This repository contains various ESPHome configurations, to extend my Home Assistant instance with custom sensors and controllers. The goal was to group several functionalities on one controller (save energy) and enable old/ existing hardware in my houshold with smart IoT funtionalities (avoid electronic waste).
This ESPHome configuration acts as a bluetooth sensor data proxy, to make the data of Thermo-Hygrometer Govee H5105 visible in a HomeAssistant sensor entity. The configuration will listen to the Bluetooth Low-Energy advertise packets of the sensor, parse the sensor data out of that messages and provide the sensor values to HomeAssistant.
The pc.yaml config was made for a ESP32-C3 with a RISC-V CPU, but the it could also be adapted for any other ESP32 controller with Bluetooth. The config also contains an switch component to remote control an attached relay.
This is a implementation to remote controll a Honeywell HR-20 radiator regulator in a Home Assistant instance. To control the radiator over UART, an ESP Microcontroller is used. The communication between Home Assistant and the Microcontroller is done with the ESPHome framework. Therefore an ESPHome Custom Climate Component was created, which will send/ receive the commands to/ from the Honeywell radiator regulator.
This repository contains one implementation for the Honeywell HR-20 Hardware version 1 and another one for Hardware version 2 with OpenHR20 firmware. The implementation was tested with the NodeMCU v3 (ESP8266) and ESP32 as IoT getway to remote control the heater.
The UART protocoll for Hardware version 1 was reengineered, to manipulate the memory over a programming/debugging UART interface (protocol. The protocoll for the OpenHR20 firmware can be found here
Here is a wiring example:
- Follow the instructions from ESPHome
how to setup the build & deploy toolchain on your host.
- Initial flashing must be done over wired USB connection. Afterwards it can be done OTA.
- Deploy the C++ header files and the ESPHome YAML from honeywell_HR20_controller
to the shared config directory of the toolchain.
- When you run the ESPHome docker container, you also specify where this shared config directory shall be mounted.
- Open the ESPHome dashboard (usually http://localhost:6052/) and install the config from this project.
- Install ESPHome in your Home Assistant instance. Follow this guide.
- Add the related ESPHome entities to your Home Assistant Dashboard.
The inital version of this repository (git tag V1.0) was implemented to work with Legacy blynk.io. With minor adaptations it should also work with the latest blynk version. However the blynk implementation of this project is discontinued and replaced by Home Assistant.
