ramses_cc is a Home Assistant custom integration that works with RAMSES II-based RF 868 Mhz systems for (heating) CH/DHW (e.g. Honeywell Evohome) and (ventilation) HVAC (e.g. Itho Spider, Orcon).
This includes CH/DHW systems such as evohome, Sundial, Hometronic, Chronotherm and others.
The simplest way to know if it will work with your CH/DHW system is to identify the box connected to your boiler (or other heat source) to one of (there will be other systems that also work):
- R8810A or R8820A: OpenTherm Bridge
- BDR91A or BDR91T: Wireless Relay
- HC60NG: Wireless Relay (older hardware version)
ramses_cc also works with HVAC (ventilation) systems using the same protocol, such as from Itho, Orcon, Nuaire, Ventiline, Vasco, etc.
It uses the ramses_rf client library to decode the RAMSES-II protocol used by these devices. Note that other systems may also use this protocol. YMMV!
The library requires a USB-to-RF device, either a Honeywell HGI80 (rare, expensive) or a USB/MQTT dongle running ramses_esp or evofw3, such as the one from here or your own ESP32-S3-WROOM-1 N16R8 with a CC1100 transponder.
