LILYGO® TTGO T5-4.7 Inch E-paper ESP32 V3 Version RF support
-
Hello,
I have an LILYGO
![TTGO T5-4.7 Inch E-paper ESP32 V3] Version and I want to control simulate a controller for my heating boiler. The termostat that I have installed uses a 868,35 mhz frequency. Is there any RF transciever module compatible with my LILYGO?
My plan is to create an WiFi enabled termostat with my TTGO T5-4.7 Inch E-paper ESP32 V3 Version, but first I'll have to decode the communication between my current termostat and the boiler controler. To be more clear,I have made a scheme:
-
Anyone? Any ideas?

@vali I was able to test a similar theory with a pair of 438mhz ones here.
Get any simple RF 868mHz pair of modules (4pin probably), and then record the real device triggering, using the rx module connected to something like a raspberry pi to do the recording. Then play that recording back through the transmit module and see if the boiler triggers. Repeat the trigger test with off and then see if it still works for both. If so you have basic success, now either look at decoding, or just add your own thermometer and send off/on message from the esp instead of raspberry pi. Not that simple in reality but not crazy complex either. Combine a few tutorials/videos...
