Oh, that indeed sounds interesting. I also bought additional X3D window sensors for my thermostat/heater combos which are assigned via the heater. I probably could get hold of some RTL-SDR compatible h/w to help with that project. I just need to figure out what I need to be compatible with the 868MH...

That will not work...

Mhh, ok, too bad, good to know, guess I will give up on tinkering with the 868Mhz rflink then.

I guess I'm trying to get hold of an Aurel FM/FSK 868MHz transceiver instead of the AM/OOK one and see if I can get anywhere with it.
It seems to be difficult to get those as a drop-in replacement for the AM/OOK one on the rflink as 5V version lately, though.

I think I give up on the 868MHz X2D/X3D stuff for now. I got a 433MHz rflink instead which at least works nicely with my Oregon Scientific temp/humidity sensors and my motor controlled roller shutters instead. :) The Delta Dore modules probably use a different modulation or slightly off frequency wh...

It's a DeltaDore OEM thermostat Device which has a TAP PILE OEM RETRO BLEU 7719934 product sticker attached. Some reference I found is at https://www.heizstrahler-shop24.de/heizstrahler-dateien/infralogic/datenblatt/DeDo%20Thermostat.pdf There is also a companion control unit attached to the heater....

Yea, thanks for feedback, understood. Unfortunately, it is a bit difficult to create debug data without any reception at all. So either there is some problem with the 868.3 MHz Aurel transceiver which doesn't receive anything at all or the actual X2D/X3D thermostat/heater uses a slightly different f...

Thanks, actually modified the line to
in order to have some i/o terminal and to be able to send commands to RFLink as well but the channel stays pretty much silent ...

Yea, I got mine prebuilt from nodo-shop.nl as well. Unfortunately, I have no clue if the rflink is properly working at all or is there some kind of selftest/loopback mode which could achieve the check/test ? At least the firmware seems to work as expected. I probably was a bit too optimistic when I ...

Also, what is the deal with the 868MHz frequency range ? I guess if the RFLink transceiver (mine is a Aurel 868.3 MHz Transceiver) works at 868.3Mhz, it also uses this as the center frequency and wouldn't work out of that range ? My X3D thermostat technical info mentions 868,7 to 869.2 MHz, so I gue...

Just to revive this thread again ... What is the status of X2D/X3D support in firmware r48 ? I'm new to this forum and came across RFLink to access my Delta Dore X2D/X3D driven thermostats/heaters. Unfortunately my 868 RFLink doesn't receive anything at all of the RF traffic. Is there any documentat...
