The goal of this project is to provide an alternative firmware for Seeed Studio's RFBee.
Using this device connected to a PC or a Microcontroller, it is possible to listen to the communication between a CM67z Central User Panel and one or more HR80 radiator controllers. Further, using this alternative firmware, it is possible to sent commands to the HR80 radiator controllers, e.g. to define temperature settings for a particular "zone" in a building.
The RFBee is a RF module providing easy and flexible wireless data transmission between devices. It is based on a AVR Atmega168 working as a fully functional Arduino connected via SPI to a TI CC1101 RF transceiver.

The firmware was created and tested in an environment with a CM67z Central User Panel and several HR80 radiator controllers. Some of the messages received over the air are well known, while the meaning of other messages remains unknown.
You can contribute by testing this software with other devices of the manufacturer of the devices named above and let us know what you found out, to fill the gaps in the meaning of some yet unknown messages, or to correct or refine the meaning of messages we already know. Your help is appreciated.
