Correct, this sensor is not listed in the RFXtrx User Guide as supported.

This banggood sensor is listed as supported:

I know have also those and they do work.
This one works with RFLink so I hope that they will be able to also added it into RFXtrx.

I have also purchased this one:

and will report back if it is working.

I prefer the one without lcd display.

I've got a Digoo TH8868 and a TH8888.
Very nice displays, but the remote sensors are not seen by RFlink nor RFX.

Yes we know that, but we are also testing some others models.
Would it be possible to change only the transmitter part and will it then work or not? Probably not?

Hello
In my experience signal form is :

Header : 650ms high and 8000ms low
Body : a set of 36 bits
bit 0 : 650ms high and 2000ms low
bit 1 : 650ms high and 4000ms low

bit 0-13 : id (seems different for each sensor. When you press test, id send id+1. When you reset power, id can be different)
bit 14-15 : channel-1 (select)
bit 16-27 : temperature in degre (must be divide by 10. for exemple 298 = 29.8)
bit 28-35 : humidity (assume 10 seems = LL from panel)

I tested with esp/arduino code using attachInterrupt(digitalPinToInterrupt(D7), change_D7, CHANGE); and change_D7 custom function

Good luck

I can confirm that the DG-R8B sensor works now.

Hi Maikie, Could you tell me how you added the DG-R8B device?
