5 ESP32. Alternatively, I suspect one of the HA plugins, and then duplicating ESPHome devices from HA into Indigo may also work. To me, this approach is:
1. Simpler.
Uses an ESP32, firmware avoids the cost, and overhead of RPI/SD-Card, formatting, etc. Only possible because of ESPHome, mind you!
2. Avoids the need for other systems/RPI/Computers running elsewhere and complexity of communication risk.
3. Gives us immediate communication in both directions. Other time I hope to expand the device control – lights, switches, plugs, and enable increased support for these types of ESPHome devices. (The issue being there are an infinite number)
This enables direct support for the huge number of works with ESPHome devices.
Okay... So far I haven't mentioned the Plugin... well mainly because I wrote this summary elsewhere and haven't really sorted it out as yet... But that has all changed in the last 5 hours or so...
Plugin:
Download. Install double click. We do have some dependencies., which in Indigo 2023.2+ are automatically managed. - so double click away
Essentially, nothing will happen all going well except the plugin will start.
Next create an ESPHome4Indigo Core Device (the only device option)
Name it ideally before much else...
Enter the IP address of your ESPHome device, password, and port (defaults to 6053)
Press Save:
& All the Sensor devices, and all the Switch devices connected to this ESPHome device will be created in Indigo. Live updating and the ability to turn on/turn off switch devices currently.
These Sensor and Switch devices will be all grouped together in one Device Group. But they are all separate standard indigo devices and can be exported into other ecosystems (like Homekit) without problem. (via HomekitLink plugin)
If you need to recreate Devices as have some changes - delete current devices (sorry might update this aspect) and then press Recreate Devices. All Sensors and Switches (the only devices this version supports are created as a Device Group) The main Core device I have left outside of this group so you can delete and add sensors etc. more easily.
