Overview
ramses_rf is a Python client library/CLI utility used to interface with some Honeywell-compatible HVAC & CH/DHW systems that use 868MHz RF, such as:
- (Heat) evohome, Sundial, Hometronic, Chronotherm
- (HVAC) Itho, Orcon, Nuaire, Vasco, ClimaRad
It requires a USB-to-RF device, either a Honeywell HGI80 (somewhat rare, expensive), a USB/MQTT dongle running the ramses_esp, evofw3 firmware, such as the one from here, your own ESP32-S3-WROOM-1 N16R8 with a CC1100 transponder or a combination of dongles for better RF coverage.
It does four things:
- decodes RAMSES II-compatible packets and converts them into useful JSON
- builds a picture (schema, config & state) of evohome-compatible CH/DHW systems - either passively (by eavesdropping), or actively (probing)
- allows you to send commands to CH/DHW and HVAC systems, or monitor them for state changes
- allows you to emulate some hardware devices (remotes)
For CH/DHW, the simplest way to know if it will work with your system is to identify the box connected to your boiler/HVAC appliance as one of:
- R8810A: OpenTherm Bridge
- BDR91A: Wireless Relay (also BDR91T)
- HC60NG: Wireless Relay (older hardware)
Other systems may well work, such as some Itho Daalderop HVAC systems, use this protocol. YMMV.
This library includes a CLI and can be used as a standalone tool, but also is used as a client library by:
- ramses_cc, a Home Assistant integration
- evohome-Listener, an MQTT gateway
Our Code of Conduct applies to all use of this repository and the code it creates.
Installation
To use the ramses_cc Integration in Home Assistant, just install Ramses RF using HACS. It will take care of installing this library. See the Ramses_cc wiki for details.
Ramses_rf CLI
To install the ramses_rf command line client:
git clone https://github.com/ramses-rf/ramses_rf
cd ramses_rf
pip install -r requirements/requirements.txt
pip install -e .
The CLI is called client.py and is included in the code root.
It has options to monitor and parse Ramses-II traffic to screen or a log file, and to parse a file containing Ramses-II messages to the screen.
See the client.py CLI wiki page for instructions.
For code development, some more setup is required. Please follow the steps in our Developer's Resource
