Tyxia 5630

[maxmouchet]

Hi,

Thanks for the reverse engineering effort!

My home is setup with multiple Delta Dore devices:

• A Tydom Home
• A Tybox 2020 WT thermostat + electricity/gas consumption + roller shutters control.
• A Typass CHX for interfacing with a Chaffoteaux Mira C Green Ultra boiler.
• Tyxia 5630 and 5730 roller shutters receivers.

Ultimately I might move everything to standard Zigbee devices as the proprietary and undocumented nature of the Delta Dore devices & protocols is very frustrating, but for now I thought I might contribute some data to this project :)

I've captured X3D messages with rtl_433 while setting the position of one of my shutter:

rtl_433 -f 868.95M -R 269 -F json

Here are the files for 0, 25, 50, 75 and 100%:
shutter.0.json
shutter.25.json
shutter.50.json
shutter.75.json
shutter.100.json

Here are some stats computed with DuckDB:

SELECT id, action, register_high, register_low, raw_msg, COUNT(*) messages
FROM 'shutter.X.json' 
GROUP BY ALL
ORDER BY messages DESC

Of interest is the 16/33 register which seems to encode the position:

• 0% = 0x00 0x00 = 0 / 0
• 25% = 0x19 0x65 = 25 / 101
• 50% = 0x32 0x65 = 50 / 101
• 75% = 0x4b 0x65 = 75 / 101
• 100% = 0x64 0x64 = 100 / 100

Ok, thanks.
Hm, at first, it looks like I've a bug in the rtl_433 implementation, the first two bytes in the Register Raw data are missing.

• 16 33 (0x10 0x21)
  • looks like you mentioned, the second byte could contain some control flags, up, down, slow ,fast ??
• 16 17 (0x10 0x11)
  • looks like read of the current target height, maybe the second byte is flag for current moving.

I will investigate on rtl433 bug.

[mr-sven]

Ok, you can try: https://github.com/mr-sven/rtl_433/tree/deltadore

On anylsis I've seen the following.

• your tydom, ID 11065963
• device 1, bitmask (0b0001 = 1) Thermal control device (RF 66xx or Typass CHX) because of following messages in log:
  • 0x15 0x11 - (r) Current Room Temp
  • 0x16 0x11 - (r) Current Target Temp and status
  • 0x16 0x41 - (r/w) On/Off state
• device 2, bitmask (0b0010 = 2) Shutter ?
• device 3, bitmask (0b0100 = 4) Shutter ?
• device 4, bitmask (0b1000 = 8) Shutter you tested

Thanks a lot! There's indeed two more bytes now in raw_msg.

There are indeed 4 shutters. Setting them one-by-one to 90% I see the following values for 16 33:

1. 5a65 (90 101)
2. 00005a65
3. 000000005a65
4. 0000000000005a65

Creating a group with all 4 shutters on the Tydom and setting it to 90% we see a single message: 5a655a655a655a65. So far, so good.

Still unclear on the value of the second byte. It seems to always be 65 when going up or down, excepted 0 when position = 0% and 64 when position = 100%. Maybe something to do with favorite shutters position?

[mr-sven]

ah, yes you are right, the thermal control device is in the other X3D network.
Is there any difference when you press the buttons on the shutter controller?
