Honeywell CM700 series with BDR91 relay box

---

Hello ,

did someone manage to decode the signals from this heating thermostat ? It’s working in 868Mhz, but with homeduino with 868Mhz receiver it’s not detecting the messages.

Homeduino with 868mhz receiver? How did you do that?
Homeduino uses 433mhz, so this cannot work.

On homeduino id does not mater what kind of freq you use on the end as long the signal is TTL and it is the right data is received homeduino will decode it.I tested with 433,868 ,ASK ,FSK modules . The CM700 uses OOK modulation at 868 and bidirectional communication and it’s a bit more complicated because the 868 channel is also not fixed it jumps around 868.1 and 868.9 Mhz …

ah … ok i see! thx for clarification
