Need Help defining Protocols for Atag Kitchen Extractor (afzuigkap) and Generic Doorbell

[MRvH88]

If been successfully using a Sonoff RF Bridge with Tasmota and Portisch for a while now, however I am only able to send RFraw signals and I am not able to receive these signals without sniffing for B1 signals. Would it be possible to receive these signals without B1 sniffing by defining these in RF_Protocols.h?

I have sniffed and converted the following signals for my Atag Kitchen Extractor and Generic Doorbell, these signals work 100% of the time. I have tried the to use the Wiki to define te protocols, but I kinda get lost. Can somebody assist me with creating these protocols?

I too have been trying to find an answer to this. I would like to be able to receive these signals without sniffing for B1 signals so that I can allow my sensors in home assistant to keep their state. I’ll stay tuned.

[Portisch]

Try sniffing again with the latest master!

I close the issue because of a buggy EFM8 firmware - please do a 0xB1 sniffing again and I will reopen the issue.

[MRvH88]

Thanks for the reply! Used the latest master and the received B1's are indeed much much better and more consisted!

I used the new master to sniff B1 and converted them B0 for the extractor (no time for the doorbell yet unfortunately).

The new B0 are all working correctly, however I would also like to receive the signals from the remote itself without having to turn sniffing on. Am I correct to say that if I use below codes and define them in RF_Protocols.h, I would be able to see receive them without sniffing?

I have tried to use the Wiki to define the protocols, but I kinda get lost. Can somebody assist me with creating these protocols?

This is strange. You have 2 differnent bit counts for the same remote? Like Up/Down is the HT12A protocol. The Light/Timer is the same as HT12 but with 18 bit insteed of 12!? This is hard to implement because both protocols would be triggered but when 12 bits are reached all decoding is getting stopped. So you never will get the 18 bits decoded.

I modified the HT12 settings: Atag branch May you try if it is working with only 12bits. Take a look to wiki commands: 0xA6, 0xA8,...

The default sniffing is like the original. If you implement your remote in Protocols.h you have to activate as minimum 0xA6 sniffing. How to handle this you have to ask at Tasmota forum.

[MRvH88]

@Portisch Thanks for the work on the Atag branch!! I will try to flash it today to see how it works. Concerning the differences between +/- and light/timer, that might me my mistake (still learning), I changed the bucket times to see if I could find common buckets that would fit for the protocol. The buckets for light and timer are a bit different than the ones for +/- but they are working with the ones I added above. Below is a list of sniffs I did for the four options.

Here is the total list of sniffs:

Besides the Atag remote I also sniffed my doorbell and found that I get multiple outputs per ring (I think this is because I can set multiple channels so it does not ring if my neighbors use the same one).

I sniffed and received the following list from which only the first one is working after converting it to B0:

Used the Atag branch with rfraw AAA655 and +/- is indeed working and giving output: 00:00:39 MQT: Sonoff_RF_Bridge/tele/RESULT = {"RfRaw":{"Data":"AAA60306555055"}} 00:00:43 MQT: Sonoff_RF_Bridge/tele/RESULT = {"RfRaw":{"Data":"AAA60306556055"}}

As you mentioned, light/timer is not outputting anything as expected.

[MRvH88]

@Portisch Many thanks to you! I reversed engineered your RF_protocols.h and added the protocols for both the light/timer and the doorbell and compiled them and can receive all three now. The 0x03 version really is a huge improvement!

Only thing now is that my doorbell comes in twice with a single ring, but I guess that is probably because of the repeat?

[Portisch]

Good, may you make a pull request!?

[MRvH88]

@Portisch are the defined protocols still subject to a maximum number as in the previous version or can more protocols be defined with version 0x03?

[Portisch]

Until the efm8 is running out of memory...
