 ====== Implementing support for the device in rtl_433 ======
-Yet to be done...
+Adding support for the heating control in rtl_433 is actually quite easy, once you realize that OOK_PULSE_CLOCK_BITS is actually differential Manchester encoding. Unfortunately, bit-unstuffing and changing bytes from least-significant-bit first to last needs to be done manually.
+All this can be seen in my Pull request for the rtl_433 github repo: https://github.com/merbanan/rtl_433/pull/532/
+If you clone this PR (or use the latest rtl_433 once it is merged), one can tune rtl_433 to 868MHz and see the captured signals analyzed:

+====== Implementing support for the device in RFLink ======
+Yet to come (I don't have a 868MHz receiver for RFLink yet, and RFLink does not support both 433MHz and 868MHz receivers at the same time, so I'm waiting until they implement support for the CC1101).
