StamPLC Home Assistant Integration

StamPLC is an IoT programmable logic controller designed for industrial automation and remote monitoring. The product uses the Stamp-S3A control module, providing strong processing power and efficient wireless connectivity. This document explains how to integrate StamPLC into Home Assistant.

Preparations

• A Home Assistant host
• Install and enable the ESPHome Builder add-on in Home Assistant

Open ESPHome Builder in Home Assistant and create an empty configuration file:

• Click the NEW DEVICE button at the bottom right
• In the dialog click CONTINUE

• Select Empty Configuration

• (Optional) Give the file a name

• Click EDIT on the newly created configuration file

Then copy the contents of configuration.yaml from the example repository into your config file:

Modify network or API information as needed. For example, create an API Encryption Key for authentication:

api:
  encryption:
    key: "Your_Encryption_Key"

You can also change the timezone setting, for example:

timezone: America/Los_Angeles # Pacific
# timezone: America/New_York # Eastern

After editing, click SAVE and then INSTALL, choose Manual download.

This will generate code and compile the project.

When the build finishes, select Factory format to download the firmware.

Open ESPHome Web in your browser to upload the firmware.

Connect StamPLC to the host via USB-C, click CONNECT and select the device.

Click INSTALL, select the previously downloaded firmware, and click INSTALL again to flash the device.

After flashing completes the device will automatically reset and boot.
