evohome-rf 0.8.6

An interface for Honeywell RF (RAMSES II), as used by HVAC, CH/DHW.

evohome_rf

It does three things: a) convert the RF packets in useful JSON b) builds a picture (schema, config & state) of an evohome-compatible system - either passively (by eavesdropping), or actively (probing) c) allows you to send commands to evohome

It provides services to https://github.com/zxdavb/evohome_cc, a Home Assistant integration

It requires a USB-to-RF device, either a Honeywell HGI80 (rare, expensive) or something running evofw3, such as the one from here.

Installation

git clone https://github.com/zxdavb/evohome_rf
cd evohome_rf
pip install -r requirements.txt

You may want to clean up/create a virtual environment somewhere along the way, something like:

deactivate
rm -rf venv
python -m venv venv
. venv/bin/activate
pip install --upgrade pip

Instructions

python client.py monitor /dev/ttyUSB0

Be sure to have a look at -o packet_log.out and -p (probe).
