Monitoring and controlling an Itho Daalderop CVE RFT #5

Open reneklootwijk opened 3 years ago

reneklootwijk commented 3 years ago

By coincidence I noticed my Itho Daalderop CVE RFT uses the RAMSES-II protocol for communication with the RF remotes.

The remote has 4 keys and the 4th key activates a timer. The timer depends on the number of key presses (1-3). When a button is pressed it broadcast a message 3 times.

For mode 1 (low) the following messages are send:

067  I 132 --:------ --:------ 63:163409 22F1 003 000204

63:163409 is the address of the remote, my other remote uses: 62:228945

For mode 2 (normal) the following message is send:

060  I 133 --:------ --:------ 63:163409 22F1 003 000304

For mode 3 (high) the following message is send:

065  I 134 --:------ --:------ 63:163409 22F1 003 000404

For mode 4 (timed high) the following messages are send for 1 key press (timer=10m):

067  I 135 --:------ --:------ 63:163409 22F1 003 000204
053  I 136 --:------ --:------ 63:163409 22F3 003 00000A

For mode 4 (timed high) the following messages are send for 2 key presses (timer=20m):

067  I 137 --:------ --:------ 63:163409 22F1 003 00000A
053  I 138 --:------ --:------ 63:163409 22F3 003 000014

For mode 4 (timed high) the following messages are send for 3 key presses (timer=30m):

067  I 137 --:------ --:------ 63:163409 22F1 003 000014
053  I 138 --:------ --:------ 63:163409 22F3 003 00001E

Controlling also works by sending the following for instance:

I --- 18:000730 --:------ 63:163409 22F1 003 000404

Please format your post - I have done a start for you.

Have a look at:

Also look at 31D9, and 31DA.

You can capture packet logs and try things like:

cat packet.log | python client.py parse

You can post to @Raqbit here: https://gitter.im/evohome_rf/community

He & you may be able to collaborate further.

I have switched to an MIT license, here and at evohome_rf - enjoy!

Apparantly you already knew part of it. I will now try to pair my code as a new remote to the Itho CVE.

My node.js module is alsmost finished, so I use my own code to monitor and try things.

I see 31D9 and 31DA messages from toher unknown devices, with id 20: and 37:. Does this sound familiar.

BTW thanks for using the MIT license!

Yes - have a look in evohome_rf/parsers.py - all that is known by me is in there!

(except for the sequence # issue)

@Raqbit may know more
