Weird payload used in sent message #11

Open sidious38 opened 4 weeks ago

sidious38 commented 4 weeks ago

Thank you very much for implementing this project; I came across it after a long research regarding my Weinor blinds... As described in the instructions, I obtained and soldered a C1101 radio module for 868MHz and can receive all commands. Unfortunately, sending doesn’t work as expected:

In the payload, I noticed that it does not match the received payload. Is this intentional? Shouldn’t the message simply be "copied," or did I misunderstand the concept?

[22:50:44][VV][elero:474]: send_command called
[22:50:44][V][elero:504]: send: len=29, cnt=03, typ=0x6a, typ2=0x10, hop=0a, syst=01, chl=17, src=0x82a501, bwd=0x82a501, fwd=0x82a501, #dst=01, dst=0xa46d20, payload=[0x00 0x03 0xc3 0xd6 0x2f 0x3a 0x49 0x85 0xc3 0x31]
[22:50:44][VV][elero:206]: transmit called for 29 data bytes
[22:50:44][VV][elero:151]: wait_rx
[22:50:44][VV][elero:177]: wait_tx
[22:50:44][VV][elero:191]: wait_tx_done
[22:50:44][V][elero:231]: Transmission successful

How the received message looks like (STOP):

[23:03:24][VV][elero:015]: loop says "received"
[23:03:24][D][elero:451]: rcv'd: len=29, cnt=114, typ=0x6a, typ2=0x10, hop=0a, syst=01, chl=17, src=0x82a501, bwd=0x82a501, fwd=0x82a501, #dst=01, dst=a46d20, rssi=-58.0, lqi=42, crc= 1, payload=[0x00 0x03 0x00 0x00 0x10 0x00 0x00 0x00 0x00 0x40]

Could this be the problem why sending the commands is not working?

Please post the YAML configuration of this blind, it's hard to say without knowing what you configured.

Your configuration seems right to me. Regarding your questions: The log file contains the decrypted received commands, but the encrypted sent commands - that's why they differ so heavily. I agree that this is somewhat confusing.

In the Home Assistant forum, a user reported a similar problem with the same payload_2 type (0x03) as yours (mine had all 0x04 and we have a mixture of RolTop, RolTop-J, RolMotion and Combio motors/receivers): https://community.home-assistant.io/t/elero-usb-transmitter-to-control-elero-and-weinor-products/52740/259. Maybe the protocol is slightly different on these blinds?

Do you know which motors you have exactly? And which remote control?

sidious38 commented 3 weeks ago

The remote is called BiEasy-5M, which should correspond to a VarioTel-2 remote (the contents of the manual are exactly the same). I don't know anything about the motor, but it seems like they just rebranded an Elero motor for Weinor.

I've read in reviews of the VarioTel-2 remote that some people use it to control Weinor blinds, so I think it must be possible to reuse your library. I will try to analyse the learning process as it might be possible to learn the virtual remote as a second remote for the blinds. At first glance, the learning process didn't seem too complex when I analysed the messages, but I will have to adapt the source code. Maybe I'll be successful.

Thank you for the effort you have already put into this program!
