Hello ! I want to build a IoT project and I was wondering if anyone can help me out with something. At least to know if it's doable. I have a Thermostat to control the temperature that works on 866Mhz, it says so in the specifications. I also have a LoRa RF95 that works on the same frequency. Is there any way I could capture the thermostat signal? After that I want to send it back using another LoRa. I know you can send packages and make 2 Arduinos communicate between one another using two LoRa modules. I just want to "clone" the termostat signal instead.
I doubt it. LoRa's physical network layer is proprietary and complex. I'll guess that your thermostat isn't using it and is just transmitting in the clear on a single frequency. Since you have both devices, you could try it, but I would expect to get nothing at the LoRa device.
You would probably need a simpler radio to receive the signal from the thermostat which you could then retransmit using LoRa.

Potentially yes.
The LoRa devices support FSK and GFSK modes as well as LoRa and a lot of sensor type devices operate using FSK type communications.
Good luck.
