HomeAssistant custom integration for a virtual Itho RFT remote using the evofw3 gateway.

Itho RFT integration for Home Assistant

!!! This integration is in an early stage of development so use at your own risk and contributions are welcome. !!!

!!! This integration implements the Itho RFT AUTO (536-0150) remote. Support for other remotes can be added if requested. !!!

!!! This integration is tested with an Itho HRU ECO300 unit paired to a Itho RFT CO2 sensor. The implemented remote is the Itho RFT AUTO (536-0150). !!!

Home Assistant custom-integration that integrate with the pyIthoRFT library.

Hardware

This integration requires a evofw3 gateway running version 0.7.1. This repository contains links and instructions how to obtain/build a gateway.

I've created my own €16,- gateway including shipping using the following components:

• Arduino Pro Micro 3.3V 8MHz
• EBYTE E07-900M10S
• 868Mhz 3dBi

To build the software for this DIY gateway, follow the README instuctions from the evofw3 repository except for selecting the pinout configuration. Use: Tools -> pinout -> SHA atmega32u4.

Below the connections table and this is what my clumsy DIY gateway looks like :).

Installation

Add haIthoRFT as HACS custom repository

• Select HACS (side panel), Integrations.
• Select the three-dots menu on the top-right, select Custom repositories.
• Add the repo URL (https://github.com/GraceGRD/pyIthoRFT), Category is Integration.
• Click the Add button, and close the window (X in top-right).

Add Itho RFT as integration to Home Assistant

• Select HACS (side panel), Integrations.
• Select Explore & Download Repositories button.
• Search for 'Itho RFT' and select the repository.
• Install the repository by clicking download and confirm.
• Restart Home Assistant (the HA Core)

Configuration is done in the UI

1. Configure the gateway port e.g. /dev/ttyACM0 and press SUBMIT. Under the hood the communication with the gateway is checked.
   
   
   
   
2. Choose pairing method:
   - Automatic pairing randomly generates the remote address which is then used for pairing.
   - Manually pairing requires a remote and a unit address. This can be used to re-configure a paired remote, or copy a physical remote.
   
   
   
   
3. Provide the Remote and Unit address in manual pairing mode and press SUBMIT.
   
   
   
   
4. Put the unit in pairing mode as described in the manual then press SUBMIT to start the pairing process.
   
   
   
   
5. When pairing succeeded (manual or automatic pairing) the following message should pop up showing the port, remote and unit address.
